Arrays with millions of small micron holes

noreply@blogger.com (Lenox Laser Inc.) — Fri, 26 Apr 2013 22:09:00 +0000

Lenox Laser has once again pioneered a new small hole drilling capability. We are now able to drill arrays with millions of micro holes down to 1 micron in size. We are able to drill in a myriad of materials (Tungsten, Moly, Stainless Steel, Silicon) with spacing down to 15 microns. The hole sizes, shapes, and spacing can all be customized per your application. Some ground breaking applications include nozzles, lab on chip sensors, DNA analysis, beam shaping, and CMOS biotechnologies.

Please check out our Scanning Electron Microscope(SEM) photos showing a sample of our arrays.

Lenox Laser's 30th Anniversary Year Brings More Industry Breakthroughs.

noreply@blogger.com (Lenox Laser Inc.) — Wed, 22 Aug 2012 14:11:00 +0000

We have been pretty busy this past year- here is a quick update on a little of what we have been doing!

Not only has Lenox Laser set the standard for sub-micron hole drilling repeatability, but we also do it fast. We can now produce over 1 million holes per hour, setting a new record in laser drilling . That may be more holes (total) than we have drilled in our 30 years of operation.

The Archimedes Palimpsest and Lenox Laser

noreply@blogger.com (Lenox Laser Inc.) — Wed, 19 Oct 2011 16:24:00 +0000

Lenox Laser, as mentioned in the previous post, is involved and relevant to current events such as the recent Nobel Prize in Physics and the James Webb Telescope.

Photo from the Walter's Flickr site, part of the Lost and Found exhibit about the Archimedes Palimpsest

Another example is the Archimedes Palimpsest at Baltimore's Walters Art Museum. It is on a special exhibit right now until January 2012, and, believes it or not, Lenox Laser was involved with this as well! Lenox Laser was involved in the key science that allowed them to see past the monk's writings and read Archimedes' instead. SLAC was the organization that was heading up the research to better read the obscured text, and they contacted Lenox Laser for the special tungsten part.

From our earlier blog post about the Archimedes Palimpsest from 2006- it explains Lenox Laser's key role.

The Archimedes Palimpsest writings lingered unseen for centuries, seemingly purged from the documents forever, until Professor Heiburg began to review small scrawls beneath the visible text. At SLAC, a revolutionary modern analysis of the writing medium has been made - revealing they do contain historically important information left behind by Archimedes, Hidden from the naked eye.When confronted with an engineering challenge involving their Synchrotron X-Ray source, SLAC issued a request to Lenox Laser to produce microscopic laser-drilled holes in thin Tungsten film. These small apertures would prove critical to the team's success in uncovering the Palimpsest's "hidden treasure".

Earlier this month, on October 4, we had Dr John C Mather speak at our 2nd International Light Seminar. He received the Nobel Prize in Physics in 2006 for his part in the COBE mission regarding the Big Bang theory and the expansion of the universe.

On that very day, the Nobel Prize in Physics was given to another group of scientists also doing work on dark matter and the expansion of the universe, showing that it was in fact rapidly expanding, not slowing down as previously thought. You can read more about this year's Nobel prize in their press release here. Dr Mather alluded to the recent prize and their work in his talk since it related specifically to the things he has studied.

Lenox Laser Online Calculators- Revisited

noreply@blogger.com (Liesl M Heerdt) — Tue, 23 Aug 2011 16:12:00 +0000

Our free online calculators are one of our best resources. They consistently get the top hits on our website and blog. The main page for our calculator applications website is here. Here you can see we offer three free calculators:

Orifice Calculator

Unit Calculator

Diffraction Calculator

-The Orifice Calculator does critical orifice calculations. On our website it stands alone, so for more information, this post- the Free Online Critical Flow Orifice Calculator on our blog goes into the specifics with more detail. And of course, for more precise calculations, please contact us.

-The Unit Calculator is a unit converter- simple, yet very helpful when using the website and placing orders.

-However, the Diffraction Calculator is perhaps the most fun, due to the visualization of all the different types of apertures, slits, etc. The applet is fun and informative to play around with, and certainly can be used in education to illustrate the different effects.

Special thanks goes to Paul Falstad, and check out www.falstad.com to see more of his applets about science and physics.

Keep checking in for more posts, and please visit us at www.lenoxlaser.com to see our full line of products or to place a custom order.

Lenox Laser Scholarship- "Evaluation of UV LEDs for detection of atmospheric NO2 by photolysis- chemiluminescence"

noreply@blogger.com (Liesl M Heerdt) — Thu, 14 Jul 2011 15:56:00 +0000

"Evaluation of ultraviolet light-emitting diodes for detection of atmospheric NO2 by photolysis- chemiluminescence"
by Ilana B Pollack, Brian M Lerner, and Thomas B Ryerson

This article was accepted to Journal of Atmospheric Chemistry in February of this year, and it details an atmospheric study done in May and June of 2010. Lenox Laser made a total of 3 parts for their studies of different LED detections systems of NO2. For some key background information if one is not familiar, I highly recommend reading this article first:
Flourescence detection of atmospheric nitrogen dioxide using a blue light-emitting diode as an excitation source by Yutaka Matsumi et al. It is much more readable and understandable.

Basically, detection of NO2 in the atmosphere relates to the ozone levels in the atmosphere. Thus, scientists of the field are interested in better, more accurate, and cheaper ways to measure NO2. One of the most recent trends to do so is to use commercially available UV-LEDs in their systems. The systems already often use a UV light source of some kind because in the chemistry of NO2 and related molecules, they will emit light in the process. Atmospheric scientists use this property, called chemiluminescence, to measure the NO2 molecules. Chemiluminescence detection is called P-CL.

In this article, the authors tested 3 UV-LEDs against each other in the P-CL system as shown in the diagram below:

Fig 1 from the paper- schematic of instrumental configuration

I recommend reading the article itself to fully understand the diagram and the process. However, this is where Lenox Laser and our calibrated orifices come in. The red section where it says 700um orifice is where our first orifice was used. This is the bypass inlet, and was used to set the sample flow rate and cell pressure for the entire system. They found that the Nichia LEDs were the best overall.

So for the second part of the test, they took the Nichia LEDs on board the NOAA WP-3D aircraft with the P-CL for "on the job" training in the CalNex study. They replaced the more expensive and complicated mass flow controllers were replaced with our critical orifices and mass flow meters. In the diagram above the two places are indicated by arrows in the blue and black section. Replacing the parts in the system did improve the quality, and, as stated in the conclusion, they "eliminate mechanical components with complex flow paths that degrade time response. Replacing mass flow controllers with critical orifices and mass flow meters further simplifies the sample flow path in these laboratory test."

The NOAA WP-3D aircraft is the plane that flies into hurricanes to monitor and gather information. It took part in CalNex - a study by several universities and institutions of air quality and climate change on the west coast. Our parts were used on board and tested with the UV-LED systems during the study. They even went with the plane as it was briefly diverted from the study to the Gulf of Mexico during the oil spill.

So in conclusion, this research paper incorporates optics, chemistry, and biology with flow technologies, atmospheric studies, and research planes all together, with Lenox Laser parts in the middle of it all!

Spectrum of Industrial and Scientific Lasers

noreply@blogger.com (Liesl M Heerdt) — Tue, 28 Jun 2011 16:03:00 +0000

The first laser ever made used a synthetic ruby crystal- a solid-state laser with an emission wavelength of 694 nanometers.

Now, over 50 years later, lasers can be from solids, liquids, or gases. They span the electromagnetic spectrum from far-infrared to the edge of ultraviolet, and emit wavelengths from 3 micron to 157 nanometers.

The full diagram of commercial lasers here at Wikimedia Commons.

We made a new and revised chart from the data showing more specifically the industrial and scientific lasers used in micro-drilling applications.

click here to enlarge

From the description:

"Laser types with distinct laser lines are shown above

the wavelength bar, while below are shown lasers

that can emit in a wavelength range... the height of

the line gives an indication of the maximal power/pulse

energy commercially available. For the Ar+-Kr+ laser

only the most important lines are labeled...

Currently most of the data is taken from Weber's book

"Handbook of laser wavelengths", with newer data in

particular for semiconductor lasers."

From the original, we switched the bar around to go from longer to shorter wavelengths, instead of the other way around. Otherwise, it's the same data. It gives a nice visual overview of the laser spectrum and their myriad types.

Next week I'll be writing about an exciting research paper from NOAA for which we made 3 key parts. It connects atmospheric research, WWII planes, Hurricane Katrina, UV-LEDs, and Lenox Laser orifices all together! So be sure to check back.

And as always, check out past posts and our company website for even more information.

Laser-Drilling Applications Google Scholar Results

noreply@blogger.com (Liesl M Heerdt) — Thu, 09 Jun 2011 20:41:00 +0000

We are doing a lot this year in anticipation of our 2nd International Light Seminar in October as well as in commemoration of this our 30th anniversary.

We decided that we wanted to get a better handle on where our parts have gone and how they are being used. I have already gone through Lenox Laser in space with NASA here. Now I want to take it back down to Earth.

In order see where our parts have been used and cited, I went to Google Scholar
and searched for "Lenox Laser." Here is the link to the results: Google Scholar. What I found was fascinating.

While not all of the results are accessible, those that are provide key insights into laser-drilling applications. The three broad categories are articles, patents, and theses and dissertations. In my research, I have broken them down accordingly and ordered them chronologically by publication year. The following graph illustrates the results:


click on the picture to enlarge

Here one can see a snapshot of Lenox Laser and how we are increasingly in demand. This also illustrates how laser-drilling and nano technologies have been growing.

I, and a few others, will be going through all of the articles we can and blog about them. We will give a summary of the article and the field that it relates to. However the key will be what part or parts we made and the applications.

We are working on improving our Newsroom on our company website. It will have a page where all the articles in which we are cited will be listed, as well as direct links. That will be up and running very soon.

So for now, please peruse through the Google Scholar results. You can even add keywords to specify your search, such as aperture or orifice. And, as always, please visit our website for more about Lenox Laser's products and services.

Use of SiC in a High Power Spatial Filter for Stray Light Reduction

noreply@blogger.com (Lenox Laser Inc.) — Wed, 08 Jun 2011 18:17:00 +0000

Thomson scattering measurement of the electron temperature and density profiles in high temperature plasmas is a well established experimental technique. The existence of high levels of laser-line radiation (“stray laser light”) in the detected scattered light signal can lead to difficulty in system calibration.

Spatial filtering is a standard technique for improving the spatial profile of low-power laser beams. Focusing a beam through a pinhole aperture allows removal of spatial irregularities caused by nonlinear effects of amplification, dust or imperfect optics.

     Silicon carbide is often used as an aperture material due to its high damage threshold.
Lenox Laser, Inc. of Glen Arm, Maryland, has laser drilled 210 micron apertures in SiC disks for such applications as stated above. Experiments have shown that SiC apertures perform better than copper apertures. It was found that the steady state stray light level for SiC was significantly less than for Cu.  Thus a silicon carbide aperture performed better than copper for irradiance at the spatial filter focus.
