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.
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.
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.

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”.

Lenox Laser has made exciting breakthroughs in the manufacturing processes of exact leaks!
Exact Leaks are calibrated microholes that are repeatedly and reliably generated in packages and/or other pharmaceutical and manufacturing goods. These microholes are commonly used in integrity testing processes.
Lenox Laser’s new process allows the creation of 0.5 micron holes in a wide variety of materials; including plastics and metals.
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:
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.
Some of the most innovative companies in the DelMarVa area came together at Lenox Laser for a recent conference discussing the theme “Micro-to-Nano” technologies. The conference included talks on a range of topics, including Nanotechnology, Pharmaceutical research, Rapid Prototyping, and Laser Drilling.
John Bishop of Norsam Technologies addressed conference attendees on the topic of Ion Beam drilling. Visitors from Northrop Grumman and other local corporations reviewed digital presentations on Nanostructures, MEMS manufacturing, Advances in Laser Drilling, and Microlensing.
The wide overview of current techniques and new ideas provided an excellent forum for group discussions as innovators met manufacturers in this unique scientific environment. Lenox Laser plans to host future collaborative conferences focusing on subjects such as Rapid Prototyping and Micro-fluidics.
Ruling Out Multi-Order Interference in Quantum Mechanics

Quantum mechanics and gravitation are two pillars of modern physics. Despite their success in describing the physical world around us, they seem to be incompatible theories. There are suggestions that one of these theories must be generalized to achieve unification. For example, Born’s rule—one of the axioms of quantum mechanics—could be violated. Born’s rule predicts that quantum interference, as shown by a double-slit diffraction experiment, occurs from pairs of paths. A generalized version of quantum mechanics might allow multipath (i.e., higher-order) interference, thus leading to a deviation from the theory. We performed a three-slit experiment with photons and bounded the magnitude of three-path interference to less than 10–2 of the expected two-path interference,thus ruling out third- and higher-order interference and providinga bound on the accuracy of Born’s rule. Our experimentis consistent with the postulate both in semiclassical and quantumregimes.

The personal goal and commitment of each member of the Lenox Laser Corporation’s engineering team is to provide each customer with reliable and robust products made to specified custom requirements and conditions, such as, high energy light beam densities, aggressive chemical and biological environments, mechanical stresses and vibrations, aerospace and underwater uses, etc.
We have a wide range of tools at our disposal. Our lasers range from CW to picoseconds in pulse widths; from far IR to hard UV wavelengths; from Joules to micro-Joules in laser beam energy. We can drill to a specified gas or liquid flow or light intensity. We have a fully equipped machine shop and chemical etching capabilities. Our experienced staff can combine some or all of those capabilities in a multi-step process where a single technique application becomes impractical or impossible. In each unique case, the choice of product materials and manufacturing processes are specific and may affect future product performance.
Both our production and engineering teams are readily available to help customers to consider those specifics in the original product design. We may suggest developing and redesigning a product to create both a feasible and cost effective project.
Lenox Laser has a distinguished history of successful medical product development under the auspices of NIH grants enabling us to introduce innovative products to a highly competitive global market. We have pioneered and have become an industry standard in a metrology associated with holes drilled for leak detection in the medical, pharmaceutical, automobile and food industries.
Slits are widely used in a wide range of applications in both science and industry. Applications include (but are not limited to) measurement of the properties of light; calibration and separation of light flux; study of light interaction with materials and itself-proving concepts in quantum theory and many other applications.
The Lenox Laser Corporation is a leading manufacturer of micrometer slits made in most materials with very high quality precision and sharpness.
Lenox Laser has developed a new version of the optical slit cut in a precise 5×8 mm metallic foil that will solve the registration problem that normally takes place when slits are cut in 5/8″ (or other size) substrates. The orientation of the micro-slit is along the sides of a 5×8 mm rectangular substrate. In this case, one of the substrate edges can be used as the positioning feducial. This new geometry permits for angular registration with later rotation at any arbitrary angle of one or multiple inserts in a single holder with very high precision.
