Tighter Tolerances for Flow Control Components

At an ever increasing rate industry is requiring tighter tolerances on flow control components.  As a supplier of laser drilled orifices in a variety of components, Lenox Laser, Inc. has been meeting these tighter tolerance requirements for several years.  Incidentally, these very tight toleranced parts have been in high demand.  To accommodate this demand, Lenox Laser has developed proprietary processes that allow tolerances to be consistently held.  Tolerances can be as tight as +/-0.5% and +/-1% on a 10 micron or larger hole sizes.  Compare this to standard tolerances that typically range from +/-5% and larger with respect to the hole size (i.e. a 1 micron hole can have a standard tolerance of close to +/-50% depending upon the part material and thickness).  Often customers may need not just tighter tolerances on a nominal size but matched sets or pairs with tolerances of +/-1-2% of each other.  Integration of the laser process with its flow testing capabilities ensures repeatable results with higher yields.  Very tight tolerances can be held on most standard flow components we offer, as well as, customer supplied parts.  Visit our website at www.lenoxlaser.com or email sales@lenoxlaser.com for more information.

Microlensing

The Lenox Laser Corporation of Glen Arm, MD, hosted a seminar that featured a wide range of topics in the field of light and optics. One of the topics of great interest was "microlensing". Go to the following web address for a great article about this very intriguing subject.

Metrology Automatic Measuring

Lenox Laser has recently purchased a smartscope FLASH metrology system.
The machine will automatically measure down to a three micron aperture.
We also offer quality reports as an additional service.
Optical Gauging Products,Inc, is one of the leaders in field of metrology.
Our Smartscope Flash 200 Video Inspection System is a great asset to our quality assurance program.

PicoLaser Drilled Nanometer Holes for the Semiconductor Industry

Lenox Laser is introducing a series of flow calibrated nanometer holes to the semiconductor industry in tungsten, 304 stainless, nickel; gaskets and fittings. The process of picosecond laser drilling is a recent development with new solid state UV lasers. Lenox Laser has designed systems for the purpose of drilling cleaner and smaller holes with closer tolerances. This process has also given us the ability to generate more precise micro flow rates with tolerances that have exceeded our expectations.

Process Development

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.

High Energy Aperture Holder (MT-1, MT-1R)

Spatial filtering of a high energy laser beam is not a trivial problem when the energy density of the focused beam approaches the ablation threshold of the optical aperture material.
Materials with a high ablation threshold have very low thermal conductivity; thus, depending upon the repetition rate of laser pulses, can become subject to melting proceeded by aperture damage.
The Lenox Laser Corporation has developed the MT-1R high energy aperture holder that uses the combination of reflecting and heat dissipating parts to reduce by a few orders of magnitude the energy density that reaches the aperture. This method significantly extends the lifetime of the optical aperture. The MT-1R dimensions were selected in order to fit most of the optomechanical mounts designed for one inch mirrors or lenses provided by leading manufacturers, namely CVI-Melles Griot, Newport, New Focus, Thorlabs, Edmund Optics, etc.
When MT-1R is mounted in one of the above mentioned mounts it becomes an integrative part of the existing optical layout or device and does not require any additional adaptors.

Slit Solutions

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 5x8 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 5x8 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.
