New Breakthroughs in Metallic Glass and Laser Glass Drilling

In Live Science, there is a new article entitled "Bizarre Properties of Glass Revealed". It is about the new “breakthrough discovery in the bizarre properties of glass, which behaves at times like both a solid and a liquid.” The article can be found at http://www.livescience.com/technology/080623-glass-wings.html

Royall said, “knowing the structure formed by atoms as a glass cools represents a major breakthrough in the understanding of meta-stable materials and will allow further development of new strong yet light materials called metallic glasses. This stuff is generally shiny black in color, not transparent, due to having a lot of free electrons (think of mercury in an old thermometer).”

Lenox Laser, Inc. has also been a pioneer in developing advancements in glass processing. Our engineers were some of the first to successfully drill microholes in different types of glass accurately. Lenox Laser will also be a pioneer in the new field of metallic glasses that are currently being developed. These new glass types, mixed with exotic metals and materials, can revolutionize the optical, medical, biotechnology, space, semiconductor processing and scientific fields. Lenox Laser will be at the forefront of drilling the smallest microholes, apertures, orifices and arrays into these materials without the known risks of glass.

Lenox Laser is the premier microhole, aperture, and orifice glass driller in the industry. Our engineers can produce an aperture/orifice down to 5 microns. We mainly process the industry standard borosilicate glass, including the popular D263, but we have also processed quartz/fused silica, Pyrex variations, and soda-lime glasses. We specialize in drilling medical syringes, ampules, and vials for sophisticated leak detection systems, as well as drilling complex custom arrays in a variety of glass substrates. In addition, we have a complete line of standard glass products. Our list of customers includes many of the most recognizable names in the world, including government, university and private sector clients.

Free Online Critical Flow Orifice Calculator

Lenox Laser has been a pioneer and a leader in the critical flow orifice field for over 20 years. Customers have had orifices custom sized, drilled, and calibrated for them in various flow components in order to meet complicated and critical needs. We are able to eliminate the need for expensive and complicated mass flow controllers with our easy to use, inline, consistent, and cost-effective orifice technologies. A Lenox Laser calibrated orifice will produce consistent and repeatable flow rates of gas and liquids time and time again.

Lenox Laser has also created easy to use Orifice Sizing Calculator which has aided thousands of customers determine their orifice size for their flow control application. The calculator uses our flow control mathematics formulas which can be found in detail here. Our free online calculator can determine an orifice size using the following input values:

Inlet Pressure - PSIA, PSIG, Inches Mercury Absolute, Inches Water Absolute, Barr, Torr, Atmosphere, Kilopascals

Outlet Pressure - PSIA, PSIG, Inches Mercury Absolute, Inches Water Absolute, Barr, Torr, Atmosphere, Kilopascals

Gas Type - Air, Acetylene, Ammonia, Argon, Carbon Dioxide, Carbon Monoxide, Ethylene, Helium, Hexahydrochloride, Hydrochloric Acid, Hydrogen, Methane, Methyl Chloride, Nitrogen, Nitric Oxide, Nitrous Oxide, Oxygen, Sulfur Dioxide

Temperature - Fahrenheit, Celsius, Kelvin

Flow Rate - std cubic cm/sec, std cubic cm/min, std cubic cm/hr, std cubic ft/sec, std cubic ft/min, std cubic ft/hr, std gal/sec, std gal/min, std gal/hr, std liters/sec, std liters/min, std liters/hr, std pounds/sec, std pounds/min, std pounds/hr, std grams/sec, std grams/min, std grams/hr

Hole Units - Microns, Inches

The calculator will then display the appropriate hole size which Lenox Laser will be able to drill, calibrate, and certify your flow rate for your specific application in almsot any type of disc, VCR Gasket, Gland, Conflat, Barb/Luer, Nipple, Set/Hex Screws, and High Pressure or High Temperature Tubing. Custom parts and materials are also available for drilling with a setup fee.

Small Hole Applications

FlowThe small hole, orifice or aperture is the key element of any device or instrument designed to control or measure the flow rate of a gas or liquid. In the recent past, the gasoline piston engine went through a transition that improved performance and reliability. Precision made small holes brought to life the fuel-injection process, an important technology that has superseded the carburetor. For general applications, precision, fixed control of gas flow rate is made possible through placement of a small hole in the flow passage. Under fixed positive pressure conditions, the small hole becomes the flow rate calibration device. In the area of high vacuum helium leak detector calibration devices, the small holes provides the calibrated leak rate.

SemiconductorIntegrated circuits and other semiconductor devices are the foundation of today's electronics industry. The development and production of semiconductor devices and manufacturing equipment bases heavily on ion or molecular beam processing technology. Ion beam drilling devices require the use of small, precise holes for beam forming.

OpticalFrom early days, optics used small holes to illustrate the wave property of light. An annular diffraction pattern of interference fringes may be observed from the passage of light through a small hole. Small holes provide important functions in optical transfer assemblies. They provide the means for beam alignment, spatial filtering, aperture limiting, image analysis, and image processing.

Electron BeamA mask containing an array of small holes is used to control the electron beam emission in the color television picture tube. The electron microscope uses apertures as small as 2 microns in diameter to maximize control of electron beam emissions and profiling.
