Lenox Laser’s High-Power Aperture Mount

Blog

When working with optical apertures, it is essential to maintain the utility and longevity of those tools. Spatial filtering of a high-energy laser beam is a non-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 HEA-100C high-energy aperture mount that uses the combination of reflecting and heat-dissipating parts to reduce the energy density that reaches the aperture by a few orders of magnitude. Our team worked meticulously and thoroughly to ensure that not only the utmost quality was given to the product but also a long-lasting lifespan. This process includes rigorous testing and configuration of different scenarios that meet our impeccable standard of excellence. This method significantly extends the lifetime of the optical aperture. Our engineering team selected the HEA-100C dimensions to fit most optomechanical mounts designed for one-inch mirrors or lenses provided by leading manufacturers; namely CVI-Melles Griot, Newport, New Focus, Thorlabs, Edmund Optics, etcetera. Our mounts can mount any aperture. When done so, they become an integrative part of the existing optical layout or device. The mounts also do not require any additional adaptors.

Our quality, high-powered apertures can also complement our mounts. The apertures — made in various materials — are used for things like Q switching and laser balance and flow. If you would like to know more about our apertures, check out our vast product range.

As always, Lenox Laser thanks our readers for taking the time to read about our exciting endeavors every week. Please contact us at any time, and we will happily assist you.

NASA Kepler Mission: Update

NewsUncategorized

The NASA Kepler mission is currently in its second phase of operation since the recovery of the craft and launch of K2. A couple of years ago Kepler lost some important technology and had to return to Earth, but now with K2 being launched, the campaigns can continue.
The mission still retains its original goal of discovering earth-like planets and determining if any are habitable.
Lenox Laser was responsible for fabricating what the scientists over at NASA call the Starfield Plate. This plate consists of stainless steel laser drilled with an array of holes as small as 3 microns in diameter with the purpose of performing photometry.

Lenox Laser Pioneering New High-Powered Laser Technologies

Blog
“The high power laser parameters relevant to selecting an aperture suitable for use in the optical beam delivery system are aperture substrate material, laser power or energy, area and time.”



– Gilbert R. Smith, P. F.

 

The development of high power lasers includes but is not limited to the following methods: Q-switching, cavity-dumping, and mode locking. In these cases, lasers operate in a pulsed regime when the single pulse or package of pulses is generated at a certain timing rate.



 

 

High energy and high power apertures are intended to be used in the optical transfer assembly using a large laser as a source. The parameters such as laser power and pulse energy, pulse duration and repetition rate become important.

Small Hole Applications

Blog

The 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.

Semiconductor Integrated 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.

Optical from 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 Beam, a 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.
