Lake Shore Cryotronics to launch new band pass filters at SPIE Defense, Security and Sensing Conference 2012
Band Pass Filter Applications

Lake Shore Cryotronics announces that it will be launching its new BPF series of terahertz (THz) and infrared (IR) band pass filters at the SPIE Defense, Security and Sensing Conference, from April 23-27, 2012 at the Baltimore Convention Center, in Baltimore, MD, Booth #321.

Lake Shore scientist Dr. Bill McGovern will present a paper on metal-mesh filters, in the Photonics for Space Applications 1 session, April 23rd at 9:50 a.m. The paper (8385-4) focuses on applications for missile defense, astronomy, IR, and THz spectroscopy.

Lake Shore will feature the BPF series of THz and IR band pass filters that were originally developed for NASA. These new filters are precision-built, stable over a wide temperature range, and immune to radiation, making them ideal for use in THz and millimeter wave imaging/security, ground and airborne-based astronomy, cryo-cooled astrophysics detectors, and general electro-optic research. Other common applications include THz and Fourier transform infrared (FTIR) spectroscopy and materials characterization, as well as THz device characterization and testing.

The BPF series includes more than 100 off-the-shelf filter models that cover more than 25 pass bands and 4 different aperture sizes. These standard products, designed and manufactured by Lake Shore in the USA, are cost-effective and readily available without restriction for general applications, with only a stock-to-2-week lead time, and are well suited for classified domestic programs.

Dr. McGovern’s presentation, “Metal-Mesh Optical Filter Technology for Mid-IR, Far-IR and Submillimeter,” will present data on vibration-tolerant, launch-capable, high-transmission, radiation-hard filters, operating at cryogenic temperatures.
