New aspheric molded lenses are designed for collimating light from MWIR and LWIR lasers, such as quantum cascade lasers (QCLs). Manufactured from Black Diamond chalcogenide glass, lenses have a high NA for maximum light collection. Antireflective coatings are available for the SWIR (1.8–3 mm), MWIR (3–5 mm), and the LWIR (7–12 mm) wavelength ranges.

Laser Collimating Lens for MWIR Quantum Cascade Laser

LightPath Technologies introduces a new addition to its family of collimating lenses for Quantum Cascade Lasers.

(January 19th, 2009) Orlando, FL. LightPath Technologies, Inc. (Nasdaq: LPTH - News), LightPath Technologies is introducing a new aspheric molded lens for collimating light from MWIR and LWIR lasers, such as quantum cascade lasers (QCL). This new lens extends the range of off-the-shelf collimating lenses for QCLs from LightPath.

This lens is manufactured from LightPath’s Black Diamond chalcogenide glass and has a high numerical aperture designed for maximum light collection from quantum cascade lasers. The molded glass aspheric design enables optical designers to take advantage of aspheric performance in the MWIR without having to design and build expensive custom diamond turned Germanium or Zinc Selenide lenses. The Anti-Reflective coatings are available for the SWIR (1.8mm – 3 mm ), MWIR (3 mm – 5 mm) and the LWIR (7 mm – 12 mm).

“LightPath Technologies is continuing to expand its traditional market for laser collimation lenses into the infrared with the introduction of this lens. This new lens will enable system designers to take advantage of quantum cascade lasers to address rapidly expanding markets such as the $1.2 billion Gas and Environmental Sensing equipment market, the $6 billion IR Countermeasure (IRCM) market, and $37 billion explosives detection systems market. ” said Jim Gaynor, CEO and President of LightPath.
