October 27, 2010 - Edmund Optics introduces TECHSPEC Germanium Infrared (IR) Aspheric Lenses, which are available in standard and hybrid configurations. Hybrid Lenses are color corrected for 3-5 µm. TECHSPEC Germanium IR Hybrid Aspheric Lenses provide diffraction limited focusing performance at any wavelength over the 3-5 µm region and near diffraction limited performance when used over the entire 3-5 µm range. Color corrected for 3-5 µm, each hybrid aspheric lens is coated for greater than 95% transmission and less than 0.5% reflection at 3-5 µm, offering excellent efficiency and reduced costs of IR illumination. The hybrid aspheric lenses are ideally suited for integration into imaging applications, FTIR spectrometers, or any mid-wave IR application using a broadband light source. The versatile lenses are offered in a 25 mm diameter with focal lengths ranging from 12.5 mm to 100 mm, with custom designs and coating options available upon request.Standard Lenses designed for Mid- and Long-Wave IR regions TECHSPEC Germanium IR Aspheric Lenses, available with a variety of coating options, provide diffraction limited focusing performance over a broad spectral range in the Mid- and Long-Wave IR regions. Each of the aspheric lenses is available uncoated or with BBAR coating options for greatest flexibility. As uncoated germanium has a transmission of less than 50%, users should consider adding custom anti-reflective (AR) coatings when specifying an uncoated lens. Every BBAR coated lens features greater than 95% transmission and less than 0.5% reflection, which is ideal for integration into a wide variety of diverse OEM applications. Standard Germanium IR Aspheric Lenses are available in a 25 mm diameter size, with focal lengths ranging from 12.5 mm to 75 mm, in uncoated, 3-5 µm coating and 8-12 µm coating versions. These lenses are ideal for monochromatic light sources such as quantum cascade lasers and offer a high performance alternative to standard plano-convex lenses.Full prescription data is available for both TECHSPEC Germanium IR Standard and Hybrid Aspheric Lenses. EO's TECHSPEC Germanium IR Aspheric Lenses and TECHSPEC Germanium IR Hybrid Aspheric Lenses are in-stock and available for immediate delivery for fast turnaround and excellent value.
