BARRINGTON, N.J., Feb. 7, 2011 — Providing near-diffraction-limited focusing over their full spectral range, Edmund Optics Inc.’s TechSpec infrared achromatic lenses are color-corrected for 3 to 5 µm (mid-wavelength infrared) or 8 to 12 µm (long-wavelength infrared) and are available with a 30-mm diameter with focal lengths of 40, 50, 60 and 75 mm. The lenses are suited for applications in Fourier transform infrared spectroscopy, thermal imaging and for use with tunable quantum cascade and other infrared lasers. They offer significantly improved performance when compared to traditional singlets, according to the company, allowing designers in industrial, medical, scientific and military applications to use the entire dynamic range and full quantum efficiency of their infrared sensors for a variety of OEM and laboratory uses. They feature precision optical-grade crystalline lenses, air-spaced and expertly aligned within an anodized aluminum barrel. All lenses are coated for maximum energy throughput over their full specified spectral region. Complete prescription data is available upon request, and the lenses are in-stock and available for immediate delivery.
