Techspec IR achromatic lenses

Edmund Optics has introduced its new Techspec line of infrared achromatic lenses, designed to provide near diffraction-limited focusing performance over their full spectral range. The lenses are colour corrected for 3-5µm (mid-IR) or 8-12µm (long-IR) and are available in 30mm diameter with focal lengths of 40, 50, 60 and 75 mm. The precision optical grade crystalline lenses are air-spaced and aligned within an anodised aluminium barrel. All lenses are coated for maximum energy throughput over their specified spectral region.

The lenses are well suited to applications in FTIR spectroscopy, thermal imaging and for use with tunable QCL and other infrared lasers. The new lenses offer significantly improved performance when compared to traditional singlets, allowing designers in industrial, medical, scientific and military applications to utilise the entire dynamic range and full quantum efficiency of their infrared sensors for an impressive array of diverse OEM and laboratory uses.
