BARRINGTON, N.J., June 7, 2010 — Edmund Optics Inc. has introduced its new TechSpec mid-wave IR achromatic lenses that deliver near-diffraction-limited performance over their entire spectral range. They are suitable components for use by designers and researchers working in the 3- to 5-µm spectral region. Applications include Fourier transform infrared, spectroscopy, mid-wavelength infrared (MWIR) thermal imaging and for use with tunable quantum cascade lasers. The company says that the lenses provide significantly improved performance over comparable singlets, providing a much smaller focused spot with more energy for higher resolution images or greater signal detection. This feature allows designers in industrial, medical, scientific and defense applications to use the full dynamic range and quantum efficiency in their mid-wave sensors. The new doublets feature precision germanium and silicon lenses that are air-spaced and aligned within a sturdy anodized aluminum barrel. The lenses are color-corrected and coated for maximum energy throughput over their full spectral range. They are available in four 30-mm-diameter versions with focal lengths of 40, 50, 60 and 75 mm. They are in-stock and available for immediate delivery.
