New IR and UV Optics to Minimize Loss and Dispersion

TECHSPEC® Calcium Fluoride CaF2 Aspheric Lenses
(PresseBox) ( Mainz, )
Edmund Optics® (EO), a renowned provider of optical components, continuously expands its product offering to reflect market developments and customer needs. New products are added each month to better serve the industry. EO has released Zinc Selenide (ZnSe) Wedged Windows, which are ideal for infrared (IR) applications, and TECHSPEC® Calcium Fluoride (CaF2) Aspheric Lenses, which have high transmission from ultraviolet (UV) to IR wavelengths.

Zinc Selenide (ZnSe) Wedged Windows are designed for use with high power CO2 laser systems. These windows are available in two wedge angle options: 30 arcmin or 3°, which help to eliminate etalon fringe effects as well as to prevent cavity feedback. With a broad wavelength range, excellent transmission in the IR, low absorption, and high resistance to thermal shock, Zinc Selenide (ZnSe) Wedged Windows are ideal for IR applications including thermal imaging, forward-looking infrared (FLIR), and medical imaging.

TECHSPEC® Calcium Fluoride (CaF2) Aspheric Lenses have high transmission from 200 nm (UV) to 7 μm (IR). The low refractive index of calcium fluoride reduces Fresnel reflection loss without the use of anti-reflection (AR) coatings. Low solubility and a hardness that is superior to other fluoride-based substrates enables these diamond-turned aspheres to be used in harsh environments. Two designs for these aspheres are available. The first features a design wavelength of 266 nm for use with Nd:YAG and excimer lasers, as well as for use in other UV applications. The second design features a 4 μm design wavelength for use in other spectroscopic, mid-wave IR (MWIR) thermal imaging, and other IR applications.
