Edmund Optics (EO), the premier provider of optical components, announces a collaboration with II-VI Incorporated to provide immediate delivery of zinc selenide optical components. ZnSe plano-convex (PCX) lenses, aspheric lenses, CO2 beam expanders, and lens stress analyzers are now available.

This collaboration makes it easier than ever before to purchase optical components for infrared applications throughout the design, prototyping, and production project cycles.

Techspec zinc selenide plano-convex (PCX) lenses are designed by EO and manufactured by II-VI out of premier grade ZnSe material with <0.0005 cm-1 bulk absorption at 10.6 µm. They are available uncoated or coated with broadband anti-reflection coatings for 8 – 12 µm or 3 – 12 µm. Their irregularity of < λ/20 at 10.6 µm and surface roughness of <50 Å makes them ideal for precision IR applications.

Similarly, the Techspec ZnSe aspheric lenses are also designed by EO and manufactured out of the same premier grade ZnSe. While offering the same surface specifications and 8 – 12 µm AR coating option as the ZnSe PCX lenses, the Techspec ZnSe aspheric lenses feature diffraction-limited performance for minimum focused spot sizes.

The CO2 beam expanders are constructed out of more premier grade ZnSe optical elements for collimating and improving the energy distribution of high power CO2 laser beams at 10.6 µm. The beam expanders feature minimized beam deviation and AR coatings that result in 99.4 % transmission and <0.1 % absorbance per surface at 10.6 µm.

The final new II-VI product offered by EO are lens stress analyzers which utilize cross polarization to identify mechanical stress, thermal stress, and contamination. They are available in either a portable, clip-on design or a bench-top model, ideal for lab settings. (Source: EO)
