Zinc Selenide (ZnSe) Components e-mail for custom quote: sales@dmphotonics.com

Zinc Selenide (ZnSe) is the most popular material for infrared application. Due to very wide transmission range covering 0.6 to 20 micron CVD grown ZnSe high optical quality material is used to manufacture optical components (windows, mirrors, lenses etc.) for high power IR lasers.

Zinc Selenide custom made windows, lenses, Brewster windows, mirrors, beamsplitters and other components are available on request.

Del Mar Photonics offer a range of competitively priced UHV viewports , Conflat, ISO or KF including a variety of coatings to enhance performance.

Del Mar Photonics viewports are manufactured using advanced techniques for control of special and critical processes, including 100 percent helium leak testing and x-ray measurements for metallization control.

Windows Materials include:
Fused silica, Quartz , Sapphire , MgF2, BaF2, CaF2, ZnSe, ZnS, Ge, Si, Pyrex
Coating - a range of custom coatings can applied - which include
- Single QWOT
- Broad Band AR
- V coatings
- ITO
- DLC (Diamond like coating)


Zinc selenide most obvious and important advantage over other materials is its low absorption in the red end of the visible spectrum. This allows the ubiquitous helium neon laser to be used as a convenient and inexpensive alignment or sighting tool for infrared laser beams. Prealignment of optics may be necessary merely because the infrared beam is invisible to the eye, or in addition because the infrared laser beam is of such a high energy misdirected laser beam can be extremely dangerous to equipment or personnel.

Although zinc selenide has this clear advantage over silicon and germanium, unfortunately it is not an easy material from which to produce optics. Firstly, it is not a naturally occurring material and has to be synthesized using a difficult process (CVD). Secondly, the dust, which is generated when zinc selenide is ground and polished constitutes a significant health hazard as a cumulative toxin. Also, it is not a particularly hard substance and scratches easily.

whoa those are some big ZnSE optics (and dreads!?) ZnSe dust, don't breath this! (ala will it blend). Thanks again for some cool science video, please keep it up!

Wow. That's a giant ZnSe window!
