Product Description

Meniscus ZnSe lens for Co2 laser

Zinc Selenide Window components are primarily used for transmissive optics and suitable for matching with photodiodes. Optical Germanium Windows are made exclusively with high quality" laser grade" material that can be used even in the kW range. When coated, these zinc selenide elements have a transmittance of T> 99.5 % at 10.6 µm.

According to shape we could divide into Plano Convex Cylindrical Lens, Meniscus Lenses, Plano Concave Cylindrical Lens

Meniscus Lenses

Meniscus lenses are generally used as cutting lenses. Optical Windows have a convex/concave surface by which the relevant aberration – the spherical aberration – is reduced. The achievable focus diameter is smaller than that of plano-convex/plano-concave lenses, particularly at short focal lengths. Because the lenses typically serve as the endpoint of the excess pressure region in a cutting head, the required edge thickness and the resulting maximum pressure load must be increased as necessary. For this reason, we differentiate between normal pressure and high pressure lenses.

PCX/PCV Lenses

Because of Optical Laser Lens shape, plano-convex/plano-concave lenses are easy to produce. Together a planar and a curved surface produce the required refractive power of a lens.

In many applications, in particular at long focal lengths, these lenses can be used without a problem. However, the shorter the focal length or the larger the beam diameter, the greater the spherical aberration. Then meniscus lenses are preferred.

Biconex/Biconcave Lenses

Biconvex/biconcave lenses have two equally curved surfaces and are used in rare cases at short focal lengths.

All lenses are only available custom made.

Feature and Applications:

ZnSe is insoluble in water, but reacts with acids to form toxic hydrogen selenide gas.

ZnSe is used to form II-VI light-emitting diodes and diode lasers. It emits blue light.

Optical Zinc Window is used as an infrared optical material with a remarkably wide transmission wavelength range (0.45 µm to 21.5 µm[2]). The refractive index is about 2.67 at 550 nm (green), and about 2.40 at 10.6 µm (LWIR)
