Single Lens for CO2 Lasers / SLZS-30-50NCO2
These spherical single lenses are made of zinc selenide. In contrast to other optical materials for infrared wavelengths such as Ge (germanium) or Si (silicon), ZnSe lenses transmit some visible light, facilitating optical axis adjustment (alignment) of infrared laser systems using lower cost He-Ne lasers. Lenses intended for use with CO2 lasers have AR coatings.

◦High powered lasers often emit laser light in the infrared region. Such systems require careful handling, since infrared laser light is invisible. Because of this laser light, preliminary alignment of optical parts in many cases are essential. While zinc selenide transmit some light in the visible spectrum, it allows easier alignment of other optical components.

| Attention | ▶Hydrogen selenium is harmful when it comes in contact with strong acids! Do not immerse the lens in hydrochloric or sulphuric acid. ▶When light is condensed on the surface of ZnSe, the high power laser beam may produce toxic gases due to the thermal decomposition. In addition, a large amount of gas and powder occurs when the ZnSe lens is damaged by the laser thermal runaway. In case of the ZnSe lens is damaged by any chance, DO NOT handle the lens with your bare hands. Collect the debris and be careful not to inhale the powder and gas generated. ▶Please check the “wavelength characteristic of the focal length data” on “Technical Data” for the focal lengths of each wavelength. ▶There is a possibility that the spherical aberration will increase and optical performance of the system will be degraded if use in reverse. The focused spot may enlarge and the image will appear un-focused. |
