ZnSe Plankonkave Linse 30mm Durchmesser -50mm Brennweite

SLZS-30-50NCO2

Diese sphärischen Einzellinsen bestehen aus Zinkselenid. Im Gegensatz zu anderen optischen Materialien für Infrarotwellenlängen wie Ge (Germanium) oder Si (Silizium) übertragen ZnSe-Linsen etwas sichtbares Licht, wodurch die optische Achseneinstellung (Ausrichtung) von Infrarotlasersystemen mit kostengünstigeren He-Ne-Lasern erleichtert wird. Linsen zur Verwendung mit CO2-Lasern haben eine AR-Beschichtung.
◦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.

Important: Treatment of ZnSe optics
ZnSe (Zinc selenide) is Poisonous and harmful substance classified as legal, depending on the specifications, the certificate of delivery may be required for acquisition of Poisonous and harmful substances. In addition, ZnSe Optics disposal after use is prohibited in general.
Lenses that are no longer needed, please return it to us.

However, we only take back products that we supplied. This policy noted is in Japan and other countries may differ in the treatment of ZnSe (Zinc selenide), please contact your local sales office.

Leitfaden
  • For other focal length and diameter size not listed on the website or in our current catalog, please contact our Sales Division with your request.
Achtung
  • 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.
