Sigma Optics Infrared Window (ZnSe)

Zinc Selenide（ZnSe）It can be transmitted through visible light20MmThe crystal of infrared spectrum light.

usedZnSeInfrared window for crystals. can serve asCO2Laser（10.6Mm）Use the window.

Equipped with uncoated models with uniform infrared band transmittanceOPZS, and high transmittance anti reflection film modelsWZSA.

600nmThere is a certain transmittance near the wavelength, which can be indicated by visible light.

ZnSeCrystallization has almost no hygroscopicity and can be used similarly to ordinary optical components.

ZnSeCrystalline isotropy without birefringence phenomenon.

Important AboutZnSeOperation methods of material optics

ZnSeLegally classified as a highly toxic substance, uncoated product（OPZS）A certificate of transfer for highly toxic substances needs to be submitted.

Moreover, after useZnSeOptical components are prohibited from being disposed of as ordinary garbage.

information

▶ Additionally, it is available for useZnSeofCO2Laser lens（SLZS）.

W3074

▶ We also undertake the manufacturing of non catalog product sizes or wedge-shaped processing products.

Attention

▶ Exposure to strong acids can produce toxic hydrogen selenide. Please do not immerse the lens in solutions such as hydrochloric acid or sulfuric acid, or let the solution wet the lens.

▶ High energy laser beam focused onZnSeOn the surface, thermal decomposition produces toxic gases. Moreover, the intense conduction of laser heat can lead toZnSeDamage, generating a large amount of gas and dust. onceZnSeWhen the lens is damaged, be careful not to touch it with bare hands, do not inhale the steam or dust generated, and carefully recycle the fragments.

▶ Non coated type（OPZS）Due to the presence of reflections on both the front and back sides (each side)17%Therefore, the transmittance will be affected30％左右
