Quick Details
Specifications
hot sale Import 20mm Dia ZnSe Focus Lens for laser machine
Feature:
Ultra low absorption imported ZnSe Focus Lens
1. Ultra-low absorption, less heat
2. More stable Focusing spot, much faster cutting speed
3. Higher cost-efficiency, longer lifespan
Introduction
ZnSe has been made by means of import CVD from USA, and this material has low absorbance. The lens can can withstand high power density and the surface coating is solid , not easy to fall off and wipe-resistant. After AR-coating has been coated on double-side of imported ZnSe, the transmissivity of the wavelength 10.6um, which is commonly used in CO2 laser industry, can reach 99.5%. We have optimized the design from two sides - diffraction and aberration and have developed a series of products with the minimum actual focal spot diameter in the case of the same focal length. We can respectively design and produce the products according to different requirements of the customers for focus length, rear focus length, lens aperture, the diameter of the incident ray and so on.
Common processing requirements for the focus lenses.
Designed wavelength: 10.6um
Focus length tolerance: ±1%
Appearance tolerance: 0/-0.1mm
Thickness tolerance: ±0.1mm
