產品特色Features
Introducing YBE beamexpanders. Designed for low power (500W) laser such as Nd:YAG and Yb doped fibre lasers operating near the 1μm wavelength.
The beamexpanders are of Galilean design and use Multi-spectral Zinc Sulphide for the optics which has an absorbption at 1μm of 0.0005cm−1 (similar to ZnSe at 10.6μm).
ZnS also has 20 times the thermal conductivity of Fused Silica and a higher refractive index. The refractive index allows a two element design to be used rather than three elements.
