These laser line mirrors are highly efficient reflectors optimized for a narrow wavelength range. Each achieves greater than 99% reflectance, from 0-45° angle of incidence, for any polarization. The Zerodur substrate offers a nominally zero thermal expansion.
Durable dielectric laser line coatings from VIS to NIR
Zerodur® is a unique glass-ceramic material with a nearly zero coefficient of thermal expansion and excellent homogeneity of this coefficient throughout its entire piece. It is the best choice when extreme thermal stability is required or for environments with large temperature fluctuations. For more information, please see our Optical Materials technical note.
