Dielectric mirror TS-08 series

squarerectangularfront-surface

Product overview
Aluminized surface mirrors feature an aluminum reflective coating applied to one side to reflect images and light. Two standard protective overcoats are offered: SiO and MgF2. Compared with MgF2, SiO absorbs in the ultraviolet region and has slightly lower reflectance, but it can be deposited at lower temperature and is more cost-effective. Custom materials, coatings and dimensions are available on request.
