Elliptical Mirror, Broadband Dielectric, 33.02 x 46.7 mm, 488-694 nm

The 13E20BD.1 Broadband Dielectric Elliptical Mirror is an extremely versatile mirror for laboratory applications and highly efficient over a broad wavelength range. This 1.30 inch (33.02 mm) minor axis, 1.838 inch (46.70 mm) major axis, elliptical mirror is made from a 9.37 mm thick Borofloat® 33 substrate. Borofloat® 33 has low thermal expansion and is an excellent substrate for most applications. The BD-1 coating is extremely durable and will withstand repeated cleaning. This mirror has a λ/10 substrate surface flatness and a 15-5 surface quality.
