We offer two standard coatings for the visible and NIR, with 0–45° angle of incidence. These mirrors are available in sizes from 12.7–203.2 mm (0.5–8.0 in.) with Pyrex® or Zerodur® substrates and in two elliptical sizes with Pyrex substrates. • Best general purpose broadband high reflectors • Rs, Rp >99% for 488–694 nm, or... • Rs >99%, Rp >98% for 700–950 nm • Over 35 types of substrates to choose from Please see page 520 for information on our economical VALUMAX® broadband dielectric mirrors.
