Zerodur precision broadband mirrors offer durable all dielectric coatings designed for popular applications such as spectroscopy, microscopy, and general laboratory applications.
RS, avg>99% @ 488-694 nm or 700-950 nm
Substrate flatness & surface quality λ/10, 20-10 to λ/20, 10-2
Available in diameter from 25.4 mm to 152.4 mm
Zerodur substrates for minimum thermal distortion
Best suited for spectroscopy, microscopy and general laboratory use
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.
Visible Broadband Dielectric Coating
Our BD.1 visible broadband dielectric coating reflects all visible laser lines in the range of 488 to 694 nm with greater than 99% efficiency for s-polarization and 98% for p-polarization at 0 - 45° angle of incidence.
NIR Broadband Dielectric Coating
Our BD.2 coating offers high reflectance for near infrared diode laser applications. Reflectivity is greater than 99% for s-polarization and 97% for p-polarization from 700 – 950 nm at 0 – 45° angle of incidence. Greater than 80% average reflectivity at 632.8 nm is also provided to permit easy alignment using a HeNe laser.
Select the Specification Level Required
Newport offers a choice of substrates to match your requirements. When preservation of wavefront and low scatter is critical, consider our 1-, 2-, and 3-inch mirrors with λ/20 flatness and 10-2 scratch-dig. For less demanding applications, our λ/10, 15-5 substrates provide excellent performance at a lower cost. 4-inch and 6-inch mirrors are also offered as standard dielectric mirrors.
