Features

Quality Zerodur Substrates Provide Thermal Advantage

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. Thus, Zerodur mirror substrates are the best choice when extreme thermal stability is required or for environments with large temperature fluctuations. Also, Zerodur's high stability can be critical for applications requiring diffraction limited performance. (Note that Zerodur should not be used for transmissive optics due to poor index homogeneity for the material.) For more information on optical materials, 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.
