Mirrors

Optosigma Mirrors are precision reflective optical elements designed for laser beam steering, interferometry, imaging, and general optical systems requiring controlled, low-scatter reflection with defined spectral performance. Optosigma manufactures mirrors in a wide range of substrate materials, coating types, sizes, and surface form factors to address the full spectrum of optical laboratory and OEM instrument applications.

Coating types available from Optosigma:
– Protected Aluminum: broadband reflectance from UV through near-IR (250-900 nm); protected overcoat prevents oxidation
– Protected Silver: higher reflectance in the visible and near-IR (400-2000 nm); ideal for broadband visible and NIR beam-steering
– Protected Gold: high reflectance in the NIR and mid-IR (above 600 nm, over 96% from 800 nm); standard for CO2 laser beam delivery
– Dielectric HR coatings: laser-line high-reflectance coatings (over 99.5% R at specified wavelength) for laser cavity mirrors and beam-steering at 355, 532, 1064 nm and other wavelengths

Surface quality is specified to ISO 10110 or MIL-PRF-13830 standards; surface flatness is specified in wavelengths (lambda/10, lambda/4) at 632.8 nm. Substrate materials include borosilicate glass (Bk7), fused silica (for UV and high-power laser applications), and Zerodur (zero thermal expansion).

Physical formats include flat circular and rectangular mirrors, right-angle prism mirrors, elliptical mirrors for 45-degree beam-steering, and off-axis parabolic mirrors for focusing or collimating without introducing spherical aberration.

NewRoad provides Optosigma mirrors in Israel for laser laboratories, optical system builders, and research institutions requiring precision reflective optics with traceable coating and surface specifications.
