CVI PR1-1120-70-1025 Partial Reflecting Laser Mirror

CVI PR1-1120-70-1025 Partial Reflecting Laser Mirror

• PR1 → product family: High energy partial‑reflecting laser mirror (dielectric coating)

• 1120 → Wavelength or wavelength center (often design wavelength around ~1120 nm). Many CVI PR1 parts use center wavelengths like “1064,” “1030,” etc., so this likely indicates the design wavelength of the coating.

• 70 → Reflectivity (~70 % reflectance at that wavelength). PR1 optics often have reflectivities in tens of percent for partial reflection.

• 1025 → Substrate code (size) — for CVI optics, “1025” commonly means a 25.4 mm (1.0 in) diameter substrate.
