CVI PR1‑1047‑90‑1025 Partial Reflecting Laser Mirror

CVI PR1‑1047‑90‑1025 Partial Reflecting Laser Mirror

• PR1 = Partial reflector / laser line mirror series used for splitting or sampling laser beams.

• 1047 = Center wavelength around 1047 nm (near‑infrared).

• 90 = Approximate reflectivity of 90% at that wavelength.

• 1025 = Size code, meaning 25.4 mm diameter × 6.35 mm thickness optical element (standard 1″ optic size).

So this part is a 25.4 mm diameter PR1 partial reflector mirror designed to reflect about 90 % of incident laser light at ~1047 nm (with the rest transmitted), typically used in laser systems for beam sampling or routing.
