CVI Melles Griot PR1-1319-80-1025 Laser Optical Mirror

CVI Melles Griot PR1-1319-80-1025 Laser Optical Mirror

• PR1 — Partial reflecting mirror series (used for beam sampling, pick‑off mirrors, etc.)

• 1319 — Center wavelength around 1319 nm, a common infrared laser wavelength (e.g., Nd:YAG third harmonic or other IR lasers)

• 80 — Approximate reflectance percentage (≈ 80% reflective)

• 1025 — Diameter ~25.4 mm (standard CVI part number suffix indicating 1‑inch optics)

• Typically high‑quality optical substrate like fused silica with precision coating suitable for laser use (low scatter, high damage threshold).

These mirrors are typically used to pick off part of a laser beam while transmitting the rest, for diagnostic or alignment purposes in laser systems.
