CVI PR1-1319-90-1025 Partial Reflecting Laser Mirror

CVI PR1-1319-90-1025 is a partial-reflecting laser mirror manufactured by CVI Laser Optics / Melles Griot. It belongs to the PR1 series of high-energy partial reflectors, designed to reflect a specific percentage of light at a particular laser wavelength.

🧪 Key Specs Breakdown

• Type: Partial-reflective laser mirror (flat / plate optic) — used to split or sample laser beams.

• Series: PR1 (high-energy partial reflectors).

• Wavelength: 1319 nm — optimized for infrared lasers at that wavelength (common in certain solid-state lasers such as Nd:YLF or Nd:YAG at 1319 nm).

• Reflectivity: ~90% reflectance at the design wavelength — meaning ~90% of incoming light is reflected and the rest is transmitted.

• Size Code: 1025 — indicates a ~25.4 mm (1″) diameter optic, typical for this product line.

• Substrate / Coating: Typically a laser-grade glass (like fused silica or N-BK7) with a dielectric coating optimized for the specified wavelength.

🧠 Typical Uses

This type of mirror is used in laser cavities and optical setups for:

• Output coupling (letting a portion of the laser beam exit a resonator).

• Beam sampling or beam diagnostics (picking off a known percentage of the beam).

• Beam routing and alignment in research or industrial laser systems.
