CVI Melles Griot PR1‑1319‑99‑1025 Partial Reflecting Laser Mirror

CVI Melles Griot PR1‑1319‑99‑1025 Partial Reflecting Laser Mirror

• PR1 — High‑energy partial reflecting laser mirror series. These are dielectric mirrors designed to reflect a specific percentage of laser light at a given wavelength.

• The middle portion 1319 very likely indicates the design wavelength — in this case 1319 nm, a common Nd:YAG laser line (like the 1319 nm transition).

• 99 typically indicates the reflectance specification — e.g., ~99 % reflectivity at that wavelength.

• 1025 is the size code format indicating a ~25.4 mm diameter mirror (size code 1025 means 1.0″ diameter × appropriate thickness).

🧠 Typical Applications

• Laser resonator output coupling or intracavity elements (partial reflectors).

• Beam sampling or monitoring at 1319 nm (common in Nd:YAG systems).

• High‑energy laser optics where precise reflectance and surface quality are critical.
