plano-concave dielectric laser mirror fused silica

Product Description

Precision Plano-Concave Dielectric High Reflector Laser Mirror – Laser Optics Inc.

This is a premium, custom laser optic from the renowned manufacturer Laser Optics Inc. (Danbury, CT). Designed for high-performance visible laser systems, it features a fused silica substrate for maximum damage resistance and thermal stability, making it ideal for demanding laboratory and industrial applications.

Key Specifications:

• Diameter: 4.08 inches (103.6 mm)

• Substrate: UV-Grade Fused Silica (high LIDT, low absorption, UV–NIR transmission)

• Radius of Curvature: 5 meters (concave side)

• Effective Focal Length: ≈2.5 meters

• Coating: Dielectric “MAX R” High Reflector (>99% typical)

• Optimized Wavelength: 459 nm (blue-violet, ideal for argon-ion laser lines)

• Back Side: Plano (flat) with frosted/ground finish to eliminate stray reflections

• Condition: Excellent – dielectric coating is clean with no visible scratches or damage

Optical Performance:

• High Damage Threshold: Fused silica substrate withstands high-power laser operation

• Low Aberration: Long 5m radius minimizes spherical aberration for precise beam control

• Stray Light Control: Frosted back surface prevents ghost reflections

Applications:

• Laser Cavities: High-reflector end mirror or output coupler for argon-ion, frequency-doubled, or other blue/violet laser systems

• Beam Steering & Folding: Long-radius concave mirror for expanding, collimating, or redirecting beams with minimal wavefront distortion

• Research & Spectroscopy: Pump laser alignment, resonator builds, or high-power visible/UV experiments

• Vintage Laser Restoration: Direct replacement or upgrade for systems using Laser Optics Inc. components
