When used in etalons or optical cavities, these mirrors typically provide finesse levels in excess of 30,000 — approximately 30 times better than mirrors manufactured by standard techniques. To convert reflectivity (R) and transmission (T) to finesse (F) and efficiency (ç), with absorption (A): • Highest reflectivity and lowest losses of any commercially available mirrors • R >99.97% typical for high finesse mirrors • Optical loss <100 ppm • Superpolished to <1 Å rms microroughness Specifications Material UV grade fused silica Surface Figure, S1 Flat: ë/10 at 632.8 nm over central 80% clear aperture Concave: ë/8 irregularity at 632.8 nm over central 80% clear aperture Surface Roughness, S1 Super polished to <1 Å rms microroughness over central 50% of diameter Surface Quality, S1 0-0 scratch-dig inside central 12.7 mm diameter 20-10 scratch-dig outside central 12.7 mm diameter Coating, S1 SR.xxF High Finesse: Finesse F >10,000 (R >99.97%), Efficiency ç >10% (T <0.03%) over the wavelength range SR.xxT High Transmission: Finesse F >5,000 (R >99.94%), Efficiency ç >50% (T <0.06%) over the wavelength range Angle of Incidence 0° S2 Surface ë/10 at 632.8 nm over central 80% clear aperture Surface Quality, S2 20-10 scratch-dig Antireflection Coating, S2 Broadband, multilayer coating, Ravg <0.5% Diameter Tolerance +0/-0.1 mm Thickness Tolerance Flat: ±0.38 mm, Concave: ±0.13 mm Wedge 30 ±15 arc min (flat mirror only) Chamfers 0.50 ± 0.25 mm face width x 45° ±15° Durability MIL-C-675C, para 4.5.10 and 4.5.12 Damage Threshold 1000 W/cm2 CW, 0.5 J/cm2 with 10 nsec pulses, typical SuperMirrors may be subject to U.S. high technology export restrictions.
