Super Low Loss Flat Mirror: Precision Optics for Extreme Environments

When every photon counts, our Super Low Loss Flat Mirror delivers unmatched performance in mission-critical applications. Designed for aerospace, defense, and high-power laser systems, these mirrors combine <0.1% absorption rates with >99.999% reflectivity to minimize signal loss under thermal stress, radiation, and mechanical shock.

Why Choose Our Ultra-Low Loss Mirrors?

Military-Grade Durability

Thermal Stability: Operate seamlessly from -270°C to +300°C, enduring cryogenic chambers and industrial heat without structural shifts, critical for quantum research and aerospace sensors where temperature extremes would warp standard optics, preserving alignment in deep-space probes or ultra-cold labs.
Radiation Resistance: Proven performance in LEO/MEO satellite orbits, withstanding proton/electron flux that degrades conventional mirrors, ensuring consistent reflectivity for communication links and Earth-observation systems, vital for missions requiring long-term reliability in harsh space environments.
Surface Precision: λ/10 flatness & <0.5 nm roughness for zero wavefront distortion, eliminating light scattering in high-resolution imaging and laser interferometry, ideal for semiconductor metrology and astronomy telescopes where even minor irregularities would compromise data accuracy or image clarity.

Custom-Built Performance

Material Options: ULE, fused silica, or sapphire substrates—ULE for extreme thermal stability, fused silica for high-power laser resilience, sapphire for 9 Mohs hardness, enabling tailored solutions for quantum labs, industrial lasers, or aerospace sensors based on specific environmental demands.
Coating Flexibility: 420nm-3000nm wavelength optimization, from visible to near-infrared, enhancing performance in hyperspectral imaging and laser communication, ensuring maximum reflectivity at target wavelengths to minimize signal loss in satellite links or precision spectroscopy setups.
Compact Sizes: From φ3mm to φ100mm with anti-reflective backing, fitting into miniaturized sensors and large optical arrays alike, ideal for drone-mounted LIDAR and ground-based telescopes, balancing space efficiency with optical performance in diverse applications.
