Product Description

 Elevate Your Optical Systems with Unmatched Precision

The Double Side Super Smooth Flat Concave Mirror Substrate redefines performance in demanding applications like gravitational wave detection and ultrafast laser setups. Engineered with sub-nanometer surface smoothness (Ra <0.5nm) and λ/10 flatness tolerances, these substrates minimize wavefront distortion while supporting custom curvatures from 500mm to 8000mm radii. Whether you’re aligning cryogenic imaging arrays or refining EUV lithography tools, our dual-side polishing technology ensures consistent results across both surfaces—even for complex kickoff geometries.

Why Engineers Trust Our Mirror Substrates

  • Satellite optical communication payloads: Enable high-speed data transmission between orbiting satellites and ground stations with minimal signal loss, leveraging low-loss optical components. These systems maintain stability amid orbital vibrations and radiation, ensuring reliable connectivity for global communications and Earth observation networks.​
  • Hyperspectral imaging systems for surveillance drones: Capture detailed spectral data across 200+ bands, identifying materials and anomalies invisible to the naked eye. Lightweight, vibration-resistant optics ensure consistent image quality during long flights, aiding in border patrol, environmental monitoring, and disaster response missions.​
  • Laser rangefinders in armored vehicles: Deliver precise distance measurements (±0.5m at 10km) even in dusty or foggy conditions, critical for target acquisition and navigation. Ruggedized optics withstand vehicle vibrations and shock, maintaining accuracy in combat environments where split-second decisions matter.​
  • High-energy laser weapon beam steering: Precisely direct laser beams with sub-milliradian accuracy, even under high thermal loads, to engage fast-moving targets. Advanced materials resist heat-induced distortion, ensuring the beam stays focused on target for effective, energy-efficient operation in defense systems.​
  • Space telescope primary mirrors: Maintain <λ/20 surface accuracy across extreme temperature swings (-150°C to +50°C) to capture sharp cosmic imagery. Large, lightweight designs (up to 8m diameter) minimize launch mass while maximizing light-gathering power, enabling breakthroughs in astrophysics and planetary science.
