Product Description

D25 Super High Reflective Spherical Mirror

Whether you're calibrating space telescopes or optimizing laser resonators, the D25 Super High Reflective Spherical Mirror delivers 99.999% reflectivity across UV to IR spectra. Designed for researchers and engineers who refuse to compromise, this mirror combines nano-level surface accuracy (<λ/20 RMS) with customizable geometries to fit exact experimental needs.

Key Innovations

  • Zero-scatter surfaces: Ra 0.12nm roughness minimizes photon loss in quantum experiments, ensuring precise control of quantum states by reducing light deviation. This ultra-smooth finish preserves photon coherence, critical for quantum computing and entanglement studies where even tiny scatter can disrupt delicate quantum interactions.​
  • Thermal-proof design: Operates flawlessly from -50°C to 150°C (expandable to 4K cryogenic setups), maintaining dimensional stability in extreme temperature swings. Ideal for quantum cryostats, space sensors, and industrial ovens, it prevents thermal-induced distortion that could compromise data accuracy in high-precision systems.​
  • Radiation resilience: 10-year reflectance warranty even under 500kGy gamma exposure ensures long-term reliability in nuclear facilities, space missions, and radiation therapy equipment. The robust coatings resist degradation, maintaining optical performance in harsh environments where radiation would otherwise damage standard components.

Trusted by Pioneers

Used in:

  • Gravitational wave interferometry at LIGO-affiliated labs: Depend on ultra-precise optics with zero-scatter surfaces (Ra 0.12nm) to detect faint spacetime ripples, as even minimal photon loss would obscure signals from black hole mergers. Thermal-proof designs maintain stability, ensuring interferometer arms stay aligned to measure subatomic-scale length changes.​
  • EUV lithography alignment systems: Require thermal-proof optics operating flawlessly across extreme temperatures, with zero-scatter surfaces to ensure precise beam alignment for 3nm chip manufacturing. These components minimize light deviation, critical for patterning tiny circuits where misalignment would ruin wafer yields.​
  • Mars rover spectrometers: Need radiation-resilient optics with 10-year reflectance warranties to withstand Martian radiation and dust, while thermal-proof designs function through frigid nights and warm days. Zero-scatter surfaces preserve signal integrity, enabling accurate analysis of rock compositions for signs of past life.
