The stability of laser optical systems often lies in the precision details of their core optics.
Designed specifically for 45° beam splitting, beam conditioning, and infrared imaging applications, we present the 45° Elliptical Zinc Selenide (ZnSe) Polished Optics. Manufactured from high-purity substrates and ultra-precision polishing processes, it overcomes the common limitations of conventional round optics—such as beam occlusion, poor system compatibility, and excessive optical loss—delivering high-performance optical solutions for mid-infrared laser systems, R&D testing, and industrial equipment.
Robust Material, Maximum Optical Performance
Fabricated from high-quality CVD-grown zinc selenide with exceptional purity and minimal trace impurities, these optics fundamentally reduce scattering losses. They feature extremely low absorption at CO₂ laser wavelengths, combined with high thermal resistance and mechanical strength, ensuring stable operation in high-power laser environments.
45° Elliptical Customization – Enhanced System Compatibility
Unlike conventional circular optics, the dedicated 45° elliptical geometry precisely matches diagonal optical path designs, effectively eliminating structural interference and maximizing the clear aperture. The standard 45° inclination angle is tightly controlled, ensuring stable splitting ratios, distortion-free beam delivery, and suppression of stray light—ideal for compact, high-precision optical system integration.
Ultra-Precision Polishing – Low Loss, High Stability
Advanced polishing techniques yield exceptionally smooth surfaces, completely eliminating scattering and loss caused by scratches or surface defects. The optics exhibit uniform stress distribution, tight dimensional tolerances, and superior surface figure accuracy, ensuring minimal deformation and excellent aging resistance even under prolonged high-power operation. This guarantees long-term, reliable system performance and significantly reduces maintenance costs.
