Technical Advantages
Ultra-High Purity Material：Monocrystalline silicon prisms with >99.99999% purity ensure minimal optical scattering and maximum infrared transmission efficiency.
Precision Manufacturing Expertise：Sub-micron surface flatness (λ/10 @ 633nm) achieved through diamond-turning technology, guaranteeing exceptional beam steering accuracy.
Broad Infrared Compatibility：Optimized for 1.2–15μm wavelength range, ideal for thermal imaging, FTIR spectroscopy, and CO₂ laser systems.
Thermal & Chemical Resilience：Operate reliably in extreme conditions (-200°C to +400°C) with resistance to humidity, acids, and organic solvents.
Custom Design Flexibility：Tailored prism geometries (right-angle, dove, penta) and anti-reflective coatings (DLC, Au, AR) for application-specific performance.
Low Absorption Loss：Near-zero optical absorption (<0.02 cm⁻¹ at 10.6μm) enhances energy efficiency in high-power laser applications.
