Anti-reflective Coated Optical Penta Prism For Maximizing Transmission Efficiency
Anti-reflective Coated Optical Penta Prism For Maximizing Transmission Efficiency
1. Material & Construction
Substrate: Precision-grade BK7 glass or UV-fused silica (transmission range 350-2500nm).
Coating: Multi-layer MgF₂ or proprietary broadband AR coating (Ravg <0.5% @ 400-1100nm).
Tolerance: 90°±1 arcmin deviation, λ/8 surface flatness (MIL-PRF-13830B compliant).
2. Key Properties
Transmission Efficiency: >99.5% light throughput with <0.3% reflectivity per surface.
Beam Stability: <0.1 mrad angular deviation for precise beam alignment.
LIDT: >10 J/cm² (1064nm, 10ns pulse) for high-power laser applications.
Environmental Resistance: Operates from -40°C to +85°C with humidity protection.
3. Core Functions
Beam Steering: Maintains 90° deflection regardless of prism orientation.
Image Erection: Corrects image inversion in optical systems.
Spectral Optimization: Minimizes energy loss across UV-VIS-NIR spectra.
4. Applications
Laser Systems: Fiber laser cutting/engraving machines (IPG/YAG compatible).
Metrology: Interferometers and autocollimators for industrial measurements.
Defense Tech: Target designation systems and rangefinders (MIL-STD-810H certified).
Aerial Imaging: Drone-mounted LIDAR and hyperspectral cameras.
