High-accuracy Optical Glass Roof Prism For Minimal Distortion In Viewing System

Material:‌

1.Optical glass substrate‌ (e.g., BK7 or fused silica) with high refractive index homogeneity (Δn ≤ ±2×10⁻⁶) for minimal wavefront distortion.
2.Precision-polished surfaces‌ (λ/10 flatness) and ‌dielectric coatings‌ (broadband AR coatings at 400-700nm) to reduce reflections (<0.5% per surface).

Properties:‌

1.Minimal distortion‌: Roof angle accuracy of 90°±3 arcseconds ensures image fidelity without tilt or deviation errors.
2.High durability‌: Resists thermal shock (-30°C to 70°C) and mechanical stress, ideal for rugged applications.
3.Low chromatic aberration‌: Optimized glass selection mitigates wavelength-dependent dispersion.

Function:‌

1.Beam deviation‌: Redirects light at 180° while maintaining image orientation, critical for erecting systems.
2.Distortion correction‌: Compensates for aberrations in binoculars, rangefinders, and surveying instruments.

Applications:‌

1.Defense/Aerospace‌: Used in periscopes, HUDs, and targeting systems for accurate imaging under vibration.
2.Medical devices‌: Integrated into endoscopes and surgical scopes for clear, undistorted visuals.
3.Industrial metrology‌: Ensures precision in alignment tools and laser interferometers.
