N-BK7 Material Wedge Prism For Low-deviation Beam Bending In Optics

N-BK7 Material Wedge Prism For Low-deviation Beam Bending In Optics

Material:‌
1.N-BK7 Optical Glass‌: A high-quality borosilicate crown glass with exceptional homogeneity (refractive index: 1.5168 @ 587.6nm) and low bubble/inclusion content.
2.Precision Polishing‌: Surfaces polished to λ/10 flatness for minimal wavefront distortion.

Properties:‌
1.Low Angular Deviation‌: Designed for precise beam bending with deviation angles as low as ‌±1 arcminute‌, ensuring minimal beam displacement.
2.High Transmission‌: AR-coated options available (e.g., 350-700nm or 700-1100nm) to achieve ‌>99% transmission‌ per surface.
3.Thermal Stability‌: Low coefficient of thermal expansion (7.1×10⁻⁶/K) suits harsh environments (-30°C to 70°C).

Function:‌
1.Beam Steering‌: Bends light at a controlled angle (e.g., 1°–10°) without image inversion, ideal for laser alignment and optical path correction.
2.Dispersion Control‌: Minimizes chromatic aberration due to N-BK7’s uniform dispersion properties.

Applications:‌
1.Laser Systems‌: Used in fiber optic collimators, interferometers, and laser diode modules for beam shaping.
2.Industrial Metrology‌: Critical in autocollimators and alignment tools for precision manufacturing.
3.Defense & Aerospace‌: Integrated into targeting systems and LIDAR for stable beam redirection under vibration.
