45˚ Reflection Prisms are used to deviate the line of sight by 45˚. The reflecting surfaces are aluminized with black paint for protection.
• Beam Deviation: 45˚±5'
• Dimension Tolerance: ±0.1
• Flatness: λ/4 at reflection surface
λ/2 at transmission surface
• Surface Quality: 60-40 scratch-dig
• Clear Aperture: 90%
• Coatings: Reflecting surfaces are aluminized with black paint.
Entrance and Exit surfaces are 1/4 wave MgF2
coating at 550nm for 0˚ angle of incidence.
