pecifications

• Material: N-BK7, Grade A Fine Anneal
• Surface Flatness: λ/10 (Over the Clear Aperture)
• Surface Quality: 40-20 Scratch-Dig
• Clear Aperture: 70% of Entrance Face Dimensions
• Reflective Coating: Aluminized
• Dimensional Tolerance: ±0.1 mm
• Beam Deviation: 90° ± 1 arcmin

Penta Prisms are fabricated from N-BK7 glass, come with a reflective coating to ensure proper performance, and are available with four different clear apertures. A Penta Prism deviates an input beam or image through 90° without inverting or reversing the image. In addition, the 90° beam deviation is not dependent on a precise alignment of the prism with respect to the incoming beam or image.
