Precision UVFS，BK7 Right Angle Prisms
WISOPTIC advantages of right angle prisms
• High angle precision (<5 second)
• High flatness(<lambda/10)
• High angle pyramid tolerance(<5 second)
• Sorts of material: BK7 Grade A optical glass, Corning Fused Silica 7980, JGS1 UV Grade Fused Silica, and JGS2 UV Grade Fused Silica
• Competitive price and lead time
Right angle prisms are generally used to bend image paths or redirect light at 90°. This produces a left handed image and depending on the orientation of the prism, the image may be inverted or reverted. Right angle prisms can also be used in combination for image/beam displacement.
The advantages of right angle prisms
The capability of right angle prism to alter the image makes it a
staple component in optical systems ranging from high-performance
applications in scientific, healthcare and industrial fields, as well as
general use optical instruments such as telescopes or binoculars.
Right angle prisms offer a significant advantage compared to typical
mirrors because of greater resistance to mechanical load and external
stress. This makes them more suitable for applications which operate in
demanding conditions, such as vibrations or rapid movements. Prisms
provide also enormous improvement in terms of ease of mounting and
alignment, which reduces application complexity, cost and time to
market.
