Optical bk7 glass wedge prism

Product Description

There are many types of optical prisms,such as wedge prisms,righe angle prism,rhombohedral prism,dispersing prism etc.each having a particular geometry to achieve the reflections necessary to perform a specific imaging task.Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering. Standard and broadband antireflection coatings are available upon request.
