Diameter 25.4mm Deviation Angle 6degree BK7 Wedges Prism

Wedge prisms with the plane surfaces at slight angles(which divert the paths of light through angles by refraction instead of reflection) are called optical wdeges.

Optical wedges are used in fire control and optica alignment instruments,they may be used where the angle of deviation required is a matter of fractions of seconds.the angle at which a wdege diverts a path of light depends on the angle between the entrance and emergence faces and the index of refraction of the glass

N-BK7 Wedge Prisms are best for laser beam steering applications and are offered in 2°to 10°.Moreover, they can be quoted uncoated as well as coated with any of three standard AR coatings below
