BK7 Right-Angle prisms

Features: Achieve a 90° Light Path Bend

Applications: Used in Combination for Image/Beam Displacement,Image and Beam displacement system

Right-Angle prisms are commonly used to achieve a 90 degree or 180 degree light path bend. Depending on prisms orientation, images will be inverted,but correct left-to-right. Utilizing the character of critical angle, highly-efficient reflectiion inside is one of basic function of right angle prisms. Right angle prisms are easy to be mounted, have better stability and hardness for mechanical stress, are the best choice for all kinds of appartus and instruments.
