Used to Achieve a 90° Light Path Bend
• Used in Combination for Image/Beam Displacement
Right angle prisms are generally used to achieve a 90° light path bend. Depending on prism orientation, images will be inverted, but correct left-to-right (see illustration at left). If a right angle prism is rotated 90°, images viewed through the prism will be erect, but reversed left-to-right. Prisms can also be used in combination for image/beam displacement
