Right Angle Prism |
|
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. 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. |
