Deflection prism
A deflection prism is an optical prism that deflects a light beam by refraction on at least one prism surface. They thus fulfill a function similar to that of deflecting prisms .
As a rule, a deflecting prism is understood to be a prism wedge in which the light falls obliquely on at least one prism surface and is deflected by the refraction of light. The deflection is usually less than 90 °. Other forms are a common, equilateral 60 ° prism, in which the light already falls obliquely onto the first surface, or the abatsche wedge , also known as a swivel wedge .
