A prism with a small vertex angle (generally less than 1/10 radian) is called an optical wedges, also known as a wedge mirror. When the light is perpendicular or nearly perpendicular to the wedge, the deflection angle θ=(n-1)A. where n is the refractive index of the wedge medium. The resulting deflection is therefore small and independent of the angle of incidence. In optical instruments, two optical wedges are often combined to make them rotate relative to each other to generate different deflection angles, or to convert the minimum deflection angle of light into the relative rotation angle of the two optical wedges to compensate for the small angle deviation of the measured light. It has applications in many optical instruments such as military rangefinders and camera viewfinders.
It has applications in many optical instruments astronomy, Biomedical/Medical, Communication, Industry, Military, Scientific Research, Others.
