6 results about "Compound prism" patented technology

A compound prism is a set of multiple triangular prism elements placed in contact, and often cemented together to form a solid assembly. The use of multiple elements gives several advantages to an optical designer: One can achieve spectral dispersion without causing the deviation of the beam at the design wavelength. Thus, light at the design wavelength which enters at an angle θ₀ with respect to the optical axis, exits the prism at the same angle with respect to the same axis.
