GCL-03013 Equilateral prisms 

 

An equilateral dispersing prism has an equilateral triangle in the crosssection with the three sides of equal length. They are used for wavelength separation. A light ray is refracted twice, passing through the prism with total deviation denoted by qd top angle. Deviation is a function of refractive index, and hence wavelength. Angular dispersion is the difference in deviation for light rays having different wavelengths and varies with prism orientation.

 

• Angles:                            60˚±2'
• Material:                          SF11
• Flatness:                          λ/4
• Surface Quality:               60-40 scratch-dig
• Clear Aperture:               90% surface area
• Coatings:                        1/4 wave MgF2 coating at 550nm for all 3 surfaces
