30° - 60° - 90° Littrow Prisms
Ray Deviation of 60° If Coated
Ideal as a Dispersion Prism if Uncoated
Right Handed Image
Littrow Prisms have two main applications.
1. Uncoated littrow dipersion prisms are used to disperse light into its component spectrum.
2. Coated littrow dipersion prisms are used to deviate the line of sight by 60°. Reflection coating at the long Right angle surfaces could be used one glasses for climbing and reading laid at the bed.
