• Ray Deviation of 60° if Coated
• Ideal as a Dispersion Prism if Uncoated
• Right Handed Image
TECHSPEC® 30°-60°-90° Littrow Dispersion Prisms
can be used for a variety of applications. Uncoated
littrow dipersion prisms are used to disperse light into
its component spectrum. Coated littrow dipersion
prisms are used to deviate the line of sight by 60°.

• Selectively Diffract Light Based on Polarization
• >96% Efficiency and <4% Leakage into Zero Order
• 0,45 mm Thick Transmission Grating
Polarization Gratings are used to selectively diffract light based on polarization state with the angle of diffraction
dependent on the grating film design. Unpolarized light is diffracted evenly between the positive and
negative first orders while circularly polarized light is diffracted entirely to one order with the polarization
state being maintained. These gratings are designed for high transmission and greater than 96% diffraction efficiency,
resulting in a maximum of 4% of light leaking into the zero order. Polarization Gratings can be used to
provide non-mechanical beam steering and are capable of offering wide-area coverage in imaging and sensing
applications with minimal space requirements and negligible added system weight. Applications for polarization
gratings include augmented reality (AR) systems such as AR headsets, telecommunication devices, and

• Ideal for Light Dispersion
• Sizes Ranging from 5 - 50 mm
• Available Uncoated or Anti-Reflection Coated
Equilateral prisms feature three equal 60° angles and
are often referred to as dispersing prisms. Equilateral
prisms are ideal for wavelength separating applications.
Our TECHSPEC® Equilateral Prisms are
available uncoated or with a single layer MgF2 antireflection
coating.
