Prisms
Prisms are blocks of optical material with flat, polished sides arranged at precisely controlled angles. Because small errors can inhibit proper operation, so angle specifications are critical. Prisms deflect or deviate light, invert or rotate an image, disperse light into component wavelengths, and separate polarization states. There are many kinds of prisms, many of which make use of the property of total internal reflection (TIR). Light incident upon an air/glass boundary at angles greater than the critical angle (approximately 42° for visible light and BK7 glass) is totally reflected.

Pentaprism
Prisms
Sunday-optics
Material: BK7, UV fused silica, sapphire, ZnSe, Caf2, Si, Ge, etc. Dimensions: 3mm-380mm Dimensional tolerance [Customer requirements]: +/-0.02mm or Customer requirements
Pentaprisms are widely used in laser levels, imaging, precision systems and optics. Their 90° deviation is independent of prism orientation, making them especially important where orientation cannot be precisely controlled. We manufacture high-precision pentaprisms with customer-specified coatings.

Littrow Prism
Prisms
Sunday-optics
Material: BK7, UV fused silica, sapphire, ZnSe, Caf2, Si, Ge, etc. Dimensions: 0.5mm-300mm Dimensional tolerance [Customer requirements]: +/-0.02mm or Customer requirements
A Littrow prism is usually a 30°/60°/90° prism with a reflective coating on its hypotenuse. A coated Littrow dispersion prism deflects the line of sight by 60°. An uncoated Littrow dispersion prism disperses light into its component spectrum.
