Optical Prisms Specifications

Help with Optical Prisms specifications:

Prism Type

			The shape of a prism determines its effect on a beam of light or image.
	Your choices are...
	Anamorphic		Anamorphic prism pairs are used mainly to correct the asymmetric beam shape of a laser diode from elliptical to near circular shape.
	Corner Cube Retroreflector		Corner Cube Retroreflector prisms are designed to reflect any ray or beam entering the prism face, regardless of the orientation of the prism, back onto itself.
	Dove		Dove prisms are a truncated form of right angle prism which use total internal reflection to produce an image that emerges without deviation but is inverted. The main application for these prisms is as image rotators.
	Equilateral		Equilateral prisms are used routinely as dispersing elements where spectral separation is required. They provide better brightness than diffraction gratings.
	Penta		Penta Prisms deviate an incident beam through 90 degrees without inverting or reversing it. They also show constant deviation of 90 degrees, regardless of prism orientation. Five sides when viewed in cross section.
	Rhomboid		Rhomboid prisms are used primarily for controlling and redirecting the optical path without affecting the image orientation.
	Right Angle		Right Angle Prisms can be used to direct a beam of light at 90 degrees from the incident, or to retroreflect a beam.
	Roof		Roof Prisms, also known as Amici Roof Prisms or Right Angle Roof Prisms, invert and reverse an image as it is deflected 90 degrees.
	Wedge		Wedge prisms are mainly used with laser beams, either for elimination of reflections from the second surface, or for beam steering.
	Other		Any other prism type not listed.

Largest Dimension

	Largest Dimension		Prisms come in a wide variety of shapes with sides of different lengths. This is the largest dimension of that prism.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Material Specifications

	Prism Material:		Prism Material influences the performance of a prism.
	Your choices are...
	BK7 Glass		BK7 Glass is boro-crown glass (borosilicate glass). BK7 has a wavelength range of 330-2100 nm and an angular dispersion of 0°42'37".
	F2 Glass		F2 has a wavelength range of 350-2200 nm and an angular dispersion of 1°40'45".
	SF10 Glass		SF10 has a wavelength range of 400-2400 nm and an angular dispersion of 2°58'25".
	UV-grade Fused Silica		UV grade fused silica offer improved transmission in the ultraviolet region compared to crown glass. It's wavelength range is 200-2500 nm and has an angular dispersion of 0°34'01".
	Other Material		Any other prism material not listed.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Prism Coatings

	Reflective Coating?		Reflective Coating helps reduce loss of light due to transmission.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Antireflection Coating?		Antireflection Coating helps reduce loss of light due to reflection.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
