The index of BK7 is sufficiently high to guarantee the TIR of acollimated beam at 45 degrees internal incidence over the visible andnear infrared region. The possibility of significant TIR failure withconvergent or divergent beams should be kept in mind if polariza-tion is important. TIR can also fail if the hypotenuse face is notkept extremely clean. Even an almost invisible fingerprint can leadto TIR failure. An aluminum or silver coated hypotenuse is rec-ommended for applications where the right angle-prism is fre-quently handled, or where convergent or divergent beams are used.There is a slight loss of reflectance at all internal angles with the coat-ing, and no critical angle exists.

Prisms are blocks of optical material with flat polished sidesarranged at precisely controlled angles to each other. Prisms maybe used in an optical system to deflect or deviate a beam of light.They can invert or rotate an image, disperse light into its compo-nent wavelengths, and be used to separate states of polarization.

PRISM ORIENTATION

The orientation of a prism determines its effect on a beam of lightor image.

A viewer looks through a prism at an object and sees a virtualimage (see figure at top right). This image may be displaced fromthe original object, or it may coincide with the object if a dove prismis used. Furthermore, image orientation may differ from the object;in this case, the right angle prism shown has reversed left and right.

A real image (see figure at bottom right) can be formed only ifimaging optics are present in the system. Without imaging optics,the image is virtual. A virtual image has the same orientation as thereal image shown, but it can be viewed by the observer only bylooking back through the prism system.

ABERRATIONS FOR PRISMS

Prisms will introduce aberrations when used with convergentor divergent beams of light. Using prisms with collimated or nearlycollimated light will help minimize aberrations. Conjugate distancesthat include prisms should be long.

TOTAL INTERNAL REFLECTION

Rays internally incident upon an air/glass boundary at anglesgreater than the critical are reflected with 100% efficiency regard-less of their initial polarization state. The critical angle is given by:

and depends on the refractive index, which is a function of wave-

length. If, at some wavelength, the refractive index should fall to less

than √}}2≈ 1.414, the critical angle will exceed 45 degrees, and total

internal reflection (TIR) will fail for a collimated beam internally

incident at 45 degrees on the hypotenuse face of a right-angle prism.

Reflectance decreases rapidly at angles of incidence less than the

critical angle.

Dove prisms are used as image rotators. As the prism is rotated,the image passing through will rotate at twice the angular rate ofthe prism.

$ Dove prisms can be used with parallel or collimated light.

$ Normally used in TIR mode with the hypotenuse faceunaluminized.

$ The useful aperture can be doubled by aluminizing or silver-ing the hypotenuse face of two identical prisms with theirfaces cemented together.

$ Single layer, HEBBAR™, and V-coatings are available forentrance and exit faces. For HEBBAR coating, please specifythe /079 coating suffix since it is specifically designed for a45-degree angle of incidence.

Right-angle prisms can be used to direct a beam of light at90 degrees from the incident or to retroreflect a beam. A right-angle prism may also be used as a front surface mirror.

$ High transmission can be achieved, using the hypotenuse facein total internal reflection (TIR), with an antireflection coatingon the entrance and exit faces.

$ The prism can be used as an internal or external mirror byspecifying a metallic coating on the hypotenuse.

Most of the coatings described in Chapter 5, Optical Coatings,can be applied to prism surfaces. The commonly specified antire-flection coatings and high-reflection coatings are listed here foryour convenience. Please specify which surfaces require coatings.

The roof or Amici prism deviates or deflects the image throughan angle of 90 degrees. It is a right-angle prism whose hypotenusehas been replaced by a 90-degree TIR roof. Glass that does notcontribute to the clear aperture has been trimmed away to reducesize and weight.

$ Roof prisms are suitable for applications that demand bothright-angle deflection and image erection (a combination left-to-right angle deflection and top-to-bottom inversion,equivalent to a 180 degree rotation about the optical axis).

$ These are normally uncoated for use in TIR mode.

$ Protected aluminum or internal silver coatings may bespecified for roof surfaces when used in wide fieldapplications beyond TIR limits.

$ Antireflection coated entrance and exit faces are also available.

Penta prisms deviate beams by 90 degrees. The deviation isindependent of prism orientation. Melles Griot supplies prismswith two levels of deviation tolerance. Due to geometry, the reflectingsurfaces must be coated with a metallic or MAX-R coating. Penta-prisms come standard with an /011 protected aluminum coating.Alternative metal and MAX-R coatings are available and can beordered by appending the coating suffix to the product number.Coatings are specified in Chapter 5, Optical Coatings.

$ Image is neither inverted nor reversed as it is deviated by90 degrees.

$ 90-degree deviation angle applies to all rays transmitted bythe useful aperture, regardless of the angles between these raysand the optical axis (or entrance and exit face normals).

$ Antireflection coatings are available for entrance and exitfaces and can be ordered by appending the appropriatecoating suffix.

Equilateral dispersing prisms are used for wavelength separationapplications. A light ray is twice refracted passing through the prismwith total deviation denoted by vd in the figure below. Deviation isa function of refractive index, and hence wavelength. Angulardispersion ∆vd is the difference in deviation for light rays having dif-ferent wavelengths and varies with prism orientation.

$ Reflection losses are minimized for unpolarized rays travelingparallel to the base of the prism. This condition is calledminimum deviation.

$ Minimum deviation occurs when the ray and wavelengthangle of incidence at the entrance surface are equal to theangle of emergence (both angles measured with respect to thesurface normals).

$ Available in BK7 and F2 glass material. BK7 is more durableand has superior transmission, F2 offers superior dispersionbut is more fragile and sensitive to staining.

$ Antireflection coatings help reduce polarization at the prismsurfaces by increasing total transmittance.

where n is the refractive index.

Power (D) of a prism is measured in diopters and isdefined as the deflection of 1 cm at a distance of onemeter from the prism. Thus:

D= 100 tan(vd).

By combining two wedges of equal power in nearcontact, and by independently rotating them aboutan axis parallel to the normals of their adjacent faces,a ray can be steered in any direction within thenarrow cone. The deviation angle is specified withthe assumption that the input beam is normal to theperpendicular face. Deviation will change with inputangle. The equation to determine the deviationangle for the same input direction but otherwavelengths is:

vd = arcsin (nsinvw ) 4 vw

where vd is the deviation angle, vw is the wedgeangle, and n is the nominal index for BK7 at theappropriate wavelength.

Any ray entering the effective aperture of a retroreflector will bereflected and emerge from the entrance/exit face parallel to itself,but in the opposite direction of propagation. Solid retroreflectorsdepend upon the principle of total internal reflection and there-fore have acceptance angle limitations.

$ An incident beam, filling the effective aperture, is reflectedexactly back on itself.

$ Protective aluminum coatings can be applied to the rearreflecting surfaces to avoid TIR failure from acceptance anglelimitations. Simply append suffix /011 to the selected productnumber.

$ Antireflection coatings can be ordered by appending theappropriate suffix to product number. (See Chapter 5, OpticalCoatings.)

Hollow retroreflectors consist of three flat mirrors assembled intoa mutually orthogonal inside corner. Since the optical path for theseretroreflectors is air, they are usable throughout the entire opticalspectrum from the ultraviolet to the far-infrared.

$ These reflectors eliminate wavelength dispersion effects.

$ Aluminum with a protective overcoat is standard on theseretroreflectors to ensure high reflectivity over the visiblespectrum. A gold coating for improved IR performance and aUV-enhanced aluminum coating can also be provided on aspecial order basis.

$ These retroreflectors are available with an excellent wavefrontdistortion specification up to l/8, along with a tight beamdeviation specification of 0.5 arc seconds.

$ Hollow retroreflectors are used to construct delay lines forfemtosecond applications. Other applications includepollution detection and measurement applications, laserranging, conventional and FTIR spectroscopy, distancemeasurement, holography, and interferometric applications.

Post-Mounted Prism Holders Precision Prism Tables

Miniature Prism Table Retroreflector Holders

Allows post mounting of prisms up to 50 mm (2 inch)in size, and permit precise tilt adjustment in two axes.

This miniature prism table allows tilt adjustment and360° rotation for components of up to 15 mm in size.

For precision applications, this table mounted prismholder provides fine adjustment in all three tilt axes.

Post mounted holders are available for all standardretroreflectors. By retaining the retroreflector near theedge, they ensure that total internal reflection is notdisturbed.

PRISM HOLDERS

Prisms frequently have to be positioned and aligned to tight tolerances, however, their odd shapes often make this difficult to accomplish. Melles Griot offers a number of prism holders to facilitate this task in the laboratory.See Chapter 25, Mirrors/Beamsplitter Mounts and Prism Tables.
