1 Cotings Wedge Steer bems in opticl systems Cn be used in pirs for continuous ngulr djustment T Hving selected n pproprite wedge, it is esy to crete precise bem devition without ffecting other bem prmeters. If two wedges re used together with the sloping surfces in close proximity, it is possible to produce continuous vrition of bem devition by counter rotting the wedges. Wedge prisms re mde from lterntive mterils, such s UV grde fused silic, nd different shpes nd sizes or with vrious nti-reflection cotings.

Right ngle prisms re often preferble to n inclined mirror in pplictions involving severe coustic or inertil lods, becuse they re esier to mount nd deform much less thn mirror in response to externl mechnicl stress. As long s cceptnce ngle limittions for TIR from the roof fces re not exceeded, right ngle prisms cn serve s retro reflector, turning bems bck to the originl direction.

4 Opticl Components Corner Cubes Cotings Mirrors Lenses Polrizing Optics UV & IR Optics Incident light devites by 180 degrees independently of the ngle of incidence These prisms hve 3 mirror surfces mking ngles of 90 to ech other, juxtposed to form the corner of cube with the entrnce fce perpendiculr to the cube digonl. Respective of n incident direction, ll bems re reflected bck to the originl direction. Solid corner cubes re used in high precision pplictions or with lsers over very long distnces. These ngle insensitive mirrors therefore find frequent pplictions in situtions where orienttion is difficult or impossible to control nd where mirror would therefore be unstisfctory.
