Features
- A right-angle prism can be ***d as a mirror substitute.
- Prisms can stand on their own without special holders and can be installed in a variety of ways, making them ***ful for miniaturizing devices.
- In addition, the angular accuracy and surface accuracy of the prism are very high, and it is possible to *** the prism directly bonded to the machined parts.
- RPB1~3 ***s slope reflections as a substitute for mirrors.
- RPB1 ***s the critical angle of the prism for the reflection of the slope and is coated with an anti-reflection film on the two surfaces where light enters and exits the prism, RPB2 is coated with a reflection film (Al+MgF2) on the slope so that it can be ***d even at an incident angle below the critical angle, and RPB3 does not allow light to enter the prism and is reflected on the slope surface.
- RPB4 is ***d for two-sided reflections sandwiching the top angle (right angle).
- It can be ***d as a right-angle reference source or when observing two opposing directions simultaneously.
- RPB5 is ***d to return light at the same angle to the horizontal direction as the incident light.
- It is ***d in double-pass interferometers and autocorrelators.
- We also have non-coated prisms.
- * Measured A dimension is slightly shorter since it includes chamfer.
- * The tolerance is defined by the sides of the triangle formed by the slope and the two bases.
- * When light enters the slope from the air, most of the light escapes to the prism side and only a part of the light is reflected.
- * If light is applied at an incident angle of 41 degrees or less (critical angle or less) from the glass side to the no-coat surface, some light will be transmitted to the air side and total reflection will not occur.
- * Fingerprints and dirt on the no-coat surface may prevent total reflection even above the critical angle.
- * Do not let the no-coat surface come in contact with anything.
- * RPB5 should be ***d in the range of 0±5.7 degrees against the slope.
- If this setting is exceeded, the camera will not be fully reflected.
- * RPB2 reflects even at angles smaller than the critical angle due to the Al coat, but its reflectivity is 12% lower than that of RPB1.
