VUV-UV CaF2 Right Angle Prisms



 

eSource Optics VUV Grade CaF2 Right-Angle Prisms are commonly used for image rotation and redirection of VUV-UV light.  VUV Grade CaF2 Right-Angle Prisms can be used to deviate a VUV-UV light path by 90° or 180°, depending on which surface is used as the input for the light source. Due to total internal reflection (TIR), our VUV Grade CaF2 Right-Angle Prisms can be used as a 90° bending prism or reflector. When the input VUV-UV light is incident on one of the prism's legs, it undergoes TIR at the glass/air boundary of the hypotenuse and exits via the other prism leg. This 90° deviation of the input light makes the right angle prism a suitable alternative for a UV mirror. 

Calcium Fluoride:  Calcium Fluoride (CaF2) exhibits good transmission properties from ~ 140nm Vacuum UV (VUV) to ~ 8.0um in the Infrared.  CaF2 is a relatively soft crystalline material and care should be taken as CaF2 is sensitive to mechanical and thermal shock.  CaF2 is a cubic single crystal optical material.
