VUV-UV Optical Wedged Windows

 

Vacuum Ultraviolet to UV (VUV-UV) Optical Wedged Windows are available from select VUV Grade Magnesium Fluoride (MgF2); Calcium Fluoride (CaF2), Sapphire & UV Grade Fused Silica with a Wedge angle of 30 arc minutes in both 0.5" & 1.0" Diameter sizes.  The 30 minute wedge angle minimizes interference effects between surfaces.  The Reflected VUV-UV beams from both surfaces are separately usable in VUV-UV Laser applications. 

 

 

Magnesium Fluoride:  VUV Grade Magnesium Fluoride (MgF2) exhibits high transmission properties from ~ 110nm Vacuum UV (VUV) to ~ 6.0um in the Infrared.  MgF2 is a relatively hard crystalline material resistant to mechanical and thermal shock.  MgF2 is a birefringent crystal typically oriented along the optical axis to avoid birefringent effects in optical windows & lenses.  MgF2 Axis Orientation is within +/- 5 degrees. 

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.

Sapphire:  Sapphire (Al2O3) exhibits good transmission range extending from the ~ 150nm Vacuum UV (VUV) to ~ 5.0um in the Infrared.  Sapphire is an exceptional hard material and can only be scratched by a few materials other than itself.  Sapphire is chemically inert and insoluble to water, common acids, or alkalis at temperatures up to ~1,000 °C. Sapphire is typically oriented so that the c-axis of the crystal is parallel with the optical axis.

UV Grade Fused Silica (UVFS):  Synthetic form of silicon dioxide made from SiCl4  ,which transmits light over a very broad range of wavelengths from ~ 170 nm to 2.5 µm.  UV Grade Fused Silica is a high-purity material which has excellent thermal stability, high transmittance and is used as a UV to NIR material for many optical components.

VUV-UV Optical Wedged Windows are 30 minute wedge angle polished round VUV-UV optical windows typically used in general VUV-UV applications such as Deuterium (D2) Lamp and VUV-UV Laser Sources to isolate environments while allowing short wavelength VUV-UV light to transmit as short as 120nm.   VUV-UV Wedged Windows are generally used to eliminate fringe patterns and to help avoid cavity feedback. VUV-UV Wedged Windows are useful for protecting a laser output from environmental effects and for beam sampling applications. and or protecting other components within an VUV-UV optical assembly, VUV-UV instrument or VUV-UV laser.
