UV Optics

UV Excimer Laser Optics

Optics for 193nm – 400nm applications

When working at such short wavelengths, great care must be taken to prevent the occurrence of small defects in the optical components or their coatings. Also, coating layers are very thin requiring a high degree of precision and control in their deposition.

Many common optical glasses cease to transmit at these wavelengths so it is essential to use a material such as UV grade Fused Silica, Calcium Fluoride or Magnesium Fluoride as component materials for transmissive optics.  The fluoride materials are soft and hygroscopic which necessitates special handling and knowledge of the material shaping and polishing characteristics.

Why Lambda? 

Lambda has a great deal of experience in design, manufacture, and coating of UV optics.  When working at such short wavelengths, great care must be taken to prevent the occurrence of small defects in the optical components or their coatings.  many common optical glasses cease to transmit at ultra-violet spectrum so materials require a higher level of precision during fabrication.  Also, the coating layers are very thin, requiring a high precision and control during the thing film deposition process.
