Calcium Fluoride Crystals
Product Information
|
LITHOTEC® calcium fluoride crystals grown from purest (synthetic) raw material are required for illumination and projection optics in 248 nm, 193 nm and 193 nm immersion micro / lithography technologies and laser applications.
Benefits
LITHOTEC® calcium fluoride crystals complete the application range of optical materials from VUV to IR with very good transmission ranging from 130 nm to 9 µm due to its
- High projection optic quality
- High production volume
- High purity
- High laser durability
- High refractive index homogeneity
- Excellent UV transmittance
- Low stress birefringence
|
Key Applications
|
The very high laser damage threshold of LITHOTEC® calcium fluoride crystals makes it the first choice material for:
- Excimer laser optics
- Beam delivery
- Illumination systems operating at 45nm node
- Optical systems in lithography, astronomy, photography, HDTV zoom lenses, microscopy
- Sensors (especially IR-spectrum)
- Spectrometers
- Medical lasers
|
Forms of Supply
|
SCHOTT North America offers calcium fluoride components and blanks with different crystal orientations (<111>, <100>, random or others on request) along with different surface qualities (raw, cut, ground or polished), depending on the individual requirements.
