CLAREX UV-Cut Acrylic
Blocks more UV than the standard clear sheets.
The standard CLAREX cast acrylic sheets include UV inhibitors which block UV below 375nm. The CLAREX UV-Cut filters are available for applications which require additional UV filtering. The factory has several options which block UV up to 480nm. Note that as the cut-in gets higher the sheets start to get a yellow tint. The N-039 is essentially a yellow filter.
Benefits
- Excellent optical characteristics
- No birefringence or double refraction
- Excellent weatherability
- Available smooth surface or non-glare surface
- Available with scratch & chemical resistant hard-coat
UV-Cut Filters are used in applications which are sensitive to UV light.
Applications
- Display protectors
- Optical filters
- Instrumentation
- Sensor windows
