CLAREX® Anti Reflection Filters (AR Acrylic)
Additional coatings prevent surface scratching and smudging
COATED vs. UNCOATED: An uncoated piece of acrylic on one side and an antireflection coated piece on the other side.
Reflection of a very bright light source. The sample on the right (with blue reflection) has AR coating. Reflection intensity is much lower.
CLAREX® AR COAT FILTER - is treated with a multi-layer AR coating which prevents light reflection. Additional coatings prevent surface scratching and smudging. May be combined with non-glare surfaces to further reduce reflection.
APPLICATIONS - Anti-reflection panel for LCD, CRT, LET, EL, PDP, VFD, FED, bar code scanners, etc.
THICKNESS - 0.2 to 5.0mm
SIZES - 290mm x 360mm standard | Custom sizes available upon request.
TYPES - Anti-reflection available one side or
two sides with or without anti-smudge coating.
Custom-tuned anti-reflection coatings are
available for NIR or UV applications –
contact us.
MACHINING / PRINTING - Available to customer specification.
- Excellent optical characteristics & reflection prevention
- Excellent transmission, greater than 98% visible range
- Excellent surface hardness & impact resistance
- Excellent smudge resistance. Anti-smudge coating makes the surface easier to clean (but cannot 'prevent' fingerprints).
COLORS - Available in clear and many colors. See standard colors.
Custom-Tuned AR Coatings Available!
