NIDEK - AR (Anti Reflection) Coating

AR (Anti-Reflection) Coating by Vacuum Evaporation Method

Minimizing the reflectance of plastics used for front panel of LCD etc.
Higher transmittance

Optical Properities (Single Side)

Low reflectance in wider range of wavelength
Extremely minimizing the reflection color

Optical Properities (Single Side)

Illuminant D65 - CIE Chromaticity Diagram

Applicable to non-hard coated materials which enable to obtain adequate adhesiveness without hard coating such as aspherical acrylic lens and cyclo-olefin polymer, copolymer.

Samples : Aspherical Lenses

Usable under the severe environment required for automotives, etc.

Superior resistivity on UV

Physical Properties*

Salt Water Spray Test (Salt Water Resistivity Test)
	Conditions
		Per JIS Z2371, 28 days
		Inspected substrate: MR-200 by MITSUBISHI RAYON.CO.LTD.
	Results
		Contact angle : 108 degrees
		Adhesion (Tape test) : Passed

The test was conducted by the Nagoya Municipal Industrial Research Institute, using a salt water spray testing machine made by Suga Test Instruments Co, Ltd.
Test conditions: chamber temperature 35 ± 1 °C, approx. 100% humidity, 5% salt water density (50g / 1000ml), PH6.5-7.2

*All of optical and physical properties are not the guaranteed values but the results of the measurement.

**All the NIDEK's coating for optical application are individually designed on a make-to-order basis.
