Now >> JS01 Evaporation Material/Coating Material

JS01 Crystal Evaporation Material is the high refractive index Mixture researched and developed by our company independently. It is applied for the coating of antireflection films and multilayer. The product has the following characteristics:

■ Uniform components, large density and high purity;

■ Visible to near-infrared waveband without absorption, 360nm - 7000nm high transmittance;

■ Melt completely before deposition;

■ No deflation and splash in the melting process;

■ Uniform film with consistent thickness.

3. AR film reliability test

Project	Conditions	Results
Environmental test	Lasting: 48H	Through test, there is no mist and devitrification. The spectral curve has no apparently change. Both appearance and function are ok.
	Temperature: 80℃∽-20℃
	Humidity: 75%
	Circle index: 4
Film toughness test (after the environmental test)	Moisten stencil paper with acetone. Wipe back and forth at the same place for 25 times with 1-2kg strength	The film doses not peel off. Regard as ok.
	Make the high-strength rubber belt closely cling to the lens surface. Quickly tear out the belt in 90 degree. Repeat it at the same place for 3 times.

4. Conclusion:

In the vapor deposition of JS01 Crystal Evaporation Material, there is no spattering. And Material outgassing is minimal. The refractive index is stable. It has good repetitiveness. This material is suitable for stable batch production of the AR film.
