Absorption spectrometry

Recommendation 

The recommendation of Goyenchem-BL475 is suggested to 0.5~5% by GYC technical department.

The addition of film thickness is proportional to the blue light absorption rate. The addition can be adjusted by customer’s formula condition and film thickness.

Condition	Suggestion
Film thickness 250μm	0.5%-1%
Film thickness under 50μm	2%-5%
General plastic material and lens thickness 1.5-2mm	0.5%-0.8%
