The Planization Hard Coater PSR-300 of Chemalux CTC-300 Lab coats the backside surface using a spin coating technology.The rough surfaced surface is covered and smoothed with special index matching hard coatings based on Chemalux patent pending chemistries. This coating technology replaces fining and polishing steps, and keep the quality of digital machined surfaces. Chemalux Planization Hard Coater includes high pressure water washing, hard coating and curing processing steps.The process is fully automatic and self-contained. The coater contains two different coating solutions to be applied to low index (CR-39, Trivex, 1.56) and PC lenses.The coater is fully integrated and automatically cleans, coats and cures lenses in one quick, uninterrupted cycle, eliminating exposure to dust and dirt, minimizing lens handling, and bypassing lens inspection prior to the curing phase. With this process, labs gain increased throughput and consistently high yields.
