Continuous Optical Thin Film Coater
COFC-1300
COFC-1300 is a continuous optical thin films coater consisting of three chambers. Transferring work pieces without breaking vacuum, this can mass-produce continuously the optical filters.
■
Non-vibrating carrier (dome) transfer system
■
Central rotation system to improve rotational precision and to restrain particle generation
■
Max rotational speed at 20rpm to improve thickness controllability
■
12 points type high precision optical thickness monitor
■
Quartz crystal microbalance monitor (max 80 monitors)
■
Sophisticated film quality by RF ion source
■
Automatic dome mounting system (Automatic carrier transfer system as option). Extra vacuum chamber as option
