Nor-Cal Products’ thin film multi-channel monitors, crystal sensors, and feedthroughs support one of the more popular methods of thin film measurement and rate control - the crystal monitor, which utilizes the piezo-electric properties of a quartz crystal. A variety of feedthrough configurations with NW or CF flanges are available for single or dual crystal sensors, with or without water-cooling and pneumatic shutters. Our standard monitor measures film thickness and rate or frequency from two independent channels. Custom feedthroughs are available with a variety of flanges in all sizes.
