AT Quartz Crystals (20-100°C)
Gold or Alloy
The AT Standard is a stock replacement quartz crystal for most of the commercially available film thickness monitors. The AT Standard is available in 6 MHz, 14mm diameter (for Inficon™, Sycon™, Sigma™, and Maxtek™); 5 MHz, 14 mm diameter (for Balzers™), 5 MHz, 12.5 mm diameter crystals (for Ulvac™ and Sloan); and 8 mm diameter 5 or 6 MHz.

RC™ Quartz Crystals (20-250°C)
Gold or Alloy
Insensitive to frequency shifts caused by source radiation or film stress, the patented RC™ crystal disregards the rate spike that occurs when the deposition source shutter is opened. This crystal is ideal for OLED manufacturing, precision optical interference films, or next-generation electronic devices. Available in gold or alloy, in 6 MHz, in 14 mm (0.550″) and 12.5mm (0.490″) diameters. More

HT™ Quartz Crystals (250°C-400°C)
Gold or Alloy
It’s hard enough to find a quartz crystal that can operate stably above 100°C, let alone 300°C. The HT™ (high temperature) quartz crystal sensor can do just that. This crystal is ideal for processes requiring intense heat, such as ALD, CVD, OVPD, high temperature PVD, and thin film furnace processes such as selenization and indiffusion. More

SuperQuartz™ (400°C+)
Gold or Alloy
Standard quartz crystals are extremely noisy during processes that operate at temperatures above 100°C, hindering accurate and stable film thickness measurements. To solve this problem, Colnatec created the SuperQuartz(SQ)™ crystal that operates efficiently at temperatures of 500°C+. This crystal is ideal for high-heat processes such as ALD, CVD, OVPD, and high temperature PVD. More
