The Spectrum-Pro combines the strengths of a precision optical photometer and quartz crystal monitor to provide a new level of precision in end-point detection of optical coatings. It enables a wide range of monitoring strategies including reflectance, transmittance, and direct monitoring. Its newly designed optical components maximize light throughput, minimizes noise, and simplifies alignment. Optics can be customized for virtually any wavelength or chamber configuration. The system uses commercially available components for ease of maintenance and is compatible with a wide variety of crystal monitoring devices.
