Process Spectrometer
Versa PS2000 |
 |
|
The process spectrometer Versa PS2000 (download datasheet) was developed for online transmission measurements of optical layers during production. It can be used for other tasks too, e.g. spectral transmission measurements of liquids or reflexion measurements during coating processes.
The firmware of Versa PS2000 allows to preprocess the measuring data. So it is possible to calculate process specific data such as reflectivity or layer thickness.
Versa PS2000 will also be available with an internal light source (halogen lamp or xenon flash lamp) or as a NIR version.
