VIS Spectrometer with Internal Light Source

specbos 2001

specbos 2001 (download datasheet (137kB)) is a fiber coupled VIS spectrometer with an internal light source. It is characterized by an excellent straylight performance, a high sensitivity and small dimensions. specbos 2001 can easily be connected with an USB port of the PC and the measurement can be started immediately - a real plug and play solution. The device is bus powered.

Reflexion of gray plastics

specbos 2001 is one of the most compact spectro photometers available on the market.

The device can be delivered with various fiberoptic measuring heads, e.g. transflexion dip probes.
