DE50

Broadband OEM spectrometer

The new JETI broadband OEM spectrometer DE50 is a flat field spectrograph combined with powerful processing electronics. It is available in two versions: DE50 basic and DE50 expert.

JETI DE50 is designed for a wide range of applications. Its broad spectral range makes it suitable for applications in industrial process monitoring, integration into automated measurement systems and optical quality control.

The spectrometer can be operated with the intuitive measuring software JETI VersaSpec.

Fiber optic cables
Fiber Optic Cables (both sides terminated by SMA connectors) are available for all JETI spectrometers. The normal flexible cable has a length of 1 m. Additionally, a nonflexible version with a length of 10 cm is offered.


Fiber coupled diffusor
The optical fibers can be combined with a fiber coupled diffusor to convert the spectrometers into Irradiance meters. A suited calibration is optionally available.
