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.
