RU60

Broadband spectrometer

The JETI broadband OEM spectrometer RU60 is a flat field spectrograph combined with a powerful processing electronics. It can be used for precise spectroscopic measurements, where a good linearity and a high optical resolution is needed. It includes an imaging grating and a correction mirror. RU60 is available with and without mechanical shutter.

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

Accessories

Fiber optic cable
Fiber Optic Cable (core diameter 200 µm, both sides terminated by SMA connectors) is available for all JETI spectrometers. The normal flexible cable has a length of 1 m (sma 200/1). Additionally, a nonflexible version with a length of 10 cm (sma-sma 200) is offered.

Fiber coupled diffusor (ACC 028)
The optical fibers can be combined with a fiber coupled diffusor to convert the spectrometers into Irradiance meters. A suited calibration is optionally available.
