Jeti Specbos 2501 UV VIS NIR spectroradiometer
JETI specbos 2501 is the evolution of the successful models specbos 1211-2 and the spectraval series. It is a fast and precise broadband spectroradiomter, which is available in three basic models: specbos 2501, specbos 2501-NIR and specbos 2501-UV. These basic models can be customized by combining with one or more add-ons (please see below).
Highlights
- Max Wavelength range 200 to 1100 nm
- Fast measurement of Radiance
- Radiometric software JETI LiVal is included in the standard scope of delivery
- Optical bandwidth 4 nm (can be increased to 2 nm by adding the HiRes add-on, only available for VIS wavelength range)
- Measurement in Radiance (basic configuration) and Irradiance mode (diffusor required)
- Start of measurement with external trigger signal by adding the trigger add-on
- Can be equipped with LAN connector incl. PoE function by adding the LAN add-on
- Highly sensitive
- Internal target spot laser
- Mechanical shutter for dark signal compensation
- Automatic measurement in selectable time intervals
- USB-C
- Bluetooth (standard, can be replaced by LAN connector, see LAN add-on)
specbos 2501 can be customised to your needs
Please add one or more of the following add-ons to configure specbos 2501 according to your requirements:
-
HiRes
Increases the optical resolution (FWHM) from 4 nm to 2 nm in VIS and 3 nm in NIR/UV -> specbos 2501-HiRes
Can be combined with specbos 2501 -
LAN
Bluetooth interface replaced by LAN interface with PoE function -> specbos 2501-LAN
Can be combined with specbos 2501, 2501-NIR, 2501-UV -
focus
Necessary, if the device is to be used with an Add-on optics -> specbos 2501-focus
Can be combined with specbos 2501, 2501-NIR, 2501-UV -
trigger
Enables the possibility of a hardware triggered measurement -> specbos 2501-trigger
Can be combined with specbos 2501, 2501-NIR, 2501-UV
