specbos 2501-HiRes

High resolution spectroradiometer

JETI specbos 2501-HiRes is a high-resolution spectroradiometer, which measures fast wavelengths and spectral Radiance. Due to the optical resolution of the device of better than 2 nm, it is possible to measure the narrow bandwidth spectra accurately. The sensitivity of the spectroscopy instrument is lower as of the standard version, but this is not significant in case of such light sources. All other parameters as sensitivity, measuring mode (Radiance) and viewing angle remain the same as of the standard device.
To obtain this device, please order a basic model specbos 2501 plus the HiRes add-on. You can find more add-ons to customise your 2501 according to your needs here.

    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

Measuring quantities
  • spectral Radiance
  • spectral Irradiance by attaching an optional diffusor
  • xy and u' v' coordinates
  • Dominant wavelength, Color purity
  • Correlated Color Temperature (CCT)
  • CRI, CQS, TM-30
  • Circadian metrics, PAR

JETI specbos 2501-UV can detect up to four accessories automatically, the software switches to the related measuring mode and uses the appropriate calibration data. More accessories have to be selected manually in the software.

Add-on optics for different measuring geometries
JETI offers a variety of add-on optics to achive certain different measuring geometries.

Add-on optics for measurement of VR/AR glasses
JETI offers add-on optics to perform measurements of VR/AR glasses. These optics are only available for JETI specbos 2501 (equipped with focus add-on).

Standard diffusor
JETI specbos 2501-HiRes measures in spectral Radiance mode. It is possible to convert it into a spectral Irradiance meter by attaching a diffusor.

In axis remote diffusor
If the measurement needs to be done in locations with limited space conditions then the remote diffusor can be used. It is a diffusor which is coupled to the spectraval device by an optical fiber bundle. The measurement is done in axis to the fiber bundle. Different fiber lengths are available.

90° remote diffusor
If the measurement needs to be done under limited space conditions and the in axis fiber coupled diffusor is not suited, then the 90° fiber coupled diffusor can be applied. Different fiber lengths are available.

Dolby/realD filter cap pairs
The calibration of 3D projectors needs to be done through the right and left eye glasses. JETI specbos 2501-HiRes can be equipped with caps containing the filters of Dolby and realD projection. The usage of these filter pairs allows a precise measurement of 3D projections.

Battery charger

Bluetooth USB adapter

Carrying case/ bag

Protective cap

Straylight protection tube
The straylight protection tube prevents the influence of surrounding light on Radiance measurements. It is mainly used for display measurements.

Tripod

Stray light correction matrix
In order to reduce stray light in array spectroradiometers while taking advantage of their portability, JETI offers a stray light correction matrix.
