spectraval 1511-HiRes

High resolution stand alone spectroradiometer

The high-resolution spectroradiometer JETI spectraval 1511-HiRes measures fast wavelengths and spectral Radiance. Additionally, it enables an accurate measurement of narrow bandwidth spectra because the device has an optical resolution of better than 2 nm. The spectroscopy instrument was developed for the measurement of RGB laser projectors and displays. The sensitivity of the device is lower as of the standard version, but this is not significant in case of such light sources.

Spectroradiometer JETI spectraval 1511-HiRes

Highlights

  • Compact solutions
  • Fast measurement
  • Measurement in Radiance (basic configuration) and Irradiance mode (optional diffusor required)
  • Precise results due to high quality spectrograph and NIST traceable calibration
  • Comfortable handling due to Bluetooth connection
  • Radiometric software JETI LiVal is included in the standard scope of delivery

 

Thanks to the integrated display, spectraval 1511-HiRes can be operated independently of a computer. The power supply is provided by batteries.

All accessories of spectraval 1511-HiRes are coded. The software switches to the related measuring mode and the appropriate calibration data will be used when an accessory was attached to the device.

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

Standard diffusor
spectraval 1511-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. spectraval 1511-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.
