spectraval 1501-HiRes

High resolution spectroradiometer

 
Please note that all models of spectraval 1501 are no longer available since January 2025. The new specbos 2501  models cover all spectraval 1501 applications. 

The high-resolution spectroradiometer JETI spectraval 1501-HiRes was especially developed for the measurement of RGB laser projectors and displays. It has an optical resolution of more than 2 nm, so it allows a precise measurement of narrow bandwidth spectra. Its sensitivity is lower as of the standard version, but this is not significant in case of such light sources.

Highlights

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

Optical parameters
  • Spectral range:         380 … 780 nm
  • Optical bandwidth:   2 nm
  • Measuring range:    
    • Luminance 0.2 … 180 000 cd/m² (Illuminant A)
    • Luminance 0.2 … 140 000 cd/m2 (typical warm white LED)
      (higher values with optional filter)
Measuring quantities
  • spectral Radiance
  • xy and u' v' coordinates
  • Dominant wavelength, Color purity
  • Correlated Color Temperature (CCT)
  • CRI, CQS, TM-30
  • Circadian metrics, PAR

All accessories of spectraval 1501-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 1501-HiRes measures in spectral Radiance mode. It is possible to convert it into a spectral Irradiance meter by attaching a diffusor.

Dolby/realD filter cap pairs
The calibration of 3D projectors needs to be done through the right and left eye glasses. spectraval 1501-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.

On request.

July 07, 2023: Hannu pro (Latvia)
Hannu pro Hannu pro is one of leading system integrator companies in Europe with more than a 30 years of experience in TV, broadcast, production and postproduction system development.
Hannu Pro decided for a JETI spectraval 1501-HiRes to equip the Latvian National Broadcasting Company.
We have sent the device to Tallin today.
