CIVIT-ICO: Spectral response measurement system

Customized Labsphere QT-1100 Quantum Tunable Irradiance/Radiance Calibration Source

Measurement and calibration use cases for CIVIT-ICO’s spectral response measurement system include color calibration, color uniformity calibration, and Photo Response Non-Uniformity (PRNU).

Light Source Specification:

  • Wavelength: 350 nm to 1300 nm
  • Spectral Bandwidth (FWHM): 5 nm to 10nm
  • Minimum Step Interval: 1 nm
  • Wavelength Accuracy ≤ 0.6 nm 
  • Exit Port Aperture Diameters: 20 mm, 22 mm,  24 mm, and 26 mm
  • Sensor/module test field of view: 68° to 170°
  • Temporal Stability of Radiance: <1% over 1000h

Cameras embedded in Android devices, camera modules with MIPI interface, and any (remote-controllable and exposure adjustable) cameras that can capture raw images.

We provide automated scripts to measure devices. For integrating new devices, we may need scripts for capturing images and converting raw image to .png/.jpg.
