Photodetector Sensor:
- Equipped with a dual 40-element silicon photodiode array sensor.
Spectral Separation Device:
- Utilizes a high-precision planar diffraction grating for spectral dispersion.
Spectral Parameters and Photometric Specifications:
- Wavelength measurement range spans from 360 nm to 740 nm.
- Fixed 10 nm wavelength pitch with an optical half bandwidth of approx. 10 nm.
- Photometric range: 0 to 175%; display resolution: 0.01%.
Integrating Sphere and Light Source:
- Integrating sphere diameter size: Ø152 mm.
