Description
The VL-1101 is a modular photometric detector designed for integration with optics and mechanical components to form complete light detection assemblies. It is compact, with an 11mm diameter, and can be used with Gigahertz-Optik integrating spheres for total flux measurements or as a monitor detector. The detector features an accurate CIE V(λ) spectral match and can be extended for luminance measurements with the PD-11Z-01 front lens. Calibration is available through Gigahertz-Optik’s Calibration Laboratory.
