Compact Size Modular Detectors

Modular light detectors are designed for stand alone use or combined with optics and mechanical components to form a complete light detector assembly set-up for a particular application. A compact size T type housing allows accessory components such as optical filters, integrating spheres, diffuser windows and other front-end optics to be easily attached and interchanged.

The VL-1101 detector offers a compact package with flange mount that allows arrangement of discrete linear arrays (11 mm grid size) to measure the luminous intensity distribution of spot lamps. The detector can be combined with integrating spheres with 11- type adapter for luminous flux measurements. Calibration is offered with or without accessory. The detectors are supplied with a 2m long coaxial cable with selectable -1, -2 or -4 type connector for use with Gigahertz-Optik's range of optometers. Internationally traceable calibration & certification of illuminance in lux and UV irradiance in Wm and W/cm within the specified spectral sensitivity range is provided.

The PD-11 series modular detectors are primarily designed to be used in combination with Gigahertz-Optik integrating spheres. A typical application example for sphere based detectors is the measurement of radiant power of lasers, laser diodes and other monochromatic light sources. The PD-11 detectors offer a compact package with flange mount to allow direct mounting to all spheres with 11-type port adapters. Arrangement of discrete linear arrays with a grid size of 11 mm are also possible. Calibrations are offered with or without accessory.
