ISD-100HF-V04 Integrating Sphere

Gigahertz-Optik offers a range of integrating spheres for total flux measurement of spot type (2π light distribution) and bulb type light sources (4π light distribution).

The 1000mm diameter model ISD-100HF-V04 integrating sphere supports the measurement of both spot and bulb lamps. For spot lamps it offers an application port with 127 mm (5”) free aperture which can be closed with a port plug when not in use. It also features a hinge frame bench-top stand that enables one hemisphere to open/close for mounting the light source under test in the center of the sphere. For positioning different size and shape light sources a height adjustable sample holder is provided. The test lamp socket can be mounted using the threaded hole pattern on the sample holder assembly plate. Gigahertz-Optik offers lamp post type sockets set into the center hole in the assembly plate. The terminal block with four leads enables separated power feed lline and voltage measurement. For error compensation caused by the self-absorption effects of the test sample an auxiliary lamp is available. The quartz-halogen auxiliary lamp generates the proper flux level needed for the substitution correction. A baffle in front of the detector port blocks a 300mm diameter spherical space at the sphere center. Different types of detector holders are available. The barium sulfate coating covers the spectral range of 300 to 2400nm. Optional Gigahertz-Optik light detectors, light meters, light analyzers and calibrations are offered.
