ITS 500 / 1000 Integrating Spheres – Streamlined measurement of luminous flux

Using integrating spheres to determine the radiant power or total luminous flux of light sources is one of the most important procedures in light measurement. The interior surface of the sphere is coated with a diffuse reflecting material and, thus, ensures complete integration and mixing of the light radiation. This is partially output at a detector port for measurement.

The Optronik Line spheres with diameters of 500 (ITS 500 comply to ECE R37) and 1000 mm (ITS 1000 comply to ECE R37 and R99) are particularly suitable for determining the characteristics of lamps and modules in the automotive, traffic-lighting and aerospace sectors. Three different burning positions (suspended, vertical, horizontal) can be arranged using an adjustable lamp holder, in order to operate each test sample in the intended burning position.

Features:

• Measuring geometry in conformity with CIE 84.
• Barium sulfate coating with 80% reflectance.
• The lamp post can be mounted in a suspended, vertical or horizontal position.
• Integrated auxiliary light source for determining the self-absorption of the sample.
