Determination of radiant power or luminous flux from light sources with the aid of integrating spheres is one of the most important procedures in photometry. Designed as a hollow sphere whose inner surface is coated with a diffusely reflecting material, the integrating sphere ensures complete integration and mixing of light radiation. This is then output on a detector port for measurement.

The standard test temperature is 25, but high power lamps such as HID lamps and LED outdoor luminaires will produce a lot of heat during the test, thus the temperature inside the integrating sphere can not meet the requirements of IEC standards. Lisun Group designed the Constant Temperatured Integrating Sphere which allows the lamp was tested in a constant air temperature.

Integrating spheres are used especially for measuring divergent light sources such as LEDs. The light is introduced through the input port, then reflected many times by the highly reflective interior of the sphere until it illuminates the inner surface uniformly. A detector samples a small fraction of this light to measure the total power input. Ophir integrating spheres have a highly reflective diffuse white coating for measurements independent of beam size, position and divergence. There are several sphere sizes, apertures and wavelength regions available. The large IS6 series has 2 configurations for measuring divergent or parallel beams.

The simpler way to measure the total luminous flux of lamps and luminaires is to use an integrating sphere photometer system. It is a device to perform spatial integration of flux optically, thus the total luminous flux can be measured with one fixed photometer head and measurement can be instant. An integrating sphere photometer is calibrated with a total luminous flux standard lamp. A test light source is measured by comparison to a standard lamp calibrated for total luminous flux.

Artifex Engineering GmbH & Co. KG
We offer integrating spheres made from a special polymer suitable for the wavelength range 250nm – 2.5 µm. For longer wavelengths in the range 700nm – 20 µm, a gold coating on a rough, metallic surface is used. Since lasers in this spectral range are usually also high power, we use solid copper as a thermally conductive substrate material. By choosing the size of the integrating sphere, the overall sensitivity of the system can be adjusted. In addition, the detector is independent of inhomogeneities in power density and polarization. The detector is also independent of the incidence location and angle of the laser radiation.

All our spheres can be coupled to our high performance spectroradiometer systems for UV-visible-IR spectral power distribution measurements yielding full colour information including colour rendering indices, chromaticity co-ordinates, colour temperature, etc. Alternatively precision photometric detectors can be fitted for direct total lumen output measurements.

The integrating sphere is used for total luminous flux measurement. It uniforms the light by spatially integrating the collected light of light source. The integrating sphere has highly reflective diffusing plates formed on the spheres internal surfaces. These plates repeatedly scatter light rays from the light source with in the sphere to all other points to deliver uniform brightness distribution so measuring a portion of that light gives the total luminous flux. These years, the usage of integrating sphere for total luminous flux evaluation of light source is increasing. The large size integrating sphere over 1.5M is required for measuring a high brightness light source and a long light source such as fluorescent light.

An integrating sphere is a light collector which takes advantage of physical geometry to homogenize any radiation being emitted inside by relying on a high-reflectance coating material. Depending on the wavelength range the end user using a sphere with, different coatings have different advantages based on the application.

General Purpose Integrating Sphere Systems are designed to spatially integrate radiant flux in order to measure optical radiation. The spheres can be coupled with a sensor to create radiometers, photometers, or spectroradiometers in order to measure the total geometric flux emanating from a light source or the flux density of an illuminated area. Additionally, these sphere systems can be used to measure the output of high power lasers and laser diodes or to measure the reflectance and transmittance of materials.
