Labsphere Integrating Spheres

Labsphere Integrating Spheres

Integrating spheres simplify complex optical measurements

Integrating spheres were first developed in 1894 as a tool to measure the output of the then newly invented electric light bulbs. Today, our Labsphere integrating spheres are widely used in the measurement of light, as sources of uniform radiance or irradiance for calibrating image sensors, cameras and remote sensing instruments and for testing the optical properties of materials. An integrating sphere is a hollow, spherical chamber coated internally with a high reflectance coating that exhibits diffuse reflectance. Spheres are used as directionally-insensitive collectors of light when combined with photodetectors. An internally illuminated integrating sphere emits a field of spatially and angularly uniform luminance or radiance which is perfect for testing and calibrating imaging systems, detector arrays and remote sensing instruments.

Labsphere's reflectance & transmittance integrating spheres constitute one of the most basic reflectance measurement products and can be used to measure the reflectance or transmittance of a wide variety of sample mediums. Offered in two standard designs, each sphere is available in one of two reflective coatings depending on the spectral range of interest.

  Labsphere's light measurement integrating spheres are designed for the measurement of the total flux output of lamps and other light sources. The LMS integrating spheres range in size from 25cm to 3m diameter, offer a highly reflective, durable Spectralon® or Spectraflect® interior, and can accommodate lamp sizes from single LEDs right up to the very largest street lighting luminaires.

An internally illuminated integrating sphere provides spatially uniform luminance and illuminance which is perfect for flat-field correcting and calibrating imaging systems, calibrating photometers and spectroradiometers and for testing detector arrays and remote sensing instruments. Integrating sphere-based sources exhibit a luminance uniformity at the 98-99% level over the full exit port area, which is significantly higher than can be achieved using alternative techniques.
