Integrating Spheres

Source: StellarNet, Inc.

An integrating sphere’s most important functionality involves its ability to uniformly scatter and diffuse radiant flux, luminous flux, or other types of light emission, off of a sample surface. This is key in measuring the total light radiated in all directions from a lamp or other light source.

Integrating spheres can measure a surface’s diffuse reflectance, or create a light source with uniform intensity over all positions within its aperture. These two functions are ideal for photometric measurements, radiometric measurements, and other types of optical measurements.

StellarNet offers a wide variety of integrating spheres that come in various sizes, input port configurations, mounting options and more.  

Applications include light source characterization of spectral intensity distribution, color temperature, xy chromaticity, dominant wavelength (and more), for LED, laser, solar, industrial lighting, and any type of light emission.

  • IC2 is a 2” cube with internal integrating sphere. It has 5/8” input port and SMA fiber optic output. Another SMA input can be used for reflectance illumination. Select the CR2-TP miniature tripod for mounting the IC2 for alignment and repeatable measurement.
     
  • IS6 is a 6” integrating sphere with a 2.0” input port, 1 SMA fiber optic output, and internal white coating.
     
    - The IS-Lamp is a Calibrated Miniature 10 Watt fiber optic VIS-NIR light source mounted on a 2" port cap, 400-1050nm, NIST traceable. Includes lamp with data file used to calibrate the system for total flux measurements in watts/nm and

             - The IS-SMA is a SMA connector mounted on a 2" port cap with internal white coating. Allows direct connect of SMA terminating optical fibers

             - The IS-RED is a 2" port cap with reduced sized 1" diameter aperture with internal white coating

  • IS12 is a 12” integrating sphere that allows for internal mounting of devices for light measurement such as discrete LEDs, arrays, and bulbs. The sphere opens for simple access to mounting devices. IS12 Sphere includes lamp with data file used to calibrate the system for total flux measurements in watts/nm and lumens/nm.

StellarNet’s integrating spheres are particularly well suited for light source characterization of spectral intensity distribution, color temperature, xy chromaticity, dominant wavelength (and more), for LED, laser, solar, and industrial lighting. Contact them for more information.
