Integral Spheres

Integrating spheres are used to measure the intensity of light emission in many applications.

Description

 

Integrating spheres are used to measure the intensity of light emission in many applications. The units of measurement depend on the type of calibration :

 

  • IRRAD-CAL (irradiance) in watt/m2 or lumens/m2

  • RAD-CAL (power or flux) in watts or lumens

Key Points

  • Entry and exit of integrating spheres :

The IC2 integration cube (5cm) integrates a sphere. It has a 1.6cm inlet and an SMA fiber output. An SMA fiber input can also be used for reflectance measurements. The IS6 integrating sphere (15cm) has a 5cm inlet, an SMA fiber output and a white internal coating.

  • Simple installation of integrating spheres :

The IS12 integrating sphere (30cm) opens and allows simple installation of light measuring devices. It includes a lamp and data files to calibrate the system for luminous flux measurements (in W/nm or lm/nm).

 

The current calibration is carried out by our partner StellarNet according to the NIST standard.
