Functionality
The IS200 Integrating Sphere is a general purpose integrating sphere enabling high sensitivity measurements of optical signals. An Integrating Sphere evenly spreads the incoming light by multiple reflections over the entire sphere surface. This makes it the ideal instrument for many applications such as laser power, flux, reflectance and radiance measurements. The Input and Output Ports can be equipped with fiber adapters or closed with the coated Port Plugs (included); the Detector Port is recessed to avoid direct light exposure from the incidental light to the active area of the photodiode. The sphere is manufactured from PTFE based high reflective bulk material which is highly reflective (250 - 2500 nm) and is resistant to heat, humidity, and high levels of radiation. The sphere is compatible with Thorlabs' SM05 (0.535"-40) thread standard as well as our 30 mm cage systems, thereby enabling easy integration into existing setups.

Our IS200 Integrating Spheres are available with either a mounted Si photodiode (350 - 1100 nm), mounted InGaAs photodiode (800-1700 nm) or without a detector. When purchasing an Integrating Sphere without a built-in detector, the sphere's operating range is limited by the reflectance wavelength range of 250 - 2500 nm (see the Specs tab). When purchasing the sphere with no detector, any of our SM05PD family of detectors can be mounted to the Ø3 mm detector port using the SM05 threading of the included SM05 Adapter (SM05L05).

Replacement items for the included adapters and port caps can be ordered separately below.

Choose from 5 Models:

  • IS200 & IS200-4: Ø2" Integrating Sphere with 3 or 4 Ports and without a Detector
  • IS236A & IS236A-4: Ø2" Integrating Sphere with SM05PD1B Si Detector (350 to 1100 nm) and 3 or 4 Ports
  • IS210C: Ø2" Integrating Sphere with Anode-Grounded Version of the SM05PD4A InGaAs Detector (800 to 1700 nm) and 3 Ports

For our integrating spheres we offer a calibration service upon request. Please contact your nearest sales office for more information.

Please note that inhomogeneities at the edges of the active area of the detector can generate unwanted capacitance and resistance effects that distort the time-domain response of the photodiode output. These effects are observabled when the diode is overfilled. If these effects are detrimental to your application, please contact Technical Support for further assistance.
