Reflectance and Irradiance Integrating Spheres
|
|
Integrating Spheres |
The reflectance spheres measure total integrated reflectance from a surface. They have two SMA connectors: one at 90° to connect to the spectrometer, and one at 8° for the illumination source.
For irradiance measurements (i.e. lamp or LED characterization) use the irradiance sphere. This sphere acts like a cosine corrector, but is designed specifically for measuring the irradiance from a directed light source. Use a cosine corrector when measuring 180° irradiance (i.e. room light). |

CRP-IRR Cosine Corrector
|
Cosine Corrector |
For irradiance measurements from widely diverging light sources, use a cosine corrector. The CRP IRR collects radiation from a 180° solid angle. It couples directly to any SMA terminated fiber. The CRP IRR uses a PTFE diffusing material, which is usable from 200 to 1100 nm. It has a 6.35 mm OD barrel dimension. |
