The D7 diffuser serves a very broad spectral area and is universally applicable.

Spectral Range of use: 200-1100nm
Typical f2' calibrated: 0.75
Max. f2' calibrated: 1.0

Standard D7 Diffuser with horizontal fibre output.

Spectral Range of use: 200-1100nm
Typical f2' calibrated: 0.75
Max. f2' calibrated: 1.0

Environmentally protected D7 Diffuser for out-of-doors measurements. This Diffuser is always accompaniedby a dry-air recirculation system to prevent condensation on the quartzdome.

Spectral Range of use: 200-1100nm
Typical f2' calibrated: 1.5
Max. f2' calibrated: 2.0

All D7 Diffuser variants can be supplied with SMA connectors.

Whilst there is a great selection of compact array-based spectroradiometers in the market, there is a lack of good diffusers for use therewith. The D7, equipped with SMA connectors, is perfectly suited for universal measurements with such devices.

Typically the cosine error of such devices is around 1.5%. The maximum cosine error will not exceed 2.0% (this also implies a D7-SMA-ENV).
