PD300-CIE
The PD300-CIE head has a spectral response similar to that of the human eye and therefore is
calibrated to measure in eye response units of Lux. The PD300-CIE is designed with a small
detector in which the source overfills the detector. It displays the light intensity per unit area in
units of Lux or Foot Candles.
Differences between PD300-CIE and Standard Photodiode Sensors
Except for the following differences, PD300-CIE behaves exactly like a standard PD300:
Measuring Mode can be set to Lux or Foot Candles (Lx or Fc).
Wavelength Selection is disabled.
Filter Selection is disabled.
The Density and dBm functions should be disabled (after discussion with Ephraim G).
Other than the above, operation is the same as for other PD300 type heads.

PD300-BB
The PD300-BB is a Photodiode-based sensor with a flat spectral response.
Differences between PD300-BB and Standard PD300 Sensors
Except for the following differences, PD300-BB behaves exactly like a standard PD300:
There is no wavelength selection.
Some models do not have filter selection.

PD300RM
The PD300RM series of sensors are geared towards measuring irradiance and dosage. Like other
sensors in the PD300 series, the PD300RM is based on a Photodiode. However, unlike the PD300
series, it is calibrated to measure irradiance (W/cm²) and dosage (J/cm²) at some distance from a
divergent source. A diffuser is placed over its aperture, thereby eliminating the sensitivity of the
Photodiode to the incident angle of the light. This enables the sensor to be used to measure
irradiance when light is incident on the sensor from different angles.
