PD-9310 with SRT-M37-L

High sensitive detector head to measure the photopic luminance in cd/m². Features: front lense for 1°, 2°, 5° or 10° viewing angle, for the usage with Optometers and amplifiers, calibration certificate

PD-9310 with SRT-M37-L

Illuminance and luminance measurement 

The PD-9310B-N is detector designed for measurement of low illuminance levels. Because of not having a diffusor window, the PD-9310B-N offer higher illuminance responsivity compared to the PD-9310B detector with diffuser window. The fact it does not have a diffuser window however limits its field of view and only light sources whose extent is within the field of view of the measurement head e.g. spot lamps can be measured. The application potential of the PD-9310B-N can be enhanced using an SRT-M37-L series optical head so as to measure the luminance in cd/m². Since measurement field focusing is hereby not possible, this combination is mostly applicable for extensive illumination fields. 

The SRT-M37-L optical head can be directly screwed onto the front screw of the PD-9310B-N measurement head. 

Optical heads with 1°, 2°, 5° and 10° measurement field angles are hereby offered. 

Traceable calibrations 

Luminance responsivity calibration of the optical head combined with the measurement head is possible. The calibration is performed by Gigahertz-Optik‘s calibration laboratory for optical measurands. Calibration is validated by a calibration certificate.
