SPM068 Response Curve

 

SPM Detector

SPM068/QNDS3/R This photomultiplier detector with built-in power supply is fitted with our narrow field of view optic

allowing geometrically accurate radiance measurements in very low light level applications such as bioluminescence, phosphorescence, safety marking, and photon counting. The minimum spot size at a 1-inch distance is 25.4 mm in diameter. This detector is not typically recommended for contact luminance measurements due to secondary reflection characteristics. The detector comes equipped with a QNDS3 attenuator to prevent overexposure of the detector but it may be removed for ultra-sensitive light measurements. The detector has two gain modes - high and low - to vary the dynamic range to suit the measurement application. Calibrations in W/cm2/sr with and without the QNDS3 are provided.

W Cosine

Please note: Care must be taken not to expose this detector to direct room or sunlight signals with the QNDS3 attenuator removed while the detector is connected to the meter to prevent irreparable damage to the photomultiplier tube.
 

Dynamic Range: With QNDS3: 1.37e-11 to 1.37e-4 W/cm2/sr (high gain mode) or 1.69e-9 to 1.69e-2 W/cm2/sr (low gain mode). Without QNDS3: 1.37e-14 to 1.37e-7 W/cm2/sr (high gain mode) or 1.69e-12 to 1.69e-5 W/cm2/sr (low gain mode).

Field of View: ± 0.75 °

Measurement Range: 320-780 nm
Dimensions: 167 mm x 42 mm dia.
