LINEAR MULTIANODE PMT MODULE H12310-40/-42, H12311-40/-42 OVERVIEW The H12310 series is a GaAsP photocathode 16-channel linear multianode PMT module. Its output can be adjusted by controlling the gain of each channel individually. The H12311 series is a PMT module consisting of a H12310 series and a cooler installed to the built-in PMT. FEATURES ●Gain can be adjusted individually for each channel ●Reduced dark noise due to cooling effect (H12311-40/-42) Left: H12310-40, Right: H12311-40 with heat sink A14473 and fan A14474 (sold separately) ●Biomedical fluorescence detection ●Laser scanning microscope ●High speed spectrophotometer Figure 2: Typical gain Figure 1: Typical spectral response CATHODE RADIANT SENSITIVITY (mA/ W) QUANTUM EFFICIENCY (%) CATHODE RADIANT SENSITIVITY QUANTUM EFFICIENCY 0.1 200 Figure 3: Voltage output in darkness ●Before cooling Example: H12311-40 ●After cooling Example: H12311-40 LOAD RESISTANCE: 1 MΩ LOAD CAPACUTANCE: 15 pF CONTROL VOLTAGE: +1.0 V LOAD RESISTANCE: 1 MΩ LOAD CAPACUTANCE: 15 pF CONTROL VOLTAGE: +1.0 V INPUT CURRENT TO THERMOELECTRIC COOLER: 2.8 A (THE HEAT SINK WITH FAN IS USED.)
