DATASHEET Lighting Imaging Telecom Sensors IN A RY Channel Photomultipliers and Modules IM PR EL MP 96X-2/ MP 97X-2 CPM Module Single Photon Counting Module for Particle Measurement Description The Photon Counting module series MP96X-2 / MP97X-2 is specially designed for particle measurement with 530 nm and 632 nm lasers. Based on the standard multialkali photocathode, the sensitive diameter is reduced to 2mm in order to achieve an excellent low dark count performance. With an optional SMA adapter, also a fiber read out is possible. The MP96X-2/MP97X-2 series satisfies by exceptional low after pulses. It is an easy to use module, containing the Channel Photomultiplier, a high voltage power supply, a discrimination amplifier and a pulse shaper for fast output pulses. An installed active quenching system avoids over- illumination to the detector. Features · Specially selected for best performance @ 530 nm / 632 nm · Low dark counts · Very high stability in noise level · Exceptional low after pulses · Extended red sensitivity · No cooling required · Active quenching circuit for high light protection · Optical fiber read-out possible · 5 volts operating voltage . w w w. p e r k i n e l m e r. c o m / o p t o Technical Specifications Performance Characteristics Spectral response 100 Quantumefficiency (%) 10 C 963 1 C 973 C 972 C 962 0,1 100 200 300 400 500 600 700 800 900 Operating Specifications Supply voltage Input current at max. count rate Settling time Over-illumination protection: Linear count rate: Output pulse: Active Quenching Control Output pulse width GATE voltage Vgate 5 V dc < 280 mA < 1s (time to stabilize HV after supply voltage applied) active quenching control (internal) 5 MHz TTL, positive TTL-Pulse, active high, RESET:internal via timer, typ. 2,5 s, external via 5 V-pulse 15 ns, (opt. 130 ns) 5 V: h to l set time Vca to Vch-ent +100 V : ~ 150 µs 5 V: l to h set time Vca to Vch-ent - 100 V : ~ 150 µs +5.5 V 5 to 40 °C -20 to 50 °C ~ 350 g Wavelength (nm) Count Rate Linearity 1E+8 1E+7 1E+6 Counts 1E+5 1E+4 1E+3 1E+2 1E+1 1E+0 1E-18 1E-17 1E-16 1E-15 1E-14 1E-13 1E-12 1E-11 1E-1 Light intensity [ W @ 410 nm ] Maximum ratings Input voltage Operating temperature Storage temperature Weight Connections Dimensions (mm) Red: Black: Coax: Yellow: Green: Vcc, input (+5 V to +5.5 V DC) GND External Gate in (TTL,active high) Monitor voltage output (|Vch-ent /1000|) Control voltage input via ext.

Extreme care must be taken to ensure operator safety and to avoid damage to other instruments. Avoid direct contact with the entrance window of the built in CPM when high voltage is applied. Avoid placing conductive material close to the cathode. Ensure that no light levels are applied, generating higher anode currents than specified.
