Description
PerkinElmer Optoelectronics’ Channel Photomultiplier (CPM)
is an ultra-high sensitivity optical detector capable of replacing
conventional photomultipliers (PMTs). This device uses a proprietary
detector principle to produce ultra-high gain and dynamic range,
extremely low noise, and fast response within a compact form
factor. These detectors are available as components or in complete
modules designed for DC operation and photon counting. All
modules are gateable by an external TTL pulse for time-resolved
measurements.
Modules
• MD Series DC-Module—contains the CPM, a high-voltage
• MP Series Photon Counting Module—The Photon Counting
• MH Series Channel Photomultiplier Head Module—The
• MP 96X-2, MP 97X-2 Single Photon Counting Module—
Power Supply
• CHV 30N—A self-contained high-voltage supply specially
• CHV 30P—The equivalent power supply for positive high voltage.

Principle of Operation
The CPM converts a very low light level into photoelectrons
through a semitransparent photocathode deposited on the inner
surface of the entrance window. On their way from the cathode to
the anode, the photoelectrons pass through
a narrow semiconductive channel. Each time the
electrons hit the inner surface of the curved channel, multiple sec-
ondary electrons are emitted. This effect occurs multiple times
along the path, leading to an avalanche effect with a gain exceed-
ing 10
tion effect.
power supply, an amplifier with I/U conversion, and an active
quenching circuit for high light protection.
Head MP 900 contains the Channel Photomultiplier, a high-
voltage power supply, a discrimination amplifier and a pulse
shaper for fast output pulses.
Channel Photomultiplier module MH 900 series is designed
for both photon counting and dc operating modes. It contains
an adjustable high-voltage supply and a Channel Photomulti-
plier of the C900 series.
These modules are specially designed for particle
measurement with 530 nm and 632 nm lasers. Based on the
standard multialkali photocathode, the sensitive diameter is
reduced to 2 mm in order to achieve an excellent low dark-
count performance.
designed for the Channel Photomultipliers CPM C900, C1300
and C1900. It provides the matching voltages for the cathode,
channel entrance, and channel end.
