Photon Counter for ultra-low-light applications
		The microprocessor controlled photon counter PC100 was developed for OEM applications with a photomultiplier in the photon counting mode. The unit can be especially used for ultra low light applications in the areas e.g. of chemoluminescence, bioluminescence or flouorescence. All settings can be made directly on the module or however via the serial RS232/RS485 interface with an external computer. The counting result is displayed on the integrated display or transmitted by the interface.
		Features and advantages
		max. counting rate: ... 5 Mcps
		measuring interval: 10 ms ... 5s
		modes: gated or continous
		complete unit dimensions: 200x160x70 mm (LxBxH)
		dimensions of the pcb board: 91 x 61 mm
		good price / performance ratio
		The photon counter PC100 was developed particularly for the adaptation of the Perkin Elmer CPM Channel photomultiplier series MP 900. By this technique the mulltiple secondary electrons are emitted via the impact of the photoelectrons on a curved semiconducting channel. This effect occurs multiple times along the channel, leading to an avalanche effect with a gain exceeding 10exp8. The curved shape of the glas tube improves the multiplication effect. Substantial advantages can be reached by this new technology. One MP 900 module can be connected directly on the back of the photon counter PC100.
		Features of the MP900 channel photomultiplier
		ultra high anode sensitivity up to 10exp7 A/W
		extremely low dark current, typically 3pA
		very low dark counts: typ. 10cps - only thermal kathode emission
		6 decades dynamic range
		different spectral ranges from 165nm ... 850nm
		reliable channel photomultiplier - also for industrial applications
		The photon counter PC100 is supplied also as a simple OEM pcb board version and in combination with a MP 900 photomultiplier.
