The
Olis Photon Counter can be fitted
to the Olis RSM and can be adapted
to fit most instruments. It was recently
fitted to an SLM 8000 and is available
as an accessory to the RSM 1000F Fluorimeter
or the RSM CD with fluorescence capabilities.
A photon counter is used in applications
where you have time for the best emission
signals, as opposed to flash and stopped-
flow cases where collection is over
in <
1-2 seconds.
This photon counter is controlled by
Olis software in coordination with an
electronics box and adapter. The counter
is made with a built in 'cut-off filter'
holder which cuts off a wavelength above
excitation light so all you have is
fluorescence.
Summary
of Specifications*:
- Approximately 26 million photo-electrons
per second
- Covers UV to 650 nm with very
low background noise
- Provides a large, 21 mm diameter
active area for good light gathering
ability
- High speed current pulses are
amplified and converted to digital
pulses with a high speed amplifier
and discriminator
- Precise counting intervals are
provided by the crystal controlled
counter/timer circuitry in the microcontroller.
*All performance specifications are
taken from manufacturer's literature.
