camera range.
**TI means Texas Instruments Japan
***TC283 was the first Impactron (EMCCD) sensor launched by Texas Instruments but
it was severely flawed in terms of excessively high clock induced charge noise.
Subsequent TI Impactron sensors TC285 and TC247, have shown vast improvements in
this specification and are highly recommended for cell microscopy applications.
**** Gain ageing refers to the mechanism whereby the EM multiplication gain falls
off due to excessive use of EM gain and/or passing excessive amounts of charge (amplified
signal) through the EM gain register. This effect is much more pronounced in sensors
from E2V. However, for E2V sensors, Andor have taken measures to minimize the rate
of gain ageing and to provide user initiated auto-recalibration of aged sensors,
thus providing an extended quantitative service without need for factory recalibration.
