Amplifier AMT-07M converts the output current of a signal source
(such as Mid-Infrared photodiode) intoa voltage with
amplification for subsequent use with various electronic
systems, such as lock-in amplifiers, oscilloscopes or A/D
converters. Synchronous detector is built in the same package
and gives direct current proportional to signal at selected
frequency. Signal value is viewed on LCD Display.
Amplifier AMT-07M is oriented for operation with photodiodes with built-in thermocooler and thermistor (LmsXXPD-TEM(-R) models). Customer can select and set PD operation temperature. Circuit with feedback will set the appropriate thermocooler current for maintaining the selected temperature.
** AMT-07M models will be replaced with newer unpackaged device versions soon
|PAb preamplifier is oriented for amplification
and conversion of the pulse current signal generated by LMSNT
photodiodes (PDs). Preamplifier enables PD operation at
photovoltaic mode (with no reverse bias) – mode in which
photodiode becomes the source of photocurrent. PD photocurrent
is amplified and converted by preamplifier into voltage signal.
