Features:
- Compatible with All Kinds of Photodiodes
- Front Panel Operating Elements
- 5-Digit LED Display
The Thorlabs PDA200C is a precise photodiode current amplifier compatible with all kind of
photodiodes. After a calibration the PDA200C can be used as precise optical power meter.
Typical applications of the PDA200C are: simple operation of photodiodes (transimpedance amplifier), sensitive pico-Ampère meter, low noise amplification of photodiode current, and simple optical power meter.
The PDA200C is easy to operate via the operating elements on the front panel. The operating parameters are shown on an illuminated 5-digit LED display. Either PD-current, optical power or bias voltage can be displayed. The displayed parameter is chosen by up / down toggle switches and indicated by LEDs. The units of the measurement for current and power ranges are indicated by LEDs. The unit for bias voltage is V.
The offset of the input amplifier and of the photodiode can easily be adjusted using a 12-turn potentiometer.
The bias voltage ranging from 0 V to +10 V (for polarity anode grounded) or from 0 V to -10 V (for polarity cathode grounded) can be applied to the photodiode using the sliding switch on the rear panel of the PDA200C. The voltage is set using a 12-turn potentiometer.
The displayed power values can be calibrated for a known power level by a potentiometer.
The Analog Out provides a DC voltage proportional to the photodiode current.
The installed mains filter and the transformer shielding provide a low ripple at the analog control
output.
The PDA200C ThorLabs Photodiode Amplifier may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
