Thorlabs PM101 very good price

PM101

Photodiode and Thermal Power Sensor Interface with USB, RS232, and Analog Operation

• Compact Power Meter Interfaces with Various Output Connection Options
• Red C-Series Connector for Quick Sensor Exchange
• Ideal for Manufacturing Environments

Features

• Compact Interfaces to Enable PC Control of Power Meter Systems
• Compatible with Thorlabs' C-Series Sensors:
  • PM101 Series: Photodiode and Thermal Power Sensors
  • PM102 Series: Thermal Power and Thermal Position & Power Sensors
  • PM103 Series: Photodiode Power and Pyroelectric Energy Sensors
  • PM100USB: Photodiode Power, Thermal Power, and Pyroelectric Energy Sensors (Except for Item # ES408C)
• Optical Power Monitor PC Software Available (See Software Tab for Details)

These interfaces provide communication between an attached sensor and a PC or other external control unit. They are designed to be controlled via an external device or operated autonomously using the analog output; there are no controls or display screens.

The PM101 series power interfaces are compatible with Thorlabs' C-Series photodiode and thermal power sensors, the PM102 series is suitable for use with our C-Series thermal power and thermal position & power sensors, and the PM103 series is suitable for use with our C-Series photodiode power and pyroelectric energy sensors. These interfaces support several options for control and digital readout, including USB 2.0, RS232, UART, analog output, and ethernet, depending on the model. The PM103 series is able to acquire data with a much higher readout rate of 100 kilosamples per second (kS/s) versus the maximum rate of 1 kS/s of the PM101 and PM102 series. Our PM100USB interface is controlled and provides digital readout via USB 2.0 only and is compatible with Thorlabs' C-Series photodiode, thermal power, and pyroelectric energy sensors, except for the ES408C fast pyroelectric energy sensor.
