They are ideal for precise optical measurements, laser and photodiode characterization, lifecycle measurements and many more applications in the lab and on the manufacturing floor. The dual channel design enables differential and ratiometric measurements. Intuitive manual operation with the large graphics display, compatibility to conventional photodiodes, and excellent remote capabilities enable easy system integration. The PM300 is compatible with all Thorlabs S100 Series Photodiode Sensors (two channels) and S200 Series Thermal Sensors (one channel) and allows the connection of unamplified anode or cathode grounded photodiodes with up to 10mA photocurrent and thermal elements with up to 100mV output voltage. The PM300E additionally offers energy measurements with all Thorlabs ES100 and ES200 Series Energy Sensors (both channels) and dual-channel measurements with the S200 Series Thermal Sensors as well. Both the PM300 and PM300E Series are sold as a single benchtop device with the sensors ordered separately. It can be combined with any of our power meter sensor heads, or user-supplied photodiodes that provide a maximum 10mA output. The PM300E Series is additionally compatible with all ES100 and ES200 Series Pyroelectric Energy Sensors. Functionality The calibrated sensors connect via two sub-D connectors on the rear panel, which also provides two analog high bandwidth outputs to allow monitoring of each channel, plus the programmable analog output. Optional user-supplied photodiodes connect via two BNC inputs on the front panel, which feature switchable bandwidth and a programmable bias voltage. The input can be switched between the front and rear connectors. The additional BNC output is gain- and-function programmable. It provides an analog voltage proportional to the output of one of the channels or as a difference or ratio of the two power meter channels. The measurement resolution is 16 bit for all power ranges. The PM300 and PM300E Series are controlled locally via the front panel, which features a large 240x128 pixel LCD display, or remotely via USB 2.0.
