The LBTEK biased photodetector series covers three types: Si, InGaAs, and Ge. These detectors combine low noise, fast response, and no gain characteristics, making them suitable for various photodetection applications. They offer excellent performance, with a fastest rise time of only 1 ns, and can directly receive free-space input optical signals. The detector comes with a built-in A23 battery to provide reverse bias. If a power supply is preferred, the DET-12V power kit on this product page can be purchased separately. Using a BNC-BNC signal cable, the signal interface of the photodetector can be connected to an oscilloscope or other data acquisition devices. Additionally, the side of the detector features a red battery check button. Without removing the battery, a simple press allows a quick check to see if the battery needs replacement, greatly improving operational convenience and efficiency.
Note: The product includes an SM1 internally threaded sleeve, which can be removed for use.
