Photodetector

KT-PR Series Preamplified Photodetector Module Integrated high-speed response PIN detector and low noise amplifier, fiber or free space coupling, SMA connector output, with high gain, high sensitivity, flat gain, etc., providing multiple frequency ranges from 200KHz to 2GHz, mainly used for analog optical signals Receiving and optical fiber sensing systems and other fields.

SPCM-APD series Single Photon Counting Module APD operated in the Geiger mode, are used to detect single photos over the wavelength range of 350nm to 1060nm. The SPCM-APD series has been developed to offer a unique combination of high quantum efficiency, wide dynamic range and ease of use for photon counting applications.

The photomultiplier tube is a photoelectric conversion device that can convert weak light signals into electrical signals. It can increase the incoming weak light signals by 106 to 108 times. Dynode pho-tomultipliertubes can be divided into head-on type and side-on type according to the angle of incident light.

The KT-BPR series 20G Balanced Photodetector Module integrates two 20G high-speed balanced detectors and a low noise amplification circuit. It has the characteristics of low noise, high gain, and high sensitivity, which can effectively reduce the common mode noise of input light and improve the signal-to-noise ratio of the system. The bandwidth can reach up to 25GHz. The 220V adapter and+12V adapter are optional for power supply, making it convenient to use. Mainly used in the fields of coherent

The KT-BPR Series Balanced Photodetector Module integrates two matched photodiodes and an ultra-low noise mutual resistance amplifier, effectively reducing noise.
