More info

We offer specially for radiometry and photometry designed Current-to-Voltage Amplifier for use with Photodiode-Based Detectors. In other words, our transimpedance amplifiers are optimized for photodiodes.

In our product selection we offer transimpedance amplifiers as standalone devices with data acquisition, display and digital interface which we call Optometers. The listed transimpedance amplifiers differ in number of channels, linear or logarithmic amplifiers, amplification ranges, response time, noise level and maximum current allowed.

We are happy to support you to find the best fitting transimpedance amplifier system for your needs.
