Thorlabs offers a variety of detectors designed for imaging systems. PMT detectors allow for additional detection channels in multiphoton or confocal microscopes. Silicon photomultipliers are hypersensitive detectors for low light applications. Power sensors with the same dimensions as a microscope slide makes measuring the power at the sample possible. Options are available for low-power, high-power, and multiphoton applications. We also offer a selection of balanced detectors specifically designed for OCT applications.
