Excelitas products size, map, detect, time, and measure with precision that aids humanity's understanding and research in a broad range of scientific applications in astronomy, life sciences, physics and more. 


Excelitas offers precision lenses used for imaging from the cellular to interstellar. Our detectors are sensitive enough to detect single photons in laboratory experiments or from distant galaxies. And, we offer lasers with the beam profile and stability that ensure the integrity of measured data. 


Excelitas has a long heritage of designing and manufacturing Avalanche Photodiodes (APDs) used in several space surveying missions.


The simplest approach to detect the fluorescence emitted from a biological sample is to image the specimen from a microscope onto a camera.

Physics and Material Sciences

Excelitas lasers, lamps, optics and detection are used for a variety of applications in physics and material sciences.
