Optical Trap Detectors

For the first time anyone can cross calibrate their optical power meters against a reference detector for which the responsivity is determined by such fundamental constants as the charge of the electron, Planck’s constant and the speed of light.

Our Optical Trap Detectors are based on concepts originally developed at the National Institute of Standards & Technology and are the first commercially available Optical Trap Detectors. They exhibit a Quantum Efficency of >99% and are available for both collimated (NA <0.12) and diverging sources (NA <0.24).
