“Customers now have the option to specify microlensing for their SPAD array camera,” according to the company. “The microlenses offer an improvement of more than 10x in effective fill-factor, enhancing the sensitivity of the camera for time-resolved measurements. This works well for low light applications such as imaging through scattering media, as well as for fluorescence microscopy.”
The cameras work at hundreds of thousands of frame/s and have picosecond timing resolution.
The microlens is an array of lenses matching the 32 x 32 pixel array, and these lenses direct more light to the sensitive areas of each pixel, diverted from that which would have fallen on the support circuitry in each pixel.
Launched in 2015 and based in Edinburgh, Photon Force is a spin-out from the the University of Edinburgh’s CMOS sensors and systems group. In addition to the PF32 camera range, it offers the custom design and manufacture of sensors, modules and boards for research projects and product development.
