Photonics instruments and design software

JEK Systems

Detectors, electronics and lab hardware for optics, and a simulator to design the bench first.

Amplified and biased photodetectors, RF filters, custom RF lenses, control systems, optical mounts and sample holders; custom optical, electronic and mechanical design when the catalogue has no answer; and JEKray, the free optical bench simulator that runs in your browser.

JEKray: lay out an optical system, trace it, and see the waves as well as the rays.
