Optical Design

Ronian received his B.S. in Optics and B.A. in Physics in 1997, and a M.S. in Optics in 1999, from the University of Rochester. He has more than 25 years of professional experience, and his optical designs have included objectives, eyepieces, x-ray-to-visible digital imaging relays, machine vision and classical illumination optics, and fluorescence detection systems for DNA analysis (such as real-time PCR and digital PCR).

Read Ronian's slides on the Basics of Optical Systems in Real-Time PCR instruments for virus detection, which he presented at the XLIV OSI Symposium on Frontiers in Optics and Photonics (FOP) 2021! FOP 2021 was organized by the Indian Institute of Technology Delhi on occasion of the inauguration of the IIT's new Optics and Photonics Center.

Check out Ronian's air-spaced spherical doublet lens design generating uniform "top-hat" illumination from a small incoherent disk Lambertian source:

Applying the technique from above and generalizing to extended sources, Ronian derived a five-element spherical-only lens design producing uniform top hat illumination from a large (9 mm diameter) white LED:
