About us

Who we are

OptArc is an optical instruments design, prototyping and manufacture company. Our CEO and founder is Dr Paul J. Tadrous, a UK-based medical histopathologist (now retired from clinical practice) who has been working in specialist microscopy and optics since the 1990’s. In addition to working in the NHS for over 26 years, Dr Tadrous is an author and has a Ph.D. from Imperial College London having worked in the Applied Optics departments both there and also in the University of Kent at Canterbury.

What we do

OptArc was set up to make high quality optical instruments and related supplies available to the general public, using 3D printing to make prices affordable to those without huge research grants. We specialise in:

  • 3D printed optical instruments
  • Microscopes including the open source PUMA system
  • Cameras specially suited for use with microscopes and telescopes
  • Supply of components, equipment and reagents for microscopy and digital imaging
  • Custom software production for our products

Our business

We are a small business based in Harrow, Middlesex, England (UK) where we have our 3D printing lab and optical works. To keep costs to a minimum, and because of the specialist nature of our services, we have no high street presence: we supply direct from our workshop to customers via this online web portal.

We 3D print, assemble, test and calibrate our bespoke systems right here in the UK which is where all our stock is shipped from.
