Lunt Optical Systems is one of the worlds largest manufacturers of precision Fabry-Pérot Etalons.

Having made 10s of thousands of etalon systems in sizes up to 160mm, we are the industry leader in the mass production of precision plano optics.

A narrowband Etalon requires ultra flat optical surfaces of 1/50th of a wave or better.

Lunt Optical Systems are pleased to announce that we will now be offering standard "stock" plano optics and related optical systems.

EdgeSpec (tm) precision optical flats will be offered in sizes from 25mm to 1300mm sizes.

We invite you to test one of our optical flats and compare with what you are currently getting. Our optical flats offer larger clear aperture, smoother surfaces, and economical price points.

OEM's and custom requests are welcome.
