5.2″ Fizeau Transmission Spheres

Integrated 30% wavefront expansion turns each standard 4” interferometer virtually into a 5.2” system with 30% larger aperture
No mechanical or optical modification required on existing systems – just mount in existing 4” standard bayonet and start
Fully interchangeable with existing standard 4” TS
Huge added value by up to 60% more coverage of lens surfaces in terms of visible lens aperture and pricing like classical 4” TS
Innovative f/ number line for improved and gap free coverage of much more surfaces for full aperture measurement
High quality optics, mechanics and innovative assembly for long term sealing against dust
Excellent, hand crafted reference surfaces, free of any features caused by machine- or sub aperture polishing
“Smart Case” – the practical, user oriented and safe box- and handling system
Highest quality 100% made at XONOX, Germany
