5.2" Fizeau Transmission Sphere Line
XONOX 4+
5.2" Transmission Sphere Line for 4" interferometers
for use on 4" Interferometers
providing extended measuring range
f/0.7 – f/9.25.2" transmission sphere line for 4" systems

Highlights
Built for the production floor.
- innovative, high quality Fizeau interferometer with high resolution 5MP camera and separate 1.6MP alignment camera
- 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 to an 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 many 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
