X-mini Objectives – X-mini Objective Line

Highlights

Built for the production floor.

compatible with XONOX X-mini - phase shifting Twyman Green style interferometer
infinity corrected design
very affordable and cost efficient
industry standard M26 x 0.7 interface
selection provides excellent coverage for the measurement of spherical surfaces 13mm (0.5") and smaller (many more compatible objectives are commercially available)
high quality reference surface is supplied for objectives
software supported calibration on X-mini Interferometer system
X-mini system accuracy is λ/20 PV due to integrated reference and advanced system error compensation via XONOX X-fringe phase shifting analysis software
for testing flat surfaces of diameter 20mm and smaller, there is no objective required
small form factor

Selector

Which objective fits your surface?

Enter the radius of curvature and the clear aperture of the surface you want to test. The selector recommends the slowest objective of the X-mini Objectives line that still covers the full aperture.
