Kaleo MTF station
Spectral Range UV (190 - 400 nm) VIS - NIR (400 - 1100 nm) SWIR (900 - 1700 nm)
The Kaleo MTF instrument is ideal for measuring sets of lenses at the design, prototyping, or production phase. It delivers the most complete lens characterization: on & off-axis MTF, radiometry, and wavefront error at multiple wavelengths. The Kaleo MTF measurement accuracy remains unchanged even at high CRA and FOV.
Key features
- Compatible with large FOV (up to +/- 90°) and CRA (up to 50°) lenses
- Single shot MTF and WFE measurements
- On & off axis infinite to finite configuration
