Fluid jet polished aspheric elements can be used to fully correct a variety of optical systems
Standard correctors can be made based on the collimator or imaging lens designs. These types of correctors can eliminate 90% of the optical errors that are preventing these optics from achieving diffraction limited performance (design correction)
Correctors can be polished based on wavefront measurements of collimators or imaging lens or afocal telescopes or measurements of the accumulated errors of entire optical systems and reduce all the accumulated errors to get as close to the diffraction limit as possible. design, prescription, alignment, assembly tolerances. Measure your system performance, send dat file, let us see what we can do with a fluid jet polished corrector
Example 1. - A high performance fiber coupled NIR collimator, focal length 60mm
Wavefront distortion is clearly present to a significant level, 100nm!
Now fully corrected by design with a fluid jet polished aspheric corrector, wavefront errors < 4nm
Example 2. - A Triplet
A nice triplet , fully corrected to about +/- 5 degrees (if the elements and the assembly are perfect)
Actual performance with typical high precision manufacturing and assembly
Now fully corrected with a real world performance that is close to diffraction limited over a +/- 10 degree field of view
Example 3. - A well designed 300mm doublet imaging a +/- 4 degree field of view
The line represents the diffraction limit and we can see that it is fully corrected to about 1.2 degrees
Adding a conventional corrector improves the performance but it still not diffraction limited beyond about 1.2 degrees
Adding a fluid jet polished aspheric corrector fully corrects the image with over the full field and beyond. The performance is now diffraction limited over the full field
