There may be special cases in which lenses within these bounds may not be suitable for testing, and there are certainly cases in which lenses outside of these bounds may be tested. However, it is generally true that lenses that fall within the bounds described above are usually good candidates for testing with this instrument. These parameters are seldom independent, making it difficult to place rigid bounds on the space of the lenses that may be tested on LensCheck instruments. Other characteristics that factor into the determination include spatial frequency of interest, chromatic performance of the lens, and departure from telecentricity at off-axis angles. Other relays available for higher spatial frequencies.) Up to 120 lp/mm (assumes standard objective relay lens. Up to 500 lp/mm(assumes standard objective relay lens. ≤1 00mm (with appropriate image analyzer objective lens)į/20 to f/1 (with appropriate image analyzer objective) The suitability of fast, non-telecentric lenses at off-axis field angles is determined by whether the image cone falls within the acceptance cone of the image analyzer objective.
