`LensCheck™ VIS Lens Testing System
`
`Portable and Precise for Visible Infrared Lens Measurements
`
`A cost-effective solution to your production and prototype lens qualification needs. Optikos, the leader in image
`quality test equipment, is pleased to offer this compact, efficient, easy-to-use quality control tool. LensCheck,
`with patented VideoMTF® image analysis software, features real-time MTF testing and analysis that allow
`manufacturers to qualify incoming products quickly and reliably, thereby minimizing the risks of sub-standard
`complete assemblies.
`
`Applicable Lenses for Testing:
`
`The suitability of the LensCheck VIS for testing a visible wavelength lens depends primarily on:
`
` Entrance pupil diameter
`Focal length,
`f-number of the lens, and
`
`
`
`
`
`
`
`Image format size
`
`
`
`up to 50 mm
`3-200 3-200mm (with appropriate image analyzer objective lens)
`f/20 – 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.
`up to 25 mm image diagonal
`
`Other characteristics that factor into the determination are:
`
`
`
`
`
`
`
`spatial frequency of interest
`chromatic performance of the lens
`departure from telecentricity at off-axis angles
`
`These parameters are seldom independent, making it difficult to place rigid bounds on the space of lenses that
`may be tested on the LensCheck VIS. Nonetheless, it is generally true to say that lenses that fall within the
`bounds given below are usually good candidates for testing with this instrument. There may be some special
`case 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. When in doubt, consult an Optikos engineer for advice.
`
`Applicable Measurements:
`
`
`
`
`
`
`
`
`
`
`
` MTF – on/off axis
`EFL and f-number
`
`Back focal length
`Astigmatism
`Field Curvature
`Distortion
`Transmission (optional)
`Relative illumination (optional)
`Line of Sight (optional)
`Veiling glare (with optional instrument)
