WebTo meet the full optical potential of the infinity system, the objective parfocal distance must be matched to the tube lens focal length. Thus, for a 200-millimeter focal length, the optimum parfocal distance is 60 millimeters, exceeding the older standardized length by 15 millimeters. Interactive Tutorial - Tube Lens Focal Length WebIR corrected When lenses are designed, one of the important parameters is the spectrum for which the lenses are to be used. Most lenses on the market are “corrected” (read : “designed”) for the visible range of the light, the part that humans can see. These are wavelengths between about 420nm and 720nm, deep violett to deep red colors.
