It can becalculated by the formula:Spot-Ø = 1.83 x λ x EFL / beam-ØSpot-Ø: image spot diameter [μm]1.83: factor of apodisationλ: wavelength [nm]EFL: focal length [mm]Beam-Ø: entrance beam diameter [mm]••<strong>The</strong> mirror distances m1 <strong>and</strong> m2 arerecommended values••<strong>The</strong> overall scan angle Ñ refers to themaximum diagonal scan angle••<strong>The</strong> scan length can be calculated withthe formula:••<strong>The</strong> listed F-<strong>The</strong>ta-Ronar lensesaccomplish the F-<strong>The</strong>ta-conditionbetterthan 0.1% except for a fewversions.<strong>The</strong>se lenses which have alarger scanfield due to distortion areindicated with**.••<strong>The</strong> effective focal length (EFL), flangefocal length (FFL) <strong>and</strong> back focallength(BFL) have been calculated bymeans ofparaxial relations (for raysclose to theoptical axis).
