Singlets AchromatsF-Theta-Ronar Lenses 532 nmThe following is valid for the overview​tables at the bottom:••The entrance beam diameter (beam-Ø)​refers to the intensity 1/e 2 at Gaussian​illumination. The image spot diameter​(spot-Ø) refers to the intensity 1/e 2 at​Gaussian illumination. It can be​calculated 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]••The mirror distances m1 and m2 are​recommended values••The overall scan angle Ñ refers to the​maximum diagonal scan angle••The scan length can be calculated with​the formula:••The listed F-Theta-Ronar lenses​accomplish the F-Theta-conditionbetter​than 0.1% except for a fewversions.​These lenses which have alarger scan​field due to distortion areindicated with​**.••The effective focal length (EFL), flange​focal length (FFL) and back focallength​(BFL) have been calculated bymeans of​paraxial relations (for raysclose to the​optical axis). In reality,they can slightly​deviate from the datashown in the​following tables by theactual entrance​beam diameters andmirror positions​used.• • The data for the entrance beam​diameter and the mirror positions are​recommended values.
