The following is valid for the overview tables at the bottom:
The entrance beam diameter (beam-ø) refers to the intensity
1/e² at Gaussian illumination. The image spot diameter (spot-ø)
refers to the intensity 1/e² at Gaussian illumination. It can be
calculated by the formula:
Spot-ø = 1.83 x λ x EFL / beam-ø
Spot-ø: image spot diameter [μm]
1.83: factor of apodisation
λ: 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 Θmax refers to the maximum diagonal
scan angle
The scan length can be calculated with the formula:
2y‘= EFL x Θ x π/180
2y‘: scan length or diagonal [mm]
EFL: focal length [mm]
Θ: overall scan angle [°]
π/180: conversion factor into radians
The listed F-Theta lenses accomplish the F-Theta-condition
better than 0.1% except for a few versions. These lenses which
have a larger scan field due to distortion are indicated with.
