WebDec 25, 2024 · They state that the field size of your lens is 140 x 140 mm. This is equivalent to 197 mm on the diagonal, or 98.5 mm on the half-diagonal. If the lens is a true f-theta lens, then the scan angle to give the full field is theta = h / f, where h=98.5 mm, f=230 mm, so theta = 0.42 radians or 24.5 degrees. http://www.asdoptics.com/?trk=public_post-text chemical shell
