WebThe primary advantage of a telecentric lens is that its magnification does not change with respect to depth. Figure 2 shows two different objects at different working distances (WD), imaged both by a fixed focal length … 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. food network chocolate sugar cookies
