F-theta lens中文
WebThis integrates an Nd:YAG laser with an xy galvanometer scanner and F-theta scan lens, plus all the necessary control electronics. The actual production system uses two lasers to independently mark on two sides of the device simultaneously. A fast-focusing module is used in the scanner that marks the surface having two different levels. 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.
