F-theta lens中文

WebF-Theta Lenses. F-Theta Lenses are used in laser optic systems that are designed to focus on a planar image. These provide distortion to make the image height proportional to the focal length and scanning angle theta. These can be filtered by wavelength, lens material, focal length, beam diameter, and more.

WebF-Theta Lens; This lens focuses a laser beam scanned with a scanner, etc. It is used for high speed micro drilling of printed circuit boards, high-speed marking of electronic parts and resin parts, etc. Highly precise telecentric lenses minimize distortion and make a laser beam incident almost perpendicularly to the work piece. It is suitable ... WebA short-focal-length F-Theta lens facilitates short working distances, as well as very compactly-dimensioned systems. Long focal length, on the other hand, allows the processing of large image fields without external axes. SCANLAB offers a diverse variety of F-Theta lenses or flat field objectives (e.g. along with telecentric objectives). http://energy.phys.ncku.edu.tw/optics/book_3/b3_c19.PDF 46不通

WebAperture stop and scan mirror distances. F-theta lenses are designed to focus a laser beam onto a planar image plane. They are often used in a scanning system with two galvanometer mirrors. One mirror is responsible for beam deflection in one direction and the second one for the perpendicular direction. For simulation purposes an aperture stop ... 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.
