摘要： The present invention mainly relates to the structure and manufacturing process of a new fθ lens in LSU, which is plastic lens produced through injection molding. Its optical surface is made of multi-sections, and the optical surface of each section, according to the angles formed between the sections and the laser beams ripping-in, are designed with a specified coefficient set. Therefore, this new fθ lens, with high tolerance in assembling and high performance in scanning, avoids the demerit of conventional fθ lens, each optical surface of which has only one coefficient set. According to the curve fall formed at the border of every two optical surfaces, we find out a way to ascertain the best continuing surface profile, which is curve fitting simulation and optical simulation. At last, we produce a mold for the fθ lens with multi-sections optical surface by using super-precise machine process to control the mold processing and use the mold for injection molding, and then manufacture lots of fθ lens with multi-sections optical surface.

摘要： A method for designing an optical device which includes a lens and a microlens array is disclosed. A point spread function (PSF) of the lens including rotationally symmetrical aberration coefficients is formulated, wherein the PSF presents various spherical spot sizes. A virtual phase mask having phase coefficients is provided and the phase coefficients are added to the PSF of the lens, such that the various spherical spot sizes are homogenized. The virtual phase mask is transformed into a polynomial function comprising high and low order aberration coefficients. A surface contour of the lens is determined according to the rotationally symmetrical aberration coefficients and the low order aberration coefficients, and a sag height of each microlens in the microlens array is determined according to the high order aberration coefficients. An optical device using the design method is also disclosed.

摘要： A laser scanning unit mainly includes a semiconductor laser, a collimator, a micro electronic mechanic system (MEMS) oscillatory mirror, and an fθ lens or an f sin θ lens. The MEMS oscillatory mirror is disposed between the collimator and the fθ lens to replace a conventional rotary polygonal mirror for controlling a direction in which laser beams are projected from the oscillatory mirror to the fθ lens. With the MEMS oscillatory mirror, the cylindrical lens may be omitted from the laser scanning unit and noises produced by the polygonal mirror rotating at high speed may be avoided. Moreover, the MEMS oscillatory mirror allows bi-directional scanning to therefore enable increased scanning frequency, simplified structure, and improved scanning efficiency.
