This study examines the processing and performance of an f-theta lens, one of the main components used in laser printer and laser scanning systems. To design an f-theta lens, the optical path of the components of the laser scanning unit f-theta lens, cylinder lens, and collimator lens must be identified. The goal after machining the master f-theta lens is to understand the optical properties, root mean square, and peak to valley.

문제 정의

This study confirmed the optical performance of a master f-theta lens for the significant surface through precision high-speed processing and ultra-precision processing of a Laser Scanning Unit 600 dpi master f-theta lens. We believe that the study’s data will enable significant performance improvement and mass production of f-theta lens optics in the future.

제안 방법

A preliminary study of the optical system simulation was conducted with Code-V, an optical design software, to simulate whether the beam from the laser diode would actually pass through each lens and emerge beam-sized on the imagery surface. After determining the f-theta scan lens part where the beams pass through at each location, we were able to identify problems in certain areas of the f-theta scan lens.

Through these simulation processes, we calculated the values of K is 467.
⁽⁴⁾ A number of other researchers are conducting additional studies to improve the performance and characteristics of the f-theta scan lens^(5-9). In this study, the processing and performance of a masterf-theta scan lens were evaluated as a prior stage of injection process for the mass production of f-theta scan lenses.
In this study, we used a master f-theta lens featuring one free curve and a aspherical surface. Table 3 presents the specifications of this f-theta lens.
The measurement criteria were based on the values that satisfy the root mean square of 0.06µm and the peak to valley of 0.3 µm or less; in other words, the measurement criteria for aspherical lenses.

대상 데이터

Laser scanning systems in laser compositors and printers serve to convert digital data into light-based information as the computer's digital signal is transmitted to the Laser Scanning Unit. The LSU core components consist of the f-theta scan lens, polygon mirror, cylinder lens, collimator lens, laser diode, laser-controlled circuit board, and case, among others. The most important core technology in LSU transmits light dots from laser diodes to the drums through the correct light source.
Table 1 presents basic specifications for LSU design. The LSU optical system consists of parts such as the f-theta scan lens, cylinder lens, collimator lens, polygon mirror, and laser diode.

이론/모형

5. For the secondary processing, we used the DTM(Diamond Turning Machine: Toshiba, UNC-100F), an ultra-precision processing tool. Moreover, we used special bites for master f-theta lens processing to perform finished cutting machining (as Fig.
The root mean square and peak to valley of the machined master f-theta lens were measured with UA3P (UA3P: Panasonic 3D profilometer), an ultra-precision measuring tool. The measurement criteria were based on the values that satisfy the root mean square of 0.

(3) This study effectively confirmed that the double refraction shape of the master f-theta lens can be improved via heat-based calibration.
