This invention relates to a method for controlling the laser line length in microscopic visual inspection based on parametric calculation, belonging to the field of optical microscopic inspection technology, and includes: inputting the target laser line length L. lim The process involves: parameter calculation; adjusting the position or parameters of the cylindrical lens, convex lens, and objective lens to match the calculation results; optical path transmission: the light source emits a collimated laser, which passes sequentially through the cylindrical lens (focusing in the Y direction), the convex lens (adjusting the divergence angle in the X direction), and the objective lens (focusing on the sample surface); real-time detection: a CMOS sensor detects the actual generated laser line length and spot shape; error judgment: determining whether the actual line length meets the target line length error range (<2%): if yes, the final parameter combination and optical path configuration are output, and the process ends; if not, feedback is sent to the parameter calculation module for dynamic fine-tuning of parameters and readjustment of optical components. This invention can improve the accuracy of laser line length in scenarios such as semiconductor defect detection and biological microscopy imaging.

This invention provides a method for inspecting optical films, enabling high-precision and efficient inspection and determining the location information of defects in the thickness direction of the optical film. The invention includes a macroscopic inspection step using a first imaging mechanism and a microscopic inspection step using a second imaging mechanism. In the microscopic inspection step, based on the defect location information determined in the macroscopic inspection step, the position of the imaging field of the second imaging mechanism is controlled in a manner capable of capturing images of the defect. The focal position of the second imaging mechanism is moved to multiple locations in the thickness direction of the optical film, and images are captured at each location, thereby generating multiple captured images. An evaluation object region relative to the defect and its vicinity is determined in the composite image obtained by combining the multiple captured images. Based on the brightness values ​​within the same pixel region as the evaluation object region, a focused image is determined among the multiple captured images, and detailed information about the defect is obtained based on the focused image.
