This invention provides a light-transmitting and water-blocking packaging film, comprising a packaging label layer, a front protective film, a back protective film, reinforcing sheets, carbon black areas, and a sealing frame. The packaging label layer, the front protective film, and the back protective film are composited to form a sandwich structure, with several reinforcing sheets disposed between them. Corresponding carbon black areas are provided on the packaging label layer, the front protective film, and the back protective film. The sealing frame is integrally formed on the surface of the back protective film. This invention uses a sandwich structure composite packaging label layer, etc., with circular glass fiber reinforcing sheets in between to improve tensile strength. The gradient carbon black areas at the edges of the three films absorb ultraviolet rays and resist aging. The inner adhesive area of ​​the arc-shaped sealing frame at the edge of the back protective film is sealed and water-blocking, protecting the items.

The invention discloses a preparation method of 193nm photoresist resin. The preparation method comprises the following steps: synthesizing resin to obtain a synthetic resin solution, wherein monomers synthesized during synthesis comprise the following raw materials in molar percentage: 99.9-99.99% of an anti-etching methacrylate monomer and 0.01-0.1% of a methacrylate monomer with epoxy; removing impurities and unreacted monomers in the synthetic resin solution to obtain a No.1 resin solution; removing metal impurities in the first resin solution to obtain a second resin solution; replacing a solvent in the second resin solution with an electronic-grade solvent to obtain a third resin solution; a resin solution containing electronic grade secondary and tertiary amine groups is added into the third resin solution, and the molar weight of an electronic grade secondary amine compound is 95-100% of the molar weight of epoxy groups in the methacrylate monomer with epoxy. The epoxy group monomer introduced in the resin synthesis process is methacrylate, the basic structure, the etching resistance, the light transmission and the like of the resin cannot be influenced, and due to the fact that the tertiary amine group is synthesized on the resin, the tertiary amine group cannot be volatilized during later use.

The present invention belongs to the field of pupil positioning technology. A pupil positioning method, system, medium, product and system based on OCT are proposed to calibrate the scanning area; when the fundus image of the subject is lost due to micro-movement, the current first frame image is collected, and the second frame image is collected after the focus is moved, and the axial distance between the current focus and the pupil is obtained by processing; then the focus is moved to the calibration position, and the third frame image is collected, and the pupil position is obtained after processing, and the horizontal distance and vertical distance to be moved by the current focus are calculated, and the focus is moved to the pupil position in combination with the axial distance between the current focus and the pupil to complete the positioning. The present invention can help the OCT device locate the pupil and regain the fundus image, with low cost and without affecting the light path transmittance.
