Claims (4)

1. Оптический датчик, содержащий: световой модуль для излучения светового потока и приема светового потока, отраженного от носителя записи, и твердотельную иммерсионную линзу (ТИЛ), расположенную на пути луча между указанным модулем и носителем записи и имеющую плоскую поверхность, обращенную к носителю записи, и несколько эллиптически изогнутых поверхностей с различными радиусами кривизны для обеспечения симметричности по отношению к центральной оси своей поверхности, воспринимающей падающий свет от светового модуля для его фокусирования и создания светового пятна на записывающей поверхности носителя записи.1. An optical sensor comprising: a light module for emitting a light flux and receiving a light flux reflected from the recording medium, and a solid-state immersion lens (TIL) located in the path of the beam between the specified module and the recording medium and having a flat surface facing the recording medium , and several elliptically curved surfaces with different radii of curvature to ensure symmetry with respect to the central axis of its surface, which receives incident light from the light module for its focuses and creating a light spot on the recording surface of the recording medium. 2. Оптический датчик по п. 1, отличающийся тем, что радиус кривизны эллипса, расположенного на большем удалении от центральной оси, превышает радиус кривизны эллипса, расположенного на меньшем удалении от центральной оси. 2. The optical sensor according to claim 1, characterized in that the radius of curvature of the ellipse located at a greater distance from the central axis exceeds the radius of curvature of the ellipse located at a smaller distance from the central axis. 3. Оптический датчик по п. 1, отличающийся тем, что дополнительно содержит рефлектор, установленный на траектории луча между световым модулем и ТИЛ и предназначенный для регулирования угла наклона падающего света. 3. The optical sensor according to claim 1, characterized in that it further comprises a reflector mounted on the path of the beam between the light module and the TIL and designed to control the angle of inclination of the incident light. 4. Оптический датчик по п. 1, отличающийся тем, что дополнительно содержит волоконно-оптический элемент, установленный на пути луча между световым модулем и ТИЛ и предназначенный для передачи светового потока между ними. 4. The optical sensor according to claim 1, characterized in that it further comprises a fiber optic element mounted on the beam path between the light module and the TIL and designed to transmit the light flux between them.
