| Zusammenfassung: | FIELD: optics. ^ SUBSTANCE: system has television tube, protective glass, meniscus, three correction-force components with aspheric surfaces, and home video system screen. Meniscus together with protective glass forms a hollow for cooling liquid. Correction-force component is made in form of glass lens. onto at least one surface of lens plastic layer is applied with a spherical contact surface and outer aspheric surface. Plastic layer has optical force. Refraction coefficient of plastic layer is not equal to refraction coefficient of lens glass. ^ EFFECT: higher quality, lower costs. ^ 1 dwg |
