An electronic transformer having an electronic device that converts an alternating voltage of a commercial power into a direct current and forms a high-frequency alternating current voltage output through a semiconductor switching device and an electronic component and a high-frequency transformer winding, and is also described in an electronic theory. A crossover inverter circuit. Simply put, it is mainly composed of a high-frequency transformer core (core) and two or more coils, which do not change position from each other, from one or two electrical circuits, through AC power Magnetic induction, converted into AC voltage and current. At the output of the high-frequency transformer, one or more power circuits are supplied with high-frequency alternating current or direct current of different voltage levels.
Cylindrical lenses have at least one surface that is formed like a portion of a cylinder.Cylindrical lenses are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism,stretching a point of light into a line.They are available in either plano-concave or plano-convex configurations. Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens. Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
