The F15-300mm zoom system is composed of visible light zoom lens, control circuit board and power supply circuit board. The visible light zoom lens includes CCD, optical lens, diaphragm, potentiometer, micro-dc motor, CAM and other structural parts. 3 Optical lens design 3.1 Zoom lens system is an optical system in which the focal length changes within a certain range and the image plane remains fixed. In general, the relative aperture is constant during zoom.For imaging system, continuous zoom optical system is the best way to solve the problem of large field search and small field resolution. The ratio of the two ultimate focal lengths in the zoom range, namely the ratio of the long focal length to the short focal length, is called magnification ratio, also known as multiplier. In consideration of the secondary spectrum requirements, the plan of the small relative aperture of the long focal length is adopted (that is, the relative aperture also changes during the zoom process). 3.2 The optical system USES a continuous zoom lens with a focal length of 15mm~300mm.

Optical Cylindrical lens Optical Glass Plano Convex Cylindrical Lens A Optical glass Cylinder Lenses is used to condense light in one axis. A positive cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping.
