Lens is an optical element made of transparent materials (such as glass, crystal, etc.), which will affect the wavefront curvature of light. It is a device that can aggregate or disperse light, and the resulting image has both real and virtual images. Widely used in security, car wear, digital cameras, lasers, optical instruments and other fields.
Various ordinary colorless optical glasses including fused quartz, calcium fluoride, Optical lens manufacturermagnesium fluoride, silicon, germanium, zinc selenide and other materials; And various wave bands of flat convex lens, biconvex lens, flat concave lens, biconvex lens, super hemispherical lens, small ball lens, meniscus lens, cylindrical mirror, rod mirror, glued mirror, etc.
Imaging law of lens and convex lens
1. The lens is represented by the lens symbol (there are two V-shaped marks at both ends of a line segment), the main optical axis is drawn, the optical center and focus are marked, and the characteristics of the image formed by the lens (such as virtual reality, size, positive and negative, etc.) can be obtained according to the intersection of two refracted rays (generally, the light passing through the optical center and the light parallel to the main optical axis) of the three special rays of the lens.
2. During lens imaging, all the light emitted from each point on the object that shines on the lens is Optical lens manufacturer imaged at the same position, blocking a part, which does not affect the imaging of other light emitted to the lens, so the complete image can still be seen, but the brightness of the image on the screen will be dimmed due to the reduction of the light emitted on the image.
3. Convex lens imaging law:
(1) One of the conditions that a convex lens needs to meet to form a real image is（ 2) Conjugate imaging means that the size of object distance and image distance can be interchanged, and the two cases are inverted real images that are enlarged and reduced respectively
4. When looking at the clock beyond the double focal length through the convex lens, Optical lens manufacturer the image of the second hand still rotates clockwise, because it is an inverted real image at this time, and it is still a normal direction when looking backwards, so it still rotates clockwise.
