K9 Bk7 B270 Aspheric Lens High-Quality and Customizable with Coating Option Optical Lens Factory Direct Sale

Product Description

Product Description

A lens is made according to the law of refraction of light. A lens is a refractive mirror, with its refractive surface being two spherical surfaces (a part of a sphere), or one spherical surface and one plane of a transparent body. The images formed by the lens can be real or virtual. Lenses are widely applied in various fields such as security, vehicles, digital cameras, lasers, optical instruments, etc. With the continuous development of the market, lens technology is becoming increasingly widely used.

Optical Applications‌

A lens is a type of lens where the thickness of the central part is much greater than the curvature radii of its two surfaces. Optical glass has high transparency, purity, colorlessness, uniform texture, and good refractive ability, making it the main raw material for lens production. The lens is the most fundamental optical component of the optical system of a microscope. Components such as the objective lens, eyepiece lens, and condenser lens are all composed of single or multiple lenses. Depending on their different shapes, they can be divided into convex lenses (positive lenses) and concave lenses (negative lenses). When a beam of light parallel to the principal axis passes through a convex lens, it converges at a point, which is called the "focus". The plane passing through the focus and perpendicular to the optical axis is called the "focal plane". There are two foci, the one in the object space is called the "object space focus", and the focal plane at this point is called the "object space focal plane"; conversely, the one in the image space is called the "image space focus", and the focal plane at this point is called the "image space focal plane". Light passing through a concave lens forms a virtual image upright, while a convex lens forms a inverted real image. Real images can be displayed on a screen, but virtual images cannot.
