  What is a spherical lens? What is an aspheric cylindrical lens ? What is the difference between spherical and aspheric lenses ? Why are aspheric lenses recommended? Let's talk about the difference between the two.   The spherical lenses have a spherical surface, and the radius of curvature of the entire lens is the same. On the contrary, the surface of an aspherical lens is more complicated, and the curvature gradually changes from the center to the edge. These design differences can reduce the number of elements in the assembly and result in thinner and lighter lenses.   The surface of the spherical lens looks like a part of a spherical or cylindrical surface.   The curve is the same across the entire surface. If you draw a straight line to follow the curve, it will form a circle. Because the design is simple, the spherical lens design is usually cheaper.   The surface of an aspheric lens must not be part of a sphere or cylinder. The curve of some parts of the lens surface chang

  1. Introduction to double concave lens   A double concave lens  is also called a negative spherical lens. The middle of the lens is thin, the edge is thick, and it is concave, so it is also called a concave lens, which has a divergent effect on light.   The imaging law of the concave lens is: when the object is a real object, it becomes an upright, reduced virtual image, and the image and the object are on the same side of the lens. The concave lens has a divergent effect on the light, so the lens is also called a divergent lens, a negative spherical lens.   2. Features of biconcave lens:   A double concave lens is concave on both sides and has the same radius of curvature. A double concave lens with a negative focal length is usually used for beam collimation, increasing (decreasing) the focal length or enlarging (shrink) the image.   The double concave lens has a negative focal length and is often used in imaging or beam collimation applications. The coated lens is also widely used

  Ecoptik uv dome  lens is composed of two parallel optical surfaces, (A convex surface & A Concave surface). Normally we can control the parallel tolerance <±2μm. A perfect parallel surface, in the imaging, the image does not distort, and in the measurement of light, the light does not distort. Ecoptik Dome, the optical properties are unique, which are produced by the optical technology of optical grinding and polishing.   Ecoptik Dome lens mainly is hemisphere, hyper-hemisphere and customized designing. Whether it is a visible dome, UV dome or IR dome, Ecoptik also known as BRD Optical ) Dome has been confirmed in the international market. Ecoptik dome is found in areas such as defence technology, weather monitoring and optical imaging.   Description Of Ultraviolet (UV) Dome   Ecoptik (also known as BRD Optical) optical dome  lens is composed of two parallel optical surfaces, (A convex surface & A Concave surface).

  The scanning mirror  applications include ultra-high dynamic, low inertia scanning mirrors for laser processing, streak cameras, LIDAR, security, sensing and targeting applications, where the enhanced flexural strength, homogeneity, high resonant frequencies, ultra-low inertia, and optical surface quality are key.   Description Of Scanning Mirror The scanning mirror of ecoptik co., ltd. ( also known as BRD Optical) is light weight rectangular mirror that used for high speed two-axis laser scanning system. The dimensions for each mirror have been calculated accordingly with the laser beam size. The optical mirror has high reflectivity of 99.5% or above. The scanning mirror system  usually mounted on to a galvanometer for scanning purposes. For two axis scan mirror, commonly the Y mirror has a bigger size compared with the X mirror. This is due to the fact that the X mirror is used to scan the Y mirror rather than the object directly.   Description Of Scanning Mirror Specifications Of
