Enzyme-linked immunosorbent assay (ELISA) can be divided into two types according to the different filtering methods: filters based ELISA and grating based ELISA. Enzyme-linked immunosorbent
Optical Filters refers to the process of coating one or more layers of dielectric or metal films on a substrate of an optical element to
Filters products are mainly classified by spectral band, spectral characteristics, film material, application characteristics, and other methods. Spectral bands: UV filter, visible filter, infrared filter;
The characteristics of reflectors: 1. Suitable for convenience stores, large supermarkets, road turns, factories, and any right angles in parking lots. 2. Not easily worn
Spherical lenses are divided into convex and concave lenses Convex lens A convex lens is a lens with a thicker center and thinner edges. Convex
A prisms is a polyhedron made of transparent materials such as glass, crystal, etc. It is widely used in optical instrument. Prisms can be divided
Concave lenses have a wide range of applications in optical lenses. A concave lens, also known as a negative spherical lens, has a thin center
Due to the fact that achromatic lenses focus colors at the same point, they allow users to fully focus the image. Compared to uncorrected singlet
Basic concepts and parameters of optical filters 1. Filter differentiation by spectral band: Filters are divided into ultraviolet filters, visible filters, near-infrared filters, infrared filters,
optical coating are ubiquitous in our daily lives, from precision and optical equipment, display devices to optical thin film applications in daily life; For example,
