Enzyme linked immunosorbent assay (ELISA) is a specialized instrument used for reading and analyzing the results of enzyme-linked immunosorbent assay (ELISA). ELISA is performed by coupling enzyme catalyzed chromogenic substrates to antigens or antibodies. The reaction results are displayed in color. The concentration of antibodies or antigens in the sample can be determined by the depth of the colorimetric reaction, i.e. the absorbance value. With the development of detection methods, desktop enzyme-linked immunosorbent assay (ELISA) analyzers with multiple detection modes are called multifunctional ELISA analyzers, which can
The CCD filter commonly referred to as "optical low-pass filter" is widely used in various microscopes, such as fluorescence microscopy, laser scanning confocal fluorescence microscopy, confocal microscopy, and internal reflection fluorescence microscopy. In this article, Ruicheng Optoelectronics will introduce two important functions of CCD filters: filtering out infrared rays and adjusting incoming light. Filter out infrared rays: Color CCD can sense infrared rays precisely because it can sense them
At present, coated filters have been widely used in optical instruments, optical communication, optical remote sensing and other fields, becoming an indispensable component of the optical industry. With the development of the first optical industry, the requirements for thin film filters are also increasing. In addition to high precision and reliability, some special functional filters have also emerged. One new development direction is multi-channel bandpass filters, abbreviated as MPF in English. The so-called multi-channel bandpass filter, as the name suggests, refers to a filter that is compatible with
The difference between grating spectrophotometry and prism spectrophotometry for the same light source is as follows: 1. The resulting spectral patterns are different: prism spectrophotometry produces only one set of spectra, while grating spectrophotometry produces multiple sets of spectra. 2. The principle of use is different: Spectral gratings are based on diffraction principles. A spectral grating is based on light of different wavelengths and colors. After passing through the grating, the distribution of bright lines in the diffraction pattern is different. Prisms are composed of the principle of refraction, and prism spectrophotometry involves the separation of light of different colors
The difference in properties: 1. Optical coating refers to the process of depositing metal or dielectric films on the surface of optical materials. The purpose of coating the surface of optical materials is to reduce or increase reflection, beam separation, color separation, filtering, polarization, etc. The commonly used coating methods include physical coating and chemical coating. 2. Vacuum coating is a method of heating metal or non-metal materials under high vacuum conditions, causing them to evaporate and condense on the surface of the plated part, forming a thin film. For mutants, vampires, chromium chloride coatings, etc
A spectroscope is an optical component that divides light into two parts. Contrary to a beam splitter, a beam splitter allows a portion of light to pass through a filter and reflect other light. In laser and lighting systems, a beam splitter is a common optical component. At present, it is mainly used in laser applications where the light needs to be separated in a ratio of 50:50. In addition, the application scope of spectrometers also includes fluorescence applications, optical interferometry, life science or semiconductor instruments, microscopic imaging
Overview of Long Wave Pass Filter: A long wave pass filter refers to an optical component that allows a certain range of long wave light to pass through or be highly transparent within a specific wavelength range, while cutting off the short wave band below the cutoff point. Its function is to isolate a certain spectral band, and it is a type of cut-off filter. Ruicheng Optoelectronics stipulates that the position point of the long wave pass filter should be identified by the wavelength point with a transmittance of 50%, and the LPF code should be used to represent the long wave pass filter
The definition of short wave pass filter: Short wave pass filter is a cut-off filter in interference filters. Cut off filters are divided into long wave pass filter and short wave pass filter, which require a certain wavelength range of light beam to be transmitted and the light beam deviating from this wavelength to be cut off. Usually, we refer to the filter that reflects (cuts off) the short wave region and transmits the long wave region as a long wave pass filter. On the contrary, the short wave direction is transmitted, while the long wave direction is cut off, which serves to isolate the long wave
The application of optical coated filters has become increasingly widespread, and we are about to enter the fully commercial 5G era. For example, holographic projection technology also relies on the important optical component of filters. From optical equipment, display equipment to the use of optical thin films in daily life, without optical thin film skills as the foundation for development, modern optoelectronic, communication or laser skills would not be able to be developed. This also highlights the primary importance of research on optical thin film skills. Optical coating refers to
