From the enzyme-linked immunosorbent assay, it can be seen that the enzyme-linked immunosorbent assay (ELISA) reader should use colorimetric method to analyze the antigen or antibody content. Speaking of which, an enzyme-linked immunosorbent assay (ELISA) reader is a disguised photoelectric colorimeter or spectrophotometer, and its working principle and main structure are basically similar to those of a photoelectric colorimeter. The light emitted by the light source lamp passes through a filter or monochromatic device and becomes a monochromatic beam. The monochromatic beam passes through the sample in the plastic microplate, is absorbed by the sample, and then reaches the photodetector. The detector will project light onto it
The 940nm narrowband filter is an optical component formed by a special coating process on the surface of various glass materials. It can select any desired wavelength from the incident light, and its half peak is generally between 5 and 50 nanometers. It can also replace expensive spectral devices such as gratings, widely used for various spectral measurements and generation. Chemical analysis instruments, optical experiments, and industrial fields. Our company's 940nm narrowband filter technology parameters: Material: Float glass or quartz glass
The first channel long wave infrared ultra narrowband filter of the atmospheric detection infrared spectrometer is specifically designed to detect the concentration of CO2 gas in the atmosphere. Therefore, the optical performance of the filter should be designed based on the characteristic absorption peak of CO2 gas in the atmosphere. The main technical specifications of the first channel filter in the NOAA system atmospheric infrared spectrometer in the United States are: center wavelength of 14.95um, bandwidth of 0.067um
In order to achieve high transparency and isolate harmful light, optical coating refers to light that does not meet our optical specifications. Therefore, a thin film is deposited on the surface of the substrate, and the thickness of the single-layer film is generally tens to thousands of angstroms. Optical thin films include chemical coating and physical coating. Currently, physical evaporation is the main method, which converts the thin film material from a solid state to a gaseous or ionic state, travels through space from the evaporation source, reaches the glass surface, and the material arrives
The definition of infrared filter: Infrared filter is an optical grade material that absorbs or reflects visible light and transmits infrared light. Definition of infrared cut-off filter: An infrared cut-off filter is an optical material that transmits visible light but not infrared light. From the definitions of the two, we can see that infrared filters and infrared cut-off filters are two types of filters with completely opposite optical properties. Nowadays, many people also refer to infrared cut-off filters as infrared filters
The solar simulator is an instrument used to test the evaluation indicators of solar cells, such as short-circuit current Isc, open circuit voltage Voc, and fill factor ff.

Most friends believe that polarizers can only be used in cameras. In fact, polarizers used in photography lenses are very common, but they are also very ordinary because polarizers with precise optical indices are expensive. Of course, if you need to customize an ultra precision polarizer, you can contact our customer service. Today, Ruicheng Optoelectronics will take you to learn about polarizers and the application of polarizer principles in machine vision systems. Many machine vision systems detect the surface of objects and objects

UV filter refers to a filter that does not allow ultraviolet light to pass through, and some people also call it a defogging filter. This is because ultraviolet light is in a warm state in the air, making it invisible to the naked eye during sunny photography, resulting in blurry photos. UV filter can block this harmful ultraviolet radiation. Another use of UV filters is to protect the lens from damage. Available designs for UV filters - Open Design - Open Design Package
Fluorescent filters, also known as fluorescent filters, are widely used in various fields. Its main function is to separate and select the excitation and emission spectra of substances. Fluorescent filters typically use a transparent glass substrate and are coated on both surfaces. The thickness of the anti reflection film will be selected as an integer multiple of half the wavelength, at which point the reflection superposition will be enhanced. The anti reflection thickness is a multiple of a quarter wavelength, and the superposition is enhanced at this time. Fluorescent filters include various types of fluorescent filters, typically
