Laser light and laser, we often hear these two types of light in our daily lives. They have a wide range of applications in many fields, such as healthcare, scientific research, industry, entertainment, etc. However, despite their names sounding similar, there are some important differences between them. Firstly, let's take a look at laser light. Laser is a transliteration of "laser" in English. Laser light is a very intense type of light that is emitted by a light source, usually a laser. The wave of laser light
Optical coating refers to a processing method of coating special film materials layer by layer on the surface to optimize and improve optical or optoelectronic properties. It is usually used in optical components to enhance the reflectivity and transmittance of light by changing the properties and structure of the material, thereby promoting the way and shape of light transmission. The main feature of optical coating is that it can change the energy distribution and orientation of reflected light on the surface, improve reflectivity and transmittance, and reduce surface geometric structures or surface gaps
Fluorescent PCR filter is a novel molecular technology that has been widely applied in many biological fields, especially in gene expression analysis, biomarker identification, and genome research, which are of great significance. The fluorescence PCR filter system can effectively reduce the sample size for detection, greatly improve detection efficiency, and significantly enhance the sensitivity and specificity of PCR detection. Fluorescent PCR filters are generally composed of an opaque filter
Filters can be divided into two types: absorption type and interference type. Absorption filters are colored glass that can absorb specific wavelengths of light. The transmittance of absorption type filters is related to the thickness of the glass substrate. The wavelength and bandwidth of absorption filters are not sensitive to the incident angle of the light source, but as the incident angle changes, the thickness of the glass substrate also increases and the transmittance decreases. Interference filter is based on the principle of light interference. If the optical path length of the reflected light from two interfaces
Recently, some customers have inquired about the conversion of OD values after the stacking of filters. Today, we will explain in detail: Firstly, there are two types of filters: 1. The finished product made by using chemical components through photo controlled high-temperature evaporation coating or magnetron sputtering coating is called a dielectric filter (also known as an interference filter), which belongs to the reflective type of filter. 2. Colored glass filters utilize substances (usually heavy metals) doped in glass to specifically absorb specific wavelengths
Some related knowledge about CY5 fluorescent dye. The full English name of CY5 is Cyanine 5, which is a blue pigment fluorescent dye that emits far red fluorescence. It can be linked to genes or proteins through its reaction. Divided into regular cy5 and sulfonated cy5 (Sulfo-cy5). And Cy5 (Suifo-Cyanine5) is a reactive dye used to label peptides, proteins, and oligonucleotides
Infrared optical materials refer to a type of material used in guidance technology and infrared imaging to manufacture filters, lenses, prisms, window panels, fairings, etc. These materials have physical and chemical properties that meet the requirements, namely good infrared transparency and wide projection band. Generally speaking, the transmittance and transmission of infrared optical materials are closely related to the internal structure of the material, especially the chemical bonds and energy level structure. For example, for crystalline materials, the shortwave absorption limit mainly depends on
With the continuous promotion of coating technology, the application fields of optical coating technology are also constantly expanding. The vast majority of optical coating materials used in different fields are rare metals with very small reserves. These rare metals and rare earths are used in small quantities in the industrial field, but they are indispensable and are known as' industrial vitamins'.
