What is Optical Coating?

Optical coating is the process of plating one (or more) metal (or dielectric) film on the surface of optical parts. The purpose of coating on the surface of optical parts is to achieve to reduce or increase the light reflection, beam splitting, color separation, filtering, polarization and other requirements. Commonly used coating methods are vacuum coating (a kind of physical coating) and chemical coating. With physical or chemical methods on the surface of the material coated with a transparent electrolyte film, or plating a...

What is sapphire glass?

First of all, to be clear, sapphire could not have been called glass. Glass is a silica-based transparent post-fusion solidified body to which various elements have been added in order to meet different requirements, but the main component is silica. Sapphire is a crystal, a single-crystal arrangement of aluminum trioxide. Because sapphire becomes transparent after polishing, it is also called sapphire glass. Sapphire glass...

What is quartz glass?

Quartz glass, made by melting all kinds of pure natural quartz (such as crystals, quartz sand, etc.), is a kind of silica single-component special industrial technology glass. The hardness of this glass can be up to Mohs' seven, with high temperature resistance, low coefficient of expansion, heat shock resistance, chemical stability and good electrical insulation properties, and can transmit ultraviolet and infrared rays. In addition to hydrofluoric acid and hot phosphoric acid, it has good acid resistance to general acids. According to the transparency...

What is K9 glass?

K9 glass is a glass product made of K9 material, which is used in the field of optical coating, etc. K9 material belongs to optical glass, because it is crystal clear, so it has given rise to a lot of factories that process K9 material as the object, and the products they processed are called crystal glass products in the market. The composition of K9 is as follows: SiO2=69.13% B2O3=10.75% BaO=3.0...

How many types of filters can be classified according to their spectral characteristics?

Filters can be classified into six categories based on their spectral characteristics: Bandpass filters, cutoff filters, spectral filters, neutral density filters, reflection filters, and negative filters (trap filters); Band-pass type: light in the selected band passes through, and light outside the passband is cut off. Its optical indicators are mainly center wave (CWL), half bandwidth (FWHM). Divided into narrowband and broadband. ...

Biochemical filters

Biochemical analysis is one of the most frequently used clinical tests, which analyzes blood or other body fluids to determine a variety of biochemical parameters such as aminotransferases, hemoglobin, cholesterol, muscle liver, glucose, etc. Combined with other clinical data, it can help diagnose diseases, evaluate organ function, and determine the baseline for future treatment. Combined with other clinical data, this analysis can help diagnose diseases, evaluate organ function, and determine the baseline for future treatment. Our company has developed a series of biochemistry instruments, enzyme...

How many types of filters are available according to spectral bands?

Filters are categorized by the length of the spectrum (i.e., the region in which the spectrum is located) into: ultraviolet filters, visible filters, near-infrared filters, mid-infrared filters, and far-infrared filters. Spectral wavelength range: UV filters 1-380nm Visible filter 380-780nm Near-infrared filters 780-1500nm Infrared Filter 150...
