Filters are generally called filters in photography and astronomical observations, abbreviated as UHC filters. UHC filters are the abbreviation for Ultra High Contrast Filters in English and belong to the broadband filters in the astronomical filter series. UHC selectively blocks certain harmful wavelengths of light, especially artificial light (including mercury and sodium) and natural sky glow, allowing useful light emitted by nebulae to pass through efficiently. This filter
Laser protective lenses, also known as laser window lenses, laser window lenses, etc., are mainly used in laser equipment and can be divided into YAG fiber laser protective lenses and CO2 laser protective lenses (zinc selenide protective lenses). Ruicheng Optoelectronics exclusively launches YAG fiber laser protective lenses that can withstand 21000W laser power and zinc selenide protective lenses that have comparable performance to imported CO2 laser protective lenses. The importance of laser protective lenses in laser equipment: Currently,
A semi transparent and semi reflective mirror, also known as a beam splitter, beam splitter, or semi reflective lens. It is an optical component that is coated with a semi reflective film on optical glass to change the ratio of transmission and reflection of the incident light beam. Coating can increase transparency, increase light intensity, and also increase reflection, reducing light intensity. And semi reflective and semi transparent means that this membrane
Solar simulation technology has been widely applied. In solar photovoltaic science and engineering, aerospace technology space environment simulation, and other solar simulators, the solar simulator filter, as a key optical component, will also develop rapidly. At present, foreign companies mainly produce solar simulators suitable for solar cell testing, such as solar lamps, Xingang, and Technology. The single piece price of its filter is around $1000, which is relatively expensive. Domestic research on solar simulators
Focusing mirror is an optical component that can compress diverging laser beams in terms of angular direction. Due to the large emission surface of optical fibers, they are a diffuse beam of light rather than a collimated or focused spot. Fiber laser focusing mirror can effectively converge the beam at the end of the fiber and control the output beam in a very small area. Depending on the requirements of different applications, two or more focusing lenses can be used, and this type of optical component is called a composite focusing lens. Sometimes non focusing lenses are also used
The concept of a lens: A lens is an optical component made of transparent materials based on the principle of light refraction, with a non planar surface. With the development of advanced equipment manufacturing industry in China, lenses are widely used in various fields such as laser equipment, optical instruments, security equipment, vehicle mounted equipment, digital instruments, etc., and the demand is increasing. Classification of lenses: They can be broadly divided into convex lenses and concave lenses, with thick edge lenses referred to as concave lenses and lenses with thick middle edges referred to as convex lenses. convex
With the rapid development of artificial intelligence products in China, many intelligent products require the use of infrared filters for infrared sensing. It can be said that infrared filters are indispensable optical components in intelligent products. Many customers who are new to infrared filters consult our company about the use of this material. Because they have just come into contact with it, many aspects of their knowledge are unclear. As a manufacturer of infrared filters, we will tell you some questions about this product. 1
With the rapid development of China's economy, the pollution problems of domestic and industrial sewage have gradually worsened. According to the testing of functional departments such as environmental monitoring in China, when the content of organic pollutants in water bodies increases beyond the water's own cleaning capacity, it will lead to the aggravation of organic pollution in water bodies. There are many commonly used methods for detecting water pollution using optical principles, such as colorimeters, etc. This article focuses on introducing one of the more advanced methods in optical detection
Enabling the transmission of light of allowed wavelengths and the cutoff of light of other wavelengths plays a role in suppressing optical noise and enhancing optical signals, thereby providing good preprocessing for image recognition, reducing recognition workload, improving recognition accuracy and efficiency, and enhancing recognition capability. Machine vision filters have a series of characteristics such as small size, good imaging quality, and long lifespan. They are an indispensable and important component of machine vision systems. According to usage needs, some machine vision filters have loops, while others are bare chips
