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 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
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
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
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
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

1、 Narrowband filters in optical thin films have a wide range of applications in optical communication systems. They have the advantages of narrow passband, low insertion loss, and good temperature stability. Narrowband filters are commonly used for orthogonal incidence and are typically directly solidified for collimators. However, with the development of science and technology, narrowband filters with oblique incidence are often needed. When light is obliquely incident, the polarization dependent loss of the narrowband filter increases, and the peak and bandwidth of the narrowband filter will shift towards short wave
