The world’s top manufacturers Edmund Optics and Schott dominate the high-end market, and Chinese manufacturers are accelerating their rise. New materials and intelligent production are driving higher precision breakthroughs, enabling innovations in spectral analysis, laser technology and communications.
Beam splitters are an important optical component that is widely used in spectral analysis, laser technology, optical instruments and other fields. It can separate incident light according to wavelength, thereby realizing the decomposition and measurement of light. With the continuous development of optical technology, the demand for beam splitters is increasing, and the technical level and product quality of manufacturers directly affect their application effects. This article will explore the manufacturers of beam splitters in depth, analyze their technical characteristics, production processes and market applications.
1. Basic principles and classification of beam splitters
The working principle of beam splitters is based on the refraction and dispersion effects of light. When a beam of white light passes through a prism, light of different wavelengths is deflected to varying degrees due to different refractive indices, thereby forming a spectrum at the output end. According to the shape and material of the prism, the beam splitter can be divided into the following types:
1. Equilateral prism: The most common beam splitter, usually made of glass or quartz, has a high dispersion ability.
2. Abbe prism: It consists of two prisms and can achieve wider spectral separation.
3. Littrow prism: It achieves high-precision spectral separation by combining reflection and refraction.
2. Technical characteristics of beam splitter manufacturers
The production of beam splitter involves precision optical processing technology, and manufacturers need to have the following technical capabilities:
1. Material selection: The material of the beam splitter directly affects its optical performance. Commonly used materials include optical glass, quartz, calcium fluoride, etc. Manufacturers need to select suitable materials according to customer needs and ensure the uniformity and optical purity of the materials.
2. Precision processing: The processing accuracy of the beam splitter is extremely high, especially the angle and surface finish of the prism. Manufacturers usually use high-precision CNC machine tools and polishing equipment to ensure that the geometry and optical performance of the prism meet the design requirements.
3. Coating technology: In order to improve the transmittance and anti-reflection performance of the beam splitter prism, manufacturers usually coat the surface of the prism with multiple layers of optical films. The quality of the coating technology directly affects the optical performance and service life of the prism.
4. Detection and calibration: In the production process of the beam splitter prism, detection and calibration are essential links. Manufacturers need to be equipped with high-precision spectrometers, interferometers and other testing equipment to ensure that the optical performance of each prism meets the standards.
3. Application fields of beam splitters
Beam splitters are widely used in many fields, mainly including:
1. Spectral analysis: The beam splitter prism is the core component of the spectrometer, which can decompose complex optical signals into spectra of different wavelengths and is widely used in chemistry, biology, environmental monitoring and other fields.
2. Laser technology: In the laser system, the beam splitter prism is used to separate laser beams of different wavelengths to achieve the output and control of multi-wavelength lasers.
3. Optical instruments: Spectroscopic prisms are widely used in optical instruments such as microscopes, telescopes, and projectors for light decomposition and imaging.
4. Communication technology: In optical fiber communication, spectroscopic prisms are used to separate optical signals of different wavelengths to achieve multi-channel communication.
