Optical crystals are mainly used to make windows, lenses, and prisms in the ultraviolet and infrared regions. According to their crystal structure, they can be divided into single crystals and polycrystals. Due to their high integrity, high transmittance, and low input loss, the commonly used optical crystals are mainly single crystals. Nonlinear optical crystal is a type of crystal that exhibits two or more nonlinear optical effects under the action of a strong laser electric field. Nonlinear optical crystal uses a frequency doubling ("frequency conversion") crystal to convert the wavelength of the laser, thereby expanding the tunable range of the laser
As the temperature increases, the radiation peak shifts to the left along the short wave direction, satisfying Wien's displacement theorem. The peak wavelength is inversely proportional to the absolute temperature T. This formula tells us why high-temperature thermometers work in short waves, while low-temperature thermometers work in long waves. When the temperature of an object is above absolute zero, due to the presence of internal thermal motion, electromagnetic waves will continue to radiate towards the surroundings, including infrared light ranging from 0.75 μ m to 100 μ m. His biggest characteristic is that he is given
A dual bandpass filter refers to a single filter that has two bandpass filters. Only one filter is used to capture two specific bands, allowing for the selection of two or more bands to pass through. The dual bandpass filter has high peak transmittance and deep cutoff, effectively suppressing halo and temperature drift, and expanding the application of the filter. Usually used in fields such as security monitoring, machine vision inspection, and intelligent transportation, especially in drone monitoring, dual band filters have significant advantages

The main optical components of a telescope are the objective lens, eyepiece, and prism. Coatings can reduce light loss and reflection caused by reflection, and improve the transmission rate and contrast of light. A limiting factor for binoculars that reflect light. When light hits ordinary glass, 4% of the light is reflected from the glass surface (the glass itself absorbs some of the light because it passes through). Telescopes have an average of 10-16 glass surfaces, and their light loss may be 50% or more of the light initially incident on the objective lens,
Metal mirrors and metal dielectric mirrors are two different types of mirror filters with different film layer combinations. Let's explain them separately below. What are the advantages of metal mirrors: 1. The high reflection band of metal mirrors is so wide that it can cover almost all optical frequency ranges. However, it should be noted that each type of metal reflector with different thin film types has its own best reflection band. 2. The adhesion ability between the metal film of different metal mirrors and the filter material varies. For example,
In the 1950s, scientists discovered that sunlight with a wavelength less than 285 nm was almost completely absorbed by the ozone layer as it penetrated the atmosphere to sea level. This made it almost impossible to detect sunlight in this wavelength range from sea level to an altitude of 20 kilometers. Therefore, this wavelength range is called the sun blind ultraviolet band. By utilizing the characteristics of ozone in the Earth's atmosphere, solar blind filters have strong absorption of natural light in the 200-280nm wavelength range
Laser welding machines belong to the fourth category of laser equipment. Direct exposure to strong laser radiation can cause serious harm to human skin and even blindness. Therefore, debugging personnel must have knowledge of laser safety protection and wear specialized laser protective glasses with corresponding laser wavelengths. Today, Ruicheng Optoelectronics will explain how to maintain and care for laser welding machine reflectors. Note: The adjustment of the laser must be carried out by personnel who have received specialized training, otherwise other components on the optical path may be affected
Optical lenses are usually spherical optical components made of glass or plastic. The lenses produced by Ruicheng Optoelectronics are mainly composed of convex lenses, concave lenses, plano convex mirrors, plano concave mirrors, etc. Optical lenses are implemented in optical systems using the principle of light refraction, including light focusing, light dispersion, and optical imaging; Optical lenses are designed to consist of multiple lenses, which can optimize color correction and correct spherical aberration. This optical lens can be widely used in various safety, automotive, digital cameras, lasers, and optical applications
Filter is widely used in fluorescence microscopes, so many filter designs are determined according to the requirements of microscope manufacturers. Users can place orders based on the model of the sample in use and choose the same or similar filter model from the standard models. Fluorescence filters are widely used in high-precision precision optical equipment, laser processing equipment, measuring instruments, as well as medical beauty, photography equipment, machine vision and other fields. There is no standard size for filters. However, compared to
