When a laser cutting machine cuts metal materials, a large amount of gas, slag, and splashes are released from the working surface. Maintaining the lens is used to prevent damage to the aggregated lens during the cutting process. Of course, it is not only used for laser cutting machines, but also for laser welding, marking, engraving and other laser equipment, so the market for maintaining lenses is very strong. On the back of strong market demand, there are generally uneven product prices and quality. How many maintenance lenses are available on the market
The so-called narrowband filter is a subdivision of the bandpass filter, and its definition is the same as that of the bandpass filter. This type of filter allows light signals to pass through a specific band, while blocking light signals on both sides outside of this band. The passband of a narrowband filter is relatively narrow, generally less than 5% of the center wavelength value. Parameter description of narrowband filter: The center wavelength of narrowband filter is generally the operating wavelength of the instrument or equipment, which refers to
With the development of optical technology, there is an increasing demand for precision optical coating, such as ultrafast laser optical components and special laser optical components, which have very high requirements for coating. Generally speaking, the price and quality of substrates depend on the material, shape, size, tolerance, and polishing quality. The first step in material selection is usually to determine the material of the substrate, which should ideally have high transmittance for all wavelengths and almost no absorption. If it is not transmissive, low cost can be used
At a certain angle, a dichroic mirror is typically used to split a beam of light into two different directions of spectral light. The commonly used fluorescence microscope is an elongated dichroic mirror, which reflects the excitation light and fluorescence light transmission ratio in the fluorescence principle diagram. The dichroic mirror also uses stage filters for fluorescence microscope illumination equipment and projectors. A multi bandpass filter is a single filter with multiple bandpass filters, which is our company's most distinctive and competitive product. The manufacturing of multi bandpass filters requires high technology and high transparency
In the field of photography or optics, neutral optical filters, also known as ND filters, are filters that can reduce or change all wavelengths or colors of light without altering the color tone. It can be a colorless filter or a gray filter. The purpose of standard photography neutral filters is to allow photographers to flexibly change the aperture, exposure time, and dynamic blur of the target object in different environments and shooting conditions. Principle neutral density filter, optical
In the past, optical filters were mainly used in the field of microscopes. With the rapid development of high-quality manufacturing in China, the application of optical filters has become increasingly widespread. As a result, the workforce is also expanding. Ruicheng Optoelectronics Thermal Column welcomes friends who are willing to work in the optical industry to join our team, with excellent treatment. Classification method of filter: Filter can be divided into TIRF filter, interference filter, and total internal reflection filter according to different usage purposes
The optical beauty device uses laser, strong pulse light, E-light, and infrared light as light sources to achieve beauty effects such as acne removal, freckle removal, red blood streaks removal, skin rejuvenation, hair removal, eyebrow and tattoo removal. Due to the unique spectral characteristics of these light source products, they need to be matched with optical filters to achieve a certain functional effect. At the same time, it can prevent stray light from causing damage to human skin. Ruicheng Optoelectronics produces customized filters for various wavelength bands that meet customer needs for optical beauty instruments
The principle and composition of frequency doubling lenses in laser accessories. Frequency doubling lenses can convert various invisible infrared beams into visible light, effectively detecting, tracking, calibrating, and identifying infrared beams. They are used in various fields such as near-infrared light detection of semiconductor lasers, tracking of infrared light-emitting diode emission light, calibration of YAG and other large laser beams, and detection of fiber optic communication signals. The infrared detection board is made of upconversion luminescent material, which can be powder, ceramic, or glass
After using the laser marking machine for a period of time, there may be problems such as the laser marking machine not being able to mark properly or not emitting light. After careful investigation, we found that there was a problem with the vibrating lens. At this point, we need to remove the vibrating mirror and send it to the manufacturer or designated repair area for maintenance, and then the repair number will be assigned. We still need to install the vibrating mirror. This article mainly focuses on two aspects: removing the vibrating mirror and installing it. The steps to remove the vibrating mirror are as follows: 1. In
For users who have used laser marking machines, I believe everyone knows that many laser marking machines, such as fiber laser marking machines, ultraviolet laser marking machines, CO2 laser marking machines, etc., are equipped with field mirrors
