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
With the continuous promotion of coating technology, the application fields of optical coating technology are also constantly expanding. The vast majority of optical coating materials used in different fields are rare metals with very small reserves. These rare metals and rare earths are used in small quantities in the industrial field, but they are indispensable and are known as' industrial vitamins'. In the application of optical coating materials, coating targets are the core technology. Different optical coating materials are formed by the different rare metals contained in different targets
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
The field lenses produced by Ruicheng Optoelectronics commonly include 70 * 70, 110 * 110, 150 * 150, 200 * 200, 220 * 220, 300 * 300, 500 * 500, etc
The IRCUT dual filter switcher allows ordinary day and night cameras to operate with different filters at night and during the day, effectively solving the problem of dual peak single filter day and night that cannot be balanced.
Since light is an electromagnetic wave, its characteristics such as interference, diffraction, polarization, etc. should be manifested during propagation.
