Infrared filters, as a specially designed optical device, allow infrared light within a specific wavelength range to pass through while blocking other wavelengths of light, especially visible light and ultraviolet light. The working principle of this filter is based on the selective absorption and transmission…
A narrowband filter is an optical filter designed with a narrow bandwidth. It is a type of bandpass filter that can selectively transmit light in a very narrow specific wavelength range while blocking light of other wavelengths. Its core feature is that the bandwidth is…
In the field of optics, optical filters are endowed with unique optical properties through their special construction materials and film materials, and different optical filters have different actual performance. Today we will talk about a classification of cut-off filters, long-wave pass filters. Among various types…
A short-pass filter, also called a low-pass filter in some cases, is an optical device that allows shorter wavelengths of light to pass through while blocking longer wavelengths. This type of filter is essential in a variety of scientific, industrial, and technological applications that require…
In an era dominated by visual communication, the unassuming infrared cutoff (IRC) filter has emerged as a silent enabler of our digital vision. Embedded within smartphone cameras and surveillance systems alike, this optical component performs a delicate balancing act between light management and spectral purity,…
Color filter is a key material in modern display technology, especially in the field of liquid crystal display (LCD). It filters white light into three basic pigment dot matrices of red, green and blue through a specific process, thereby realizing color display. This article will…
Polarizer, also known as polarizing filter, is an optical element that controls the polarization state of light waves. By filtering out light with a specific polarization direction or generating a beam with specific polarization characteristics, polarizers play an important role in optical imaging, photography, polarization…
Photorejuvenation is a popular non-invasive beauty method that relies on advanced optical technology to improve skin quality. It acts on the skin with photons of specific wavelengths, reduces pigmentation and stimulates collagen production. The optical screening process requires the use of filters. The core of…
