From September 11 to 13, 2024, the 25th International Optoelectronics Exposition, focusing on China’s advanced optoelectronic technologies, was officially held at the Shenzhen Bao’an International Convention and Exhibition Center. Jiite, together with Anshan and Nanjing branches, gathered here (booths 7B31 in Hall 7 and 1A73…
In the process of making optical filters, for coated filters, the degree of cleaning of the substrate determines the quality of the coated products. Ensuring the high cleanliness of optical components before coating is the most important step in the filter manufacturing process. The substrate…
Short-wave pass filter, also called short-wave filter, low-pass filter, long-wave cut-off filter, is a type of cut-off filter. It is an optical filter that only allows short-wavelength light to pass through and blocks long-wavelength light, that is, it is mainly used to block the interference…
As an important optical component, optical filters are widely used in scientific research, medical treatment, industry and other fields. In the production process of filters, there is a significant difference in cost between customized filters and standard filters. This article will explore the reasons for…
Temperature drift refers to the phenomenon that the performance, parameters or output results of a physical device or system are offset or changed due to changes in ambient temperature. This drift is usually an unavoidable physical effect that affects measurement accuracy, system stability and equipment…
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…
Infrared temperature measurement filters are optical filters specially designed for infrared bands and are commonly used in non-contact temperature measurement equipment. They can selectively transmit infrared radiation and filter out interference light from other bands, thereby achieving high-precision temperature detection. This article will introduce in…
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…
Optical components are an indispensable part of optical systems, used to manipulate, adjust or detect the behavior of light. With the continuous development of optical technology, the functions and application range of these components are becoming increasingly rich. From basic optical functions to complex adaptive…
As an optical element used to select or suppress light of a specific wavelength to achieve spectral control, the function of an optical filter is related to a variety of application environments, and also includes design parameters. The compliance of the parameters greatly affects the…
Narrowband filter is a special bandpass filter with a narrow passband range. It can accurately control the transmission of light of a specific wavelength and block light of other wavelengths. Usually, the half-width (i.e. bandwidth) of the passband of a narrowband filter is between a…
Optical glass refers to glass materials with specific optical properties, which are widely used in various components in optical systems. Optical glass can be divided into many types according to different optical properties, application requirements and material composition. Each type of optical glass has unique…
