Filters are important components in optical systems. Their performance directly affects the image quality, light signal transmission efficiency, and the overall performance of the system. Therefore, confirming the performance of filters is a key step to ensure stable and reliable operation of optical systems. We…

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…

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…

Interference filter is an important device in optical technology. It uses the interference effect of light waves to selectively transmit or reflect specific wavelengths within the spectral range.
