Optical filters are essential components in a wide range of applications, from scientific research to industrial processes. Their performance is defined by a set of key parameters that determine their suitability for specific tasks. Understanding these parameters is crucial for selecting the right filter for…
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…
Optical filters are indispensable components in optical systems, used to select light of a specific wavelength or block unwanted light. Among the performance parameters of filters, cut-off depth (Optical Density, OD value) is a crucial indicator, which directly determines the filter’s ability to block non-target…
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…
