What is a Optical filter?
Optical filters are components that selectively transmit or reflect specific wavelengths of light. This enables the control of the color or intensity of light. There are various types of optical filters, such as band-pass, low-pass, high-pass, and ND (neutral density) filters, designed for different applications. They are widely used in scientific analysis, photography, laser processing, astronomy, and display technologies. In environments requiring high precision, the performance of optical filters significantly impacts the accuracy of results.
Application of Optical filter
✅Spectroscopy
Band-pass filters are used to isolate specific wavelength ranges for chemical composition analysis.
✅Photography
ND filters help maintain proper exposure in bright conditions, preventing overexposure in photos.
✅Laser devices
High-pass filters eliminate unwanted low-energy wavelengths, enabling precise material processing.
