describe

A bandpass filter is an optical component that selectively transmits light within a specific wavelength range while blocking light in other wavelength ranges. Bandpass filters are usually composed of multiple layers of optical films, which achieve transmission and blocking of specific wavelengths through the principles of interference and reflection. This type of filter can be used in optical systems for spectral analysis, imaging, lasers, and other applications, playing a role in selective transmission and filtering of specific wavelengths.

General

Features and advantages

• Wavelength selectivity: A bandpass filter selectively transmits light within a specific wavelength range and can be customized to different wavelength ranges as needed.
• High transmittance: For light within a specific wavelength range, bandpass filters typically have high transmittance, ensuring the brightness and clarity of the optical system.
• Wavelength resolution: Bandpass filters have high wavelength resolution and can effectively separate light of different wavelengths.
• Suppressing stray light: Bandpass filters can effectively suppress stray light in non target wavelength ranges, improving imaging and measurement accuracy.
