850nm Narrow Bandpass Filter

Advantages OF Narrow Bandpass Optical Filter

High selectivity: Narrow bandpass filters can selectively pass light in a small wavelength range across a wide spectrum, which is particularly useful for applications that require the exclusion of background noise or interfering light.

Central wavelength: Each narrow bandpass filter has a specific central wavelength, which is the wavelength position of the maximum transmittance it is designed to pass.

Bandwidth definition: Bandwidth usually refers to the wavelength width (FWHM, i.e. full width at half maximum) corresponding to the transmittance falling to half of the maximum value. The FWHM of narrow bandpass filters is usually very small.

Precision: For applications that require precise control of spectral characteristics, narrow bandpass filters provide a high degree of selectivity and precision.

Multi-purpose: Different central wavelengths and bandwidths can be customized according to different application requirements, making them suitable for a variety of different occasions.
