Interference filters are optical devices designed to reflect or transmit specific wavelengths of light.
Constructed from multiple transparent layers, these filters use light interference within each layer to selectively enhance or attenuate certain wavelengths. The interference principle, which varies depending on the light's wavelength, allows these layers to precisely filter light, isolating desired wavelengths for various applications.
They play a crucial role in fields that demand exact wavelength manipulation, including scientific research, astronomy, camera lens enhancements, and optical fiber communications, providing essential precision in optical requirements.
