Narrowband filter is the optical filter that suppressing the light source,sensor,natural light and isolating specific monochromatic spectrum.Narrowband filter is relatively cutoff interference light and transmit the particular wavelength.VY Optics pay more attention on the application field of customers.

Mainly application of narrowband filter:Semiconductor laser,security camera,sensor encapsulation,medical instrument,fluorescence microscope.
