Home / Custom / Optical Components / Optical Filter / Narrow Bandpass Filter 
Based on the technique of all-dielectric hard coating and the principle of dielectric interference, and based on the characteristics of narrow-band optical pass filters, the optical properties are independent of the substrate. The narrow-band filter produced by Ecoptik China is more convenient to be built into the instrument imaging system so that its optical performance can be improved and effectively applied.
