What is narrow bandpass filter?

Narrow bandpass filter is an optical device that allows the light of the specific wavelength to pass through the substrate, while blocking the light of other bands that are not needed. The band wavelength of the optical filter can be customized from ultraviolet light, visible light and infrared light, it is determined according to the scope of the application. Compared with other colorful filters, the narrow bandpass filter is difficult to design and production, mainly because the positions of the two ends of the spectrum peak need to be accurately controlled.

The 405nm narrow bandpass filter of Our company adopts the all dielectric hard coating technology and dielectric interference theory, which not only can highlight the characteristics of narrow bandpass filter, but also will not affected the optical properties by the thickness of the substrate, and it is easier for the built-in instrument imaging system. Optical properties are improved effectively. The special optical material substrate is adopted to solve the problems of traditional absorption of glass atomization and instability of optical performance.
