Product Details
Product Description
Narrowband filter comes from the bandpass filter in the subdivision, its definition and band-pass filter is the same. This kind of filter in a particular band to let light signal through and departed from outside the band on both sides of the light signal is blocked. The narrowband filter passband is relatively narrow, usually at the center wavelength value of less than 5%.
The bandpass filters specially manufactured by Wuhan Especial Optic adopt the technology of all-dielectric hard film coating and the principle of medium interference. On the basis of highlighting the characteristics of narrowband filters, the optical properties are independent of the thickness of the substrate. The narrowband filters manufactured by Wuhan Especial Optic are more convenient for the built-in instrument imaging system. The special optical material base is used to solve the problems of fogginess and instability of optical properties of absorbent synthetic glass in the traditional sense. The products are manufactured according to customer's requirements.
