980nm bandpass filter

980nm band-pass filter has the characteristics of wide-band pass, multi band pass, wide cut-off band and good film thickness. The peak bandwidth of nano macro photoelectric (nmot) to the central wavelength is greater than 20 η The products above M are defined as band-pass filters. The technology of multi-layer hard film coating is adopted to supplement the light flux and specific band coexistence requirements expected by customers in the middle of the product use process, and the starting and ending wavelength range of transmitted light can be strictly controlled. The products are produced according to the index needs of customers.
