    Abstract: A method for designing and depositing rectangular wave broadband-pass filter is put forward after a deep study of the nature of the film-filters. A rectangular wave OD3-A broadband-pass filter sample is designed and prepared with this method, with its reference wavelength λ0 = 515nm in the working range of 400~1100nm. The average transmittance of t... Show More
