“…Automatic optimization method make full use of computer resources to optimize the membrane systems. the needle optical method with excellent spectral characteristics is developed in recent years, which can be tunneling from a local extreme value to another local extreme value, and solved some extent optical thin film design problems automatically [5]. Using the needle method, combined with genetic algorithm and simplex method, a variety of automatic optimization method combined with each other, and finally get to meet the requirements of the design spectrum.…”

In order to image no color cast in daytime, and form black and white image at night, we use day and night filter to instead mechanical switching system in infrared night vision camera and monitoring system. Essential Macleod software is used to optimize the film spectra, the average transmittance exceeds 90% in 440~640nm. The spectra has a band pass in 850nm, the bandwidth is less than 40nm, and the peak transmittance is less than 20%. Physics vapour depositing method with the aid of ion beam assistant deposition systems is adopted. Through reducing film thickness error and optimizing technical parameter, we get the new type day and night filters on substrate of K9 glass.
