[0029] figure 1 It is the transmission spectrum curve of the blue glass substrate (model QB51) of the existing cut-off filter. like figure 1 As shown, the blue glass substrate not only has a poor steepness in the transmission-cut transition region, but also has a poor cut-off in the infrared region, so its thickness needs to be increased to 0.5mm. However, even if it is compared, its steepness can only barely meet the requirements of use (such as figure 1 shown), and the efficacy of blocking infrared light and ultraviolet light must rely on cut-off filters to complete.
[0030] figure 2 It is the transmission spectrum curve of the blue plastic substrate (model FLXL100AA) of the existing cut-off filter. figure 2 Although the blue plastic substrate shown is only 0.1mm thick, the steepness of the transmission-cutoff transition region is relatively figure 1The blue glass substrate shown is a marked improvement. However, the disadvantage is that compared with the blue glass...
