Here, the cut-off wavelength refers to a wavelength at which the transmittance becomes 50% in a long pass filter, for example, and the cut-on wavelength in FIG. 6 is 650 nm.
9 (a) is a graph showing the transmittance versus wavelength of the long-pass filter. Specifically, referring to FIG. 9A, the cut-off wavelength generally represents a wavelength at which a transmittance of 50% is exhibited in the long-pass filter. At this time, most rays pass through the long-pass filter at the wavelengths higher than the cut-off wavelength, and most rays do not pass through the long-pass filter at the wavelengths below the cut-in wavelength. Here, the meaning of "most" means that light that does not pass through the filter among light having a wavelength higher than the cut-on wavelength, and light that is not blocked (reflected or absorbed) in the light having a wavelength below the cut-on wavelength.
However, if the slope of the transmittance relative to the wavelength is steep in the region near the cut-off wavelength, more rays among the rays in the wavelength region above the cut-off wavelength can be transmitted through the filter, and among the rays in the wavelength region below the cut- More rays can be blocked from passing through this filter.
Referring to FIG. 9 (a), as the wavelength becomes larger than the cut-off wavelength, the transmittance gradually increases from 50% to reach the maximum transmittance. Therefore, in order to pass all the rays above the cut-off wavelength, the slope of the transmittance relative to the wavelength should be steep in the region near the cut-off wavelength.
Referring to FIG. 9A, below the cut-off wavelength, as the wavelength decreases, the cut-off rate increases from 50% to the maximum cut-off rate. Therefore, in order to block all rays below the cut-off wavelength, the slope of the transmittance relative to the wavelength should be steep in the region near the cut-off wavelength. The first

Here, the cutoff wavelength refers to a wavelength at which the transmittance becomes 50% in a short pass filter, for example, and the cutoff wavelength in FIG. 7 is 645 nm.
9 (b) is a graph of transmittance versus wavelength of a short path filter. Specifically, referring to FIG. 9 (b), the cutoff wavelength generally refers to a wavelength at which the transmittance is 50%. At this time, most of the light rays can not pass through this filter at the wavelengths above this cutoff wavelength, and most rays pass through this filter at the wavelengths below this cutoff wavelength. Here, "most" means light passing through the short-pass filter in the light having the wavelength longer than the cut-off wavelength, and light not passing through the short-path filter among lights having the wavelengths below the cut-off wavelength.
However, if the slope of the transmittance relative to the wavelength is steep in the region near the cutoff wavelength, more of the light rays in the wavelength range above the cutoff wavelength can not be transmitted through this filter, and among the light rays in the wavelength region below the cutoff wavelength So that more rays can pass through this filter.
