λT (nm)
Transmission Marginal Wavelength. which is the middle point of wavelength inclination range.
Δλ (nm)
Wavelength Inclination Range, which is the interval distance between transmission rate 5 % wavelength and 72 % wavelength
TH (%)
Transmission Rate in high transmission range, which is the average value of transmission rate within high marginal transmission range to 800 nm wavelength
λ5 (nm)
Wavelength for 5 % transmission rate.
λ80 (nm)
