λT (nm)
The transmission marginal wavelength, which is the middle point of wavelength inclination range.
Δλ (nm)
The wavelength inclination range, which is the interval distance of wavelength between wavelength of 5 % transmission rate and 72 % transmission rate.
TH (%)
Transmission Rate in high transmission range, which is the average of transmission rate from marginal high transmission wavelength to 800 nm wavelength.
