R70-50-2.5~ detailed data sheet

< Standard Value >

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): Wavelength for 80 % transmission rate.
