SPECTRAPEN MEASURES

Scope – rough spectrum data
Absorbance (external sample holder and light source needed)
A=log(I0/I), where I0 is reference light intensity and I is measured light intensity

Transmittance (external sample holder and light source needed)
T= I/ I0, where I0 is reference light intensity and I is measured light intensity
