Total light transmission.
Specular and diffuse reflection. Performed at a 5º angle.
Wavelength range: 185 - 2500 nm.
Spectral resolution: 0.1 nm. Data collection intervals between 0.01 - 5 nm (1 nm commonly used).
Double beam instrument: Reference beam corrects for fluctuations in, e.g., the light source intensity or detector response, over time.
Detectors to cover the whole range from UV to NIR in the same scan:
Automatic dark correction: spectrometer automatically corrects measurements in the NIR to account for blackbody radiation from the instrument.
