The Light Measurement Laboratory has a library of optical data which
is accessible here. Most data were measured in our laboratory; data
from other sources is identified as such.
Light Source Spectra
We have accumulated wavelength spectra for several light
sources; all but one spectrum were measured in our lab.
Filter and Lens Transmission Spectra
We have measured transmission
spectra for various filters and lenses.
Camera Response Spectra
Wavelength sensitivity for various cameras is available here. These data were not measured in
We have measured reflectance data
for a variety of surfaces, using both our gonioreflectometer and our
image-based BRDF measurement technique.
