SS-110 Apogee Field Spectroradiometer (340 to 820 nm)

The SS-110 measures a wavelength range of 340 to 820 nm. The spectroradiometer is an easy-to-use, cost-effective, versatile spectral measurement system that can be interfaced to a computer. Typical applications include measurement of spectral output (energy flux density, photon flux density, or illuminance) of different radiation sources (often for plant or human lighting), and reflectance and transmittance measurements of natural and synthetic surfaces and materials (often plant leaves and canopies).
