The SS-120 measures a wavelength range of 635 to 1100 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).
THE SS-120 PACKAGE INCLUDES:
- Spectroradiometer unit and cosine corrected detector mounted in the housing
- 180° FOV head and black cap
- AL-200 bubble-level
- USB cable for computer interface
- 2GB USB drive with ApogeeSpectrovision software (Windows compatible, XP and later; Mac compatible, 10.10 and later) and required drivers
- Carrying case
