Description
Standardized measurement of floral reflectance spectra using fiber optic probe positioned at fixed distance and angle from flower surface. Spectra collected across 300-700 nm range for input into visual models.
Typical Equipment
- Avantes model 2048 spectrometer
- bifurcated coaxial fiber optic reflectance probe (Avantes FCR-7uv200-2-ME)
- AvaLight-XE xenon light source
- diffuse white PTFE tile (Avantes WS-2)
Output Measurements
- reflectance spectra
- spectral data 300-700 nm
