Multispectral Specimen Index

Catalogue comparing light reflection, absorption, and structural signatures across:

Wavebands using full-spectrum sensor rigs and bandpass filters.

To be added / notes

UV re-emissions (i.e. visible light (neon colours) from UV, what most people think of)
NIR-bandpass filter (falsecolour from my DSLR to contrast visible light, my other NIR photography)

Botanical & Flora

Specimen	Visible (VIS)	Near-Infrared (NIR)	Ultraviolet (UV)	Spectral Notes
Mountain Ash				High NIR foliage bounce; UV berry absorption.
Rose Hips				Cuticle wax UV bounce vs dark NIR contrast.
Himalayan Blackberry				Dynamic NIR leaf bloom; drupelet UV signatures.
Oregon Grape				Heavy waxy leaf coating UV scattering.
Morning Glory / Moonflower				Floral throat UV bullseye target guide.
Lavender				Trichome/essential oil UV reflectivity.
Lavender Yarrow				Cultivar pigment response vs core UV guide.
Himalayan Balsam				Petal absorption gradient into UV band.
Black-Eyed Susan				Striking UV absorber center target.
Daylily				Anther/petal contrast & UV guide spots.
Meadow Dandelion				Strong UV absorption pattern across florets.

Specimen	Visible (VIS)	Near-Infrared (NIR)	Ultraviolet (UV)	Structural Notes
Blue Jay Feather				Tyndall structural blue drops out in NIR (melanin base remains).

TBD

Specimen	Visible (VIS)	Near-Infrared (NIR)	Ultraviolet (UV)	Bandpass/Absorption Notes
Sunscreen Application				Invisible in VIS/NIR; jet-black absorbing layer in UV. (Chemical/carbon-based blocks, mineral-based scatters
Clear Corrective Lenses				Transparent in VIS/NIR; opaque UV-blocking coating block.
