Holographic Surface — Diffraction Grating Abstract
319.00 $
A photographic close-up of a holographic diffraction grating surface illuminated by white light — the full visible spectrum arranged as concentric rainbow bands across the frame.
Description
Diffraction grating sheets — the same technology used in holographic security stickers and concert laser shows — produce a colour spectrum effect of extraordinary purity and precision when photographed under a controlled single-source white-light illumination at the correct angle. This photograph was made by illuminating a precision optical diffraction grating (1,200 lines per millimetre) with a tightly collimated beam from a cold-cathode light source and capturing the resulting spectral dispersion pattern across the grating surface. The photograph resolves individual diffraction orders as distinct colour bands, creating a composition of exceptional optical precision. The image is used commercially in optical science communication, luxury packaging design reference, and premium interior decoration.
