- Abstract:
- This study presents a performance comparison of low-cost, spray-applied reflective coatings for use on custom 3D-printed substrates, targeting visual stimulation applications such as ophthalmic prototypes. BaSO4 and TiO2 mixtures were evaluated against commercial references under broadband illumination to assess their spectral uniformity and practical applicability. While TiO2 achieved higher reflectance in the red-NIR region, BaSO4 demonstrated more balanced performance across the visible spectrum and superior adhesion. Standard white paints showed significantly lower and inconsistent reflectance, highlighting their inability to serve as reflectance standards.
