Strengths & Limitations

Strengths

  • +High reliability due to peer-reviewed sources
  • +Open-source accessibility

Limitations

The database is technical; students may find the YAML files hard to read without a converter or the website interface.

Reliability & validity

High validity as it uses cross-referenced peer-reviewed data; high reliability due to standardized digital formatting.

Think critically

Why is it important for designers to use open-source databases rather than proprietary manufacturer data that might be biased?

05

Design Principles

"Data Fidelity: The accuracy of a digital model is directly proportional to the quality and standardization of the input material data."

In design, modelling is essential for predicting product performance before physical prototyping. This research highlights how standardized data formats (YAML) and metadata integrity are critical for the 'fidelity' of mathematical and CAD models, particularly when selecting materials like glass, plastics, or composites for optical functions.

What This Means for Your Design

If you are designing something with light or lenses, using the exact 'refractive index' from a professional database makes your computer models way more realistic.

Paragraph starter

To ensure high-fidelity digital modelling, optical constants were sourced from the refractiveindex.info database (Polyanskiy, 2024). This ensured that the CAD simulations for the lens component accurately reflected the refractive properties of Polycarbonate, rather than relying on generic software presets.
