# 4. Aesthetix Modules: Operation, Measurement parameters and how to interpret results 

The Rhopoint Aesthetix system employs a modular approach to surface characterization, allowing users to tailor their measurement capabilities to specific needs. 

This modular format offers significant flexibility and cost efficiency, as users can pay only for the measurement capabilities they require.

## Module Concept

The Aesthetix system comprises several measurement modules, each designed to analyze specific surface characteristics:

1. **Surface Brilliance Module**: Measures gloss, visual gloss, haze, sharpness, distinctness of image (DOI), waviness, luminance, and RGB color.
2. **Effect Finish Module**: Ideal for coatings with effect pigments, measuring coarseness, RGB color, luminance, haze, sparkle density, sparkle visibility, waviness, and gloss.
3. **Surface Texture Module**: Suited for textured surfaces, measuring cell amplitude, count, size, reflectivity, luminance, RGB color, and gloss.
4. **Polishing Quality Module**: Simultaneously measures glossiness, haze, polishing defects, and scratches.
5. **Cross-cut Adhesion Module**: Objectively quantifies the results of adhesion strength tests.

## Licenses and Demo Options

Rhopoint offers flexible licensing options for Aesthetix modules:

1. **Full Licenses**: Customers can purchase licenses for individual modules or bundles directly from Rhopoint Instruments.
2. **Demo Licenses**: Rhopoint provides free limited time demo licenses to qualifying Aesthetix users.

## Adding New Licenses

To add new licenses to your Aesthetix system:

1. **Contact Rhopoint or Premium Rhopoint Distributor**: Reach out to Rhopoint directly via email at [sales@rhopointinstruments.com](mailto:sales@rhopointinstruments.com).
2. **Discuss Requirements**: Talk with an application specialist to determine your specific measurement needs.
3. **Purchase Licenses or Free Demo**: Buy a new license or obtain a free demo to try out a new module.
4. **Activate Licenses**: Rhopoint will provide instructions for activating the new licenses within your Appearance Elements software.

The modular design of the Aesthetix system ensures that it can evolve alongside changing requirements. Rhopoint continuously develops new software modules, allowing customers to expand their measurement capabilities as new features become available.
