STS Software

supporting software across all systems

All Sapphire photometry systems run on proprietary subscription-based software developed in house specifically for our machines and client applications. By licensing software annually, we ensure that our customer’s photometry systems have the latest updates and patches as well as access to support from our team of developers for the life of the product.

Our various software applications are listed below in more detail. If you have additional questions, see if we’ve answered them on our Software FAQs page.


BeamScale HF

Our BeamScale HF software analyzes lighting data files (standard IeS format) and is used primarily by the automotive industry to simulate and calculate the amount of light that will strike pre-defined target areas when both headlamps on a vehicle are illuminated.

This proprietary software is the latest photometric beam pattern analysis software available from STS and is used for post-processing of IeS files generated by our line of goniophotometers and VOa systems. It is used to analyze the beam patterns of automotive forward lighting products and can process multiple files at once to evaluate real world performance-based objectives.

New technology such as matrix beams, adaptive Forward-lighting System (aFS) and adaptive Driving Beam (aDB) can be evaluated for performance-based characteristics including, but not limited to:

  • Beam spread

  • Beam reach

  • Uniformity

  • Glare evaluation

  • Hot spot / dark spot discovery

Other features:

  • Analyzes full vehicle results with output of combined lamps

  • Customizes files based on your needs

  • Calculates IIHS rating for vehicle

  • Calculates lux values for Consumer Reports posts

  • Outputs results in Microsoft Excel file format for further analysis

  • Future protocols – National Highway Transportation and Safety administration (NHSTa) and New Car Assessment Program (NCAP)



PhotoScale is our standard testing software package for the AP series. It includes

  • Point-to-point testing, line and box scanning

  • Integration with standard user station computer with Windows7 Pro, Ethernet, and printer

Strobe & Flashing Light Testing Package

This is our enhanced software package for AP series goniometers for testing strobe and flashing lighting products.

  • Allows for automated measurement of effective candela, flash energy (cd/sec), flash duration, flash period, and flash peak

  • Allows for measurement of strobe and flashing light devices as anisocandela if combined with BeamScale software package

  • Measures emergency vehicle lighting, automotive and aerospace flashing and strobe lighting, and more
