The software allows the full control of the device settings like integration time, measurement settings, mathematical corrections, evaluations, etc.

Several numerical and graphical displays

The S-BTS256 software contains several numerical and graphical displays for visualization of your measured data. These displays are user selected from the view menu and can be positioned anywhere within the application window. Each individual display arrangement can be stored and reloaded. Furthermore two different color schemes are offered, normal and dark room mode with darker background to prevent stray light from the display from reach the detector.

Numerical windows:

  • spectral values
  • color values
  • CRI (color rendering index)
  • CQS
  • intensity and set-up parameters
  • commment/status
  • measurement settings
  • integral values
  • TM-30-15
  • etc.

Graphic windows:

  • spectral plot
  • CIE 1931 Chromaticity Diagrams
  • CIE 1976 Chromaticity Diagrams
  • polar plot 2D by goniometer measurements
  • polar plot 3D by goniometer measurements
  • datalogger
  • CRI (color rendering index)
  • CQS
  • TM-30-15
  • L*a*b*
  • etc.

Binning classification

For LED binning additional graphic layers can be shown within the CIE 1931 diagram like the Planckian locus, ANSI or MacAdam Ellipsen. These graphical layers can be used to classify your test samples. Additional layers can be defined by each user individually.

External devices

In addition devices like power supplies or goniometers can be controleld with the S-BTS256. As well external devices like a Keithley 2400.

Self-Absorption Correction (Substitution correction)

The self-absorption correction (often substitution correction called) set-up screen in the S-BTS2048 software prompts the end-user through the self-absorption correction routine for the BTS2048 light meter with an optional integrating sphere. The routine includes automatic control of the integrating sphere auxiliary lamp and Gigahertz-Optik power supply if supplied.

Re-calibration

In the S-BTS256 software a re-calibration routine is implemented to perform re-calibrations with optional calibration equipment of Gigahertz-Optik very easy.

Data Export to common file formats

Data can be exported in different formats (IES, Eulumdat, ASCII, Microsoft Excel)

IES format (only with goniometer): IES stands for Illuminating Engineering Society. IES standard file format was created for the electronic transfer of photometric data. It has been widely used by many lighting manufacturers and is one of the industry standards in photometric data distribution.

EULUMDAT format (only with goniometer): EULUMDAT is a format for electronic transfer of photometric data. The typical file extension is “*.ldt“. The format was created 1990 and is a de facto standard in European industry.

Database

The S-BTS256 is bassed on a database architecture, this allows the handling of a large number of measurements. Furthmore datasets can be easily saved, loaded and exported.

Extension tools

The software can be extended by tools like a user control management, automatic complex measurement sequences, etc. Furthermore customized tools can be developed and integrated.

Report Generation

Based on the database an export of measurement data to an Microsoft Word file is provided. The data which is exported is customable by the user.
