BTS2048-VL Integrating Spheres

For larger size LED fixtures or light sources with higher flux levels the BTS2048-VL spectroradiometer can be combined with a large size integrating sphere.

Large Size Integrating Spheres

Gigahertz-Optik offers a range of integrating spheres with sphere diameters from 210mm up to 1000mm. Four kinds of spheres are available:

  • Integrating spheres (2π) for spot lamps
  • Integrating spheres (4π) for bulb type lamps which measure the test source inside the sphere
  • All-purpose integrating spheres for bulb (4π) and spot (2π) lamps

The BTS2048-VL mounts to the integrating sphere port frame with set screws. This offers the flexibility to use the device by itself or combined with other accessory parts depending on the application.

Auxiliary Lamps for Self-Absorption Correction

All integrating spheres are supplied with auxiliary lamps to compensate for the self-absorption of the test sample (substitution error correction). The auxiliary lamp can be manually operated with other lamp power supplies or under remote control operation with Gigahertz-Optik's BTS256-LED-ALP power supply. Either way the substitution error correction routine is supported by the S-BTS software supplied. The software also controls all measurement functions with the add-on sphere.

Traceable Calibration

Calibration of the BTS2048-VL spectroradiometer with the add-on sphere is performed in Gigahertz-Optik's calibration laboratory for light measurement quantities against calibration standards traceable to national and international metrology laboratories. Re-calibration is recommended every 12 months. For in-house end-user re-calibration calibration standard lamps are available. The re-calibration routine is supported with the supplied software.

TFCT25 measurement system light guide from Gigahertz-Optic TFCT25
Spectral Transmission & Luminous Flux Measurement System

For lateral light emitting light guides used in transportation lighting

Lateral emitting light guides are now deployed in daytime running lights, tail lights and brake lights in the automotive industry. Gigahertz-Optik's TFCT25 measurement system can be used to measure the different optical transmission parameters, including light guide 'yellowing' and the LED lamps.

The system is based on a combination of the ISD-25 and BTS2048-VL.
