Integrated Halogen Source & Reflection Integrating Sphere

Halogen integrating sphere

In comparison to using a standard reflectance integrating sphere and light source, the AvaSphere-50-LS-HAL-12V provides up to 160 times more light on your sample for a reflection measurement, and is a valuable instrument for reflection applications.


It's a combination of an integrating sphere and a halogen light source. The sphere provides diffused halogen light on your sample without the losses associated with fibre optic coupling. It has a direct collimated SMA port for collection of the reflection signal with any of our AvaSpec spectrometers.

It’s especially useful for dark or low reflecting materials and NIR spectral measurements where signal strength can be limited. It is also very useful for measuring gem stones - in the application section of this website, a complete typical gemmology setup can be found.

The AvaSphere-50-LS-HAL-12V has an internal diameter of 50mm, a sample port of 10mm and an SMA terminated reference port. The 5W halogen lamp is stabilised and cooled with a forced airflow.


A 12V power supply is included.  The switch line makes it possible to remotely switch the ligthsource on/off with a TTL signal.
