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.
