Avantes has introduced the AvaSphere-50-LS-HAL, an integrating sphere that can be used for reflection measurements with diffuse halogen light as illumination and a direct collimated SMA measurement port for reflection signal sampling to connect to AvaSpec spectrometers.
The AvaSphere-50-LS-HAL is the ideal combination of an integrating sphere with an internal halogen light source. The advantage of the internal halogen light source is a factor of 160 times more light on the sample than with an integrating sphere and external fibre-coupled light source and is therefore mostly suitable for dark reflecting materials and NIR spectral measurements. The AvaShpere-50-LS-HAL 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 forced airflow. It comes with a 24V/1.25A power supply.
