The 3D UV test chamber BS-05 is a large irradiation chamber for double-sided, 3D irradiation of samples with UV or visible light. A sample plate made of stainless steel or fused silica or a rotating holder for mixing of fluids are available. Like all BS irradiation chambers, the BS-05 offers time- and dose-controlled irradiation of samples with UV light.

The chamber can be fully equipped for one of the spectral ranges UVC, UVB, or UVA to achieve the highest irradiance. Alternately, the use of two separately controlled lamp groups for different spectral ranges allows for especially flexible operation of the chamber.

The large irradiation chamber of the test chamber has a base area of 86 x 65 cm² and a height of 32 cm. The maximum sample chamber temperature during operation is approx. 25 °C, so that thermal damage to the samples is avoided. Due to the high homogeneity of the irradiation, the samples can be positioned as required.

For the BS-05 we offer two irradiation controllers, the UV-MAT and the UV-MAT Touch. Both irradiation controllers can control two spectral ranges separately and achieves a consistent dose regardless of lamp aging, contamination or temperature. The dose is measured with calibrated sensors. For this purpose, the sensor already contains an extremely precise analog-digital converter and a temperature sensor.

The memory in the sensor contains all sensor identifications and the calibration history.

The UV-MAT Touch user interface is a high-resolution capacitive touchscreen. A powerful Cortex ARM processor ensures durability and updateability. This means that new functions can be installed directly on site.  The UV-MAT Touch and the PC software are Windows 10/11 compatible.
Numerical and graphical single and multi-channel irradiations, oscillograms and the settings are clearly displayed. The parameterization is done intuitively directly on the UV-MAT Touch and is password protected.

The UV-MAT Touch also records the irradiations and can be controlled by the PC. This makes multi-stage irradiations and the documentation of the irradiation possible.
