The BS-03 is a medium-sized, rugged irradiation chamber for time- or dose-controlled irradiation of samples with UV or visible light. The chamber can be fully equipped for one of the spectral ranges UVC, UVB, UVA, or daylight D65 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 interior irradiation chamber has a base area of 68 x 48 cm and a height of 25 cm. The sliding sample carrier facilitates loading and unloading. With a load of up to 20 kg, this can withstand all demands. The sample chamber operating temperature is about 25°C so that thermal damage to the specimen is avoided. Due to the high uniformity of the irradiation, the samples may be positioned in any order.
The optional UV-MAT irradiation control can separately control two different spectral ranges and obtain a constant dose regardless of lamp aging, pollution, or temperature. UV-MAT irradiation control continuously measures the irradiance and determines the target irradiation dose. Radiation doses for different spectral ranges can be controlled separately. Therefore, calibrated radiometer sensors are used.
The integrated diffuser ensures the required cosine correction. Excellent long-term stability is achieved through the use of appropriate materials. The sensors are calibrated with traceability to PTB (Physikalisch Technische Bundesanstalt, the German national test authority); after being calibrated, they are supplied with a factory calibration certificate.
