BSM-03 – broadband UV irradiation with Hg medium-pressure lamp
The BSM-03 UV curing chamber with an output of 2 kW is best suited for large-area UV curing, hardening, and bonding. The internal shutter is controlled by the UV-MAT for an accurate dose so that reproducible exposure is achieved even with medium-pressure lamps. With irradiance of 150 mW/cm², the required dose is typically achieved within several seconds.
Whether the required dose is reached can be checked with our UV meters and radiometers.
The UV curing chamber can be opened for loading and unloading while the lamp is on. The shutter is monitored and closed with a safety circuit so that no UV radiation is emitted outside the chamber. The sliding sample support also facilitates loading and unloading.
The medium-pressure lamp delivers broadband UV irradiation rather than individual lines – that is the difference from a low-pressure or LED chamber, and the reason formulations with an unknown photoinitiator can be cured here.
The sample support withstands loads of up to 20 kg. With a base of 60 × 40 cm and a height of 25 cm, the irradiation room offers plenty of space. The sample chamber temperature is approx. 45 °C in operation. Thanks to the high uniformity of the irradiation, the samples can be positioned anywhere.

Equipment in detail
The curing chamber has a modular design and can therefore be adapted to different applications. These functions are always included:
![]() | Dose control The UV-MAT irradiation control measures the irradiance continuously and ends the irradiation once the set target dose is reached. It controls the internal shutter for this, so the irradiation remains independent of lamp ageing, soiling and temperature. |
![]() | Sensor The calibrated radiometer sensor serves as the measuring head for the dose control. The integrated diffuser provides the required cosine correction. Suitable materials give the sensor excellent long-term stability; it is calibrated traceably to PTB standards, can be recalibrated and is supplied with a factory calibration certificate. |
![]() | Sensor holder The sensor holder fixes the radiometer sensor at the side of the chamber. For measurements on the sample the sensor can be removed, so that the irradiance can be determined at the required position. The UV-MAT can be adjusted to this by a factor. |
![]() | Timer As an alternative to dose control we offer an adjustable timer. It suits simple irradiations between 1 s and 500 h. |
![]() | Lamp dimming Lamp dimming allows the irradiance to be varied. It is set on the UV-MAT. |
Order numbers, scope of delivery, accessories and versions
| Version | Order number |
|---|---|
| BSM-03 | 860913 |
The chamber is supplied with lamp, sensor holder and control; please state the required lamp type with your order. The scope of delivery comprises the BSM-03, the mains cable, the manual, the UV lamp (ozone-free unless specified otherwise) and the sensor holder.
The leakage current of the built-in SINAMICS V20 inverter can exceed 3.5 mA. A permanent earth connection is therefore required.
| Version | Order number |
|---|---|
| UV-MAT | 820920M |
The chamber is controlled by the UV-MAT. It measures the irradiance, controls the internal shutter and switches off once the target dose is reached.
| Lamp type | Order number |
|---|---|
| Replacement lamp Hg | 860813H |
| Replacement lamp Fe | 860813F |
| Replacement lamp Ga | 860813G |
The medium-pressure lamp is available with three dopings: mercury (Hg), iron (Fe) and gallium (Ga). They differ in their spectrum and therefore in their curing effect.
| Designation | Order number |
|---|---|
| Sensor holder | 86080H |
The radiometer sensors each carry their own number depending on the spectral range (number range 8144XX); you will find them under radiometer sensors.
