specbos 1211UV-2

Broadband Spectroradiometer 230 - 1000 nm

specbos 1211UV-2 extends the original wavelength range of the device in the UV range down to 230 nm, both in Radiance and Irradiance mode as well. All other parameters as sensitivity, viewing angle in Radiance mode (1.8°) and optical resolution remain the same as of the standard device.

This extension makes specbos 1211UV-2 suitable for hazard measurements according to the IES 62471 standard. Other applications are the measurement of UV exposure apparatus, suntanning banks etc.

Dome diffusor
The dome diffusor is equipped with a glass dom (silica for specbos 1211UV-2) and it is IP67 tested. It can be mounted on roofs or outdoor walls and allows a detection of the optical sky radiation. The standard length of the fiberoptic bundle is 3 m, so also longer distances between the measuring location and the indoor position of the measuring device can be spanned.

90° diffusor (ACC 012)
The standard diffusor of the device acts in line to the device. If the Illuminance at a low height above a surface needs to be measured, then the 90° diffusor can be applied. It is also available with attenuation filters to extend the Illuminance measuring range (ACC 012 ODx.x).

In axis remote diffusor (ACC 015-length)
If the measurement needs to be done in locations with limited space conditions then the remote diffusor can be used. It is a diffusor which is coupled to the spectraval device by an optical fiber bundle. The measurement is done in axis to the fiber bundle. Different fiber lengths are available.

90° remote diffusor, (ACC 019-length)
If the measurement needs to be done under limited space conditions and the in axis fiber coupled diffusor is not suited, then the 90° fiber coupled diffusor can be applied. Different fiber lengths are available.


Neutral density filters (ACC 010 ODx.x)
specbos 1211-2 can measure up to 25 000 cd/m2 (typical white LED spectrum). Additional neutral density filters allow to shift the measuring range towards higher Luminance levels.

Filter combination (ACC 030combi)
Filter for specbos 1211UV-2 with filter combination. Wavelength range 240 - 400 nm.
