specbos 1211-2

Broadband Spectroradiometer

specbos 1211-2 is a miniaturized and fast broadband spectroradiometer covering the wavelength range from 350 ... 1000 nm (the special version specbos 1211UV-2 extends the range in UV down to 230 nm). It can be used for various applications both in lab as well as in production and can measure in Radiance and in Irradiance mode based on its NIST traceable calibration.

Accessories

Diffusors

Diffusors with attenuation filter (ACC 013 ODx.x)
specbos 1211-2 with its standard diffusor can measure up to about 150.000 lx (typical white LED spectrum). If it is necessary to measure higher Illuminances, then a special diffusor with additional attenuation filter can be used. It is possible to measure illuminance up to 1.500.000 lx.

Fast diffusors (ACC 013 Med, ACC 013 High)
If low Illuminance levels must be measured, then the measuring time will be long when using the standard diffusor of the device. It is possible to use “fast” diffusors, but only if the cosine matching of the diffusor is not of primary importance, e.g. in case of point like sources.

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.

Filters

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.

Dolby/realD filter cap pairs
The calibration of 3D projectors needs to be done through the right and left eye glasses. specbos 1211-2 can be equipped with caps containing the filters of Dolby (ACC 014) and realD (ACC 017) projection. The usage of these filter pairs allows a precise measurement of these 3D projection systems.

VIS filter (ACC 016)
specbos 1211-2 can be equipped with a VIS filter to reduce its wavelength range to 380 … 780 nm. This is especially interesting for measurements with a low VIS intensity but much signal in IR or UV.

Focusing optics

Focusing Optics for small spot sizes
specbos 1211-2 in its standard configuration can measure in Luminance mode only with diameters of 4 mm and more. Applications as the measurement of small segments of displays or small sized OLEDs may need smaller diameters. Therefore, JETI offers three focusing optics to reduce the measuring diameter.

Integrating spheres

Radiant and Luminous flux measurements can be done with specbos 1211-2, if it is mounted on an integrating sphere. The port and baffle design are compatible to the LM-79 and similar standards. Default sphere diameters are 300 and 500 mm, other diameters are possible on request. The sample ports are compatible to 1.5” LED holders. Another port design is possible on request.

300 mm sphere (OPS300)
This sphere with an inner diameter of 300 mm can be used for 2π measurements as LEDs.

500 mm sphere (OPS500)
The sphere with a diameter of 500 mm is hinged, therefore it can be used for 2π and 4π measurements as well. It contains an auxiliary lamp, which can be darkened by a manual shutter.

Only specbos 1211UV-2

Photobiological measurements complete (according to IEC 62471)
specbos1211UV-2 can be upgraded to a measuring system for photobiological safety. Special accessories for BlueLightHazard, Retinal Thermal, Eye IR, Skin Thermal and Actinic UV/ UVA are available.

Radiance based hazard measurements (ACC 024)
The following hazard measurements are radiance based:

  • Blue Light Hazard
  • Rhetina thermal
  • Rhetina thermal (weak visual stimulus)

These measuremants must be taken with determined viewing angles.
Two front optics creating viewing angles of 100 mrad and 11 mrad are avaiable.

Additional attenuation filters are included in the delivery to allow to measure Luminance levels as high as 50.000.000 cd/m2. Additionally, tilting/ turning elements (ACC 025) are available to adjust the meter towards the region of the source with the highest Radiance.

Irradiance based measurements (ACC 026)

The following hazard measurements are Irradiance based:

  • Artinic UV
  • UVA
  • Eye IR
  • Skin thermal
  • Blue Light Hazard small source

The measurements are carried out with a special diffusor with a measuring diameter of 8 mm, conform to the standard IEC 62471. Additionally, an 80° aperture for the diffusor (ACC 027) is available to fulfil the regulations of IEC 62471 to be applied in case of extended UV sources.
