Photometry to determine material properties
Material properties is a general term used to refer to the reflection, transmission and absorption properties of a material. Photometry hereby refers to a measurement process through which these properties are determined using a photometer.
Integrating sphere photometer
The integrating sphere is very common in both broadband and narrow-band photometric applications for diffuse sample illumination and determination of the reflected and transmitted light proportions.
UPB-150-ART precision integrating sphere
With the 150mm diameter, the UPB-150-ART provides a good compromise in terms of precision of the sphere function and level of the measurement signal. Its manufacture from an aluminum block ensures a very precise alignment of the measurement ports to each other. Another characteristic property are the thin circumferential knife-edges of the measurement ports that enable a high acceptance angle for diffuse light.
Multifunctional integrating sphere
The UPB-150-ART is ideal for multiple functions through its five knife-edged measurement ports that can be used either while open or closed. Possible measurement setups include:
- 0°/d Reflection
- 8°/d reflection with and without glamour
- 0°/d directed and diffuse transmission
- Measurements with correction of sample absorption effects
- Two-ray measurement setups Luminous flux measurements
Accessories for individual sphere assemblies
Port plugs and port reducers that can easily be fixed and removed using the Slide & Fix holder are offered for either closure or reduction of ports. An important feature of the UPB-150-ART is that the front side of the plugs and reducers projects into the port and is therefore on the same level as the sphere surface.
Universal sample holder
The sample holder is fixed onto the posts of the Slide & Fix holder and ensures secure mounting of thin and thick samples. An important feature of the Slide & Fix system is that the sample holder can be combined with port reducers and a light trap.
Light trap with Slide & Fix holder
The light trap has a 30mm input port and ensures minimal back reflection over the entire usable spectral range of the integrating sphere through its internal design and black absorbing coating. The Slide & Fix holder can be used to combine the light trap with port reducers and the sample holder.
Ex-changeable holders for detectors and light guides
Ex-changeable adapters are offered for mounting of detectors and light guides. Each has a baffle that can be aligned to one of the five measurement ports accordingly depending on the measurement application. The UMPA port adapter of our modular integrating spheres can hereby be used. It is also possible to connect one of our fiber-coupled spectrometers BTS2048-VL-TEC-F or BTS2048-UV-F.
Reflection coating made of barium sulfate
The UPB-150-ART is coated with Gigahertz-Optik‘s self-manufactured diffusely reflective barium sulfate (ODP97) coating. The multi-layer coating ensures good diffuse reflective properties over the entire usable spectral range.
Positions of the five measurement ports of the UPB-150-ART enable its universal application.
The front side of the port plugs, port reduces and sphere surface are at the same level and thus ensure an almost ideal reflection surface.
Light trap for absorption of the transmitted light of transparent samples in 8°/d reflectance measurement setup. Combined with port reducer.
