Collaborative construction of two “goniophotometers” for characterisation of optical materials.
In conjunction with engineers from Microsharp Corporation Ltd, LiveWires has built two “goniophotometers” (one of which is shown) for characterisation of optical materials. A collimated light source is shone through a sample, and the transmitted light collected by a detector.
Using Aerotech rotary stages and motors and National Instruments data acquisition hardware, the sample and detector are scanned through a series of pre-specified angles, to build up a 3D picture of the optical transmission properties of the material under test.
Such a 3D picture would take nearly an hour to compile with Microsharp’s previous generation goniophotometer, but the new system takes just 5 minutes, with the data being downloaded automatically to an Excel file.
Furthermore, the program can be used to compare several samples – as shown in the screen shot below.
