Characterization of patterned and diffuse glass

The use of light-diffusing materials such as patterned cover glasses used in solar cells and textured/coated glasses used in buildings and greenhouses is increasing.
In solar cell applications, patterned glass captures and traps the light better within the structure ensuring maximum cell efficiency.

In greenhouses, the use of diffuse glass optimizes distribution of light for improved plant growth. The ability to measure the transmission and reflection properties of these materials accurately is a key requirement in the development and manufacture of high efficiency solar cells and light-diffusing glazing.

Integrating spheres are widely used for the reflectance and transmittance of light-diffusing samples. For many applications including diffuse reflection measurements small sphere accessories are an excellent choice. The increasing demand for accurate diffuse transmittance measurements however poses a challenge for smaller spheres.

OMT Solutions has developed accessories to be used on commercial spectrophotometers to determine these transmittance values very accurate.
For near-normal measurement but also for measurement at different angles of incidence
