We supply both PS (Lumieo_Glacier) and PMMA (Lumieo_Frost) diffusion plates. Standard sizes are available for convenient application, and custom cutting can be provided according to customer requirements. PS diffusion plates offer excellent chemical resistance, thermal stability, optical transmittance, and anti-static properties.
