Company Profile

The J.A. Woollam Company specialise in the manufacture and sale of spectroscopic ellipsometry equipment. All equipment is hand-assembled. Their alpha-SE ellipsometer offers patented technology giving accurate measurements on any substrate: metal, semiconductor, or glass. On transparent substrates, the alpha-SE® measures depolarisation to correct for light returning from the backside of the substrate. This unwanted light can confuse other ellipsometers, but the alpha-SE® ensures accurate optical constants. For routine measurements of thin film thickness and refractive index, the alpha-SE ellipsometer allows you to mount a sample, choose the model that matches your film, and press “measure”. You have results within seconds.
