Photoluminescence mapping is a non-contact, non-destructive technique for mapping out uniformity of alloy composition, material quality and defects in substrates and of III-V epiwafers. The Rapid Photoluminiscence Mapper (RPM) is equipped with 3 lasers for PL measurements and a white-light source to map out thickness and reflectance of eg layers, microcavities and VCSELs. | Photoluminescence mapping is a non-contact, non-destructive technique for mapping out uniformity of alloy composition, material quality and defects in substrates and of III-V epiwafers.
