its core purposes. The facility caters to users from various levels of experience and technical backgrounds within the university and serves commercial customers as well. The user community today is more than 100. The PL capabilities of the instrument will be used by thin-film semiconductor growers. Materials to be measured range from epitaxial III-V semiconductors with bright, narrow emission to emerging semi-conductors with often weak, broad emission. The reflectance capabilities will mainly be used to measure distributed Bragg reflectors. Different users may have very different experience levels with optical measurement setups. Therefore, it is important that the setup is easy to use, with a high level of automation, and with no hands-on user intervention needed expect for sample loading. The instrument must be able to do the following: • Obtain accurate PL and reflectance spectra
