Micro-spot DUV Reflection and Transmission Spectrophotometry
The FilmTek™ 3000 PAR combined reflection-transmission spectrophotometer provides efficient and accurate measurement of patterned films deposited on transparent substrates. It is ideally suited for measuring the thickness and optical constants of very thin absorbing films.
The FilmTek™ 3000 PAR utilizes SCI’s patented parabolic mirror technology to achieve a small spot size down to 50µm.
This system comes with advanced material modeling software to make even the most rigorous of measurement tasks reliable and intuitive. FilmTek™ software includes fully user-customizable sample mapping capabilities to rapidly generate 2D and 3D data maps of any measured parameter. In addition to user-defined patterns, standard map patterns include polar, X-Y, rθ or linear.
FilmTek™ 3000 PAR incorporates SCI’s generalized material model with advanced global optimization algorithms for simultaneous determination of multiple film characteristics.
