OPTX™ Reflectometers
OPTX™ reflectometers are an accurate and affordable solution for routine measurement of thin film thickness and refractive index. Each instrument combines a fixed-grating CCD spectrophotometer with our intuitive, high-performance material modeling software to make daily measurement tasks fast, reliable and simple.
OPTX™ reflectometers are available in three configurations to meet your specific application needs.
OPTX-R
Our base model, which allows for rapid, accurate, and intuitive measurement capabilities for most thin film measurement applications.
OPTX-RT
Adds transmission measurement capabilities, and excels in analysis of both transparent and non-transparent substrates.
OPTX-RM
Adds a microscope base with a manual stage and multiple objectives for applications requiring a small spot size. An optional CCD camera is available for displaying the measurement location on the computer monitor.
A UV option is available for OPTX-R and OPTX-RT models.
