DROPimage is a program developed by Dr. Finn Knut Hansen at the University of Oslo and available from ramé-hart instrument co. for measuring contact angles, surface energy, and surface tension. DROPimage was first introduced in the late 1990's and at the time was complimentary to the now defunct RHI program.

DROPimage is currently available in three editions: DROPimage CA for measuring contact angle; DROPimage Standard for contact angle and surface energy analysis; and DROPimage Advanced which is optimized for surface tension and dynamic studies but is also capable of static contact angle and surface energy measurements. DROPimage includes a number of tools for calibration and reporting.
