Press-O-Film Replica Tape
Press-O-Film Replica Tape
Press-O-Film provides a simple way to obtain an impression of a
surface for analysis. It consists of a layer of crushable plastic micro
foam affixed to a 50.8 µm (2 mil)
incompressible polyester film. When
compressed against a roughened surface, the
foam collapses and acquires an accurate
impression, or reverse replica, of the surface.
Placing the compressed tape (replica) into the PosiTector RTR
gives a measure of the average maximum peak-to-valley height of
the surface roughness profile. The Gage automatically subtracts
the thickness of the polyester substrate from all measurements.
Press-O-Film is available in Coarse (C) and X-Coarse (XC)
grades to accommodate measurements in different profile ranges.
Optical Grade Press-O-Film Replica Tape
For improved optical resolution and to reduce optical artifacts (see
below tape comparison), this special grade of replica tape is
available for use with the PosiTector RTR-P . It provides higher
quality SDF surface data files than conventional Press-O-Film
replica tape. It is available in both Coarse (C) and X-Coarse (XC).
