These scales are used with our optical instruments to measure the
precise distance of any object from the line of sight.
Then, since the line of sight is very straight, alignments
between different objects (such as machine components,
foundations, rollers, etc.) are quantifiable.
Our scales have optical targets evenly spaced every 2 mm. The
optical micrometer on an
instrument works like a vernier, displacing the line of sight
laterally. Using this displacement, the reticle is
"brought into register" with the nearest target on the scale,
and the precise displacement is read directly from the
graduated micrometer drum. By adding or subtracting the
micrometer's reading from the scale position, a precise
measurement is made. To learn more about how to measure
using scales and micrometers, look at the
Learning Center on this website.
More information is also available on this website regarding the patterns,
features, and targeting characteristics that we use - see
"About Our Scales".
All of our metric scales are graduated throughout their stated
length (see image at left). Each scale is shipped in a vinyl
sheath.
A number of accessories are available for use with our scales
(listed at the bottom of
this page). These include magnetic holders, levels, and
special adapters. Also included is our line of Invar
extension tubing, available in many different configurations
to suit your measurement needs.
The table below gives you the model numbers and lengths of our
standard metric scales.
