This
new product is a simple, fast yet accurate way of testing Laser Beams for
Collimation
and is available now from Scientific Products. This fine instrument is a
precision testing tool used to check the collimation of laser beams, from the
most complex system to a simple lens. It
is used with lasers, laser diodes and collimated optical assemblies within the
UV-Visible-IR spectral range. The best part is that it is not very expensive.
The output beam sizes are from 3 mm to 50 mm for standard models and the
larger sizes are by special order.
The
way it works is: simply position
the collimation LBCT-tester in the path of a laser beam, rotate it approximately
45 degrees, to direct the beam perpendicular to the output laser beam, as shown
in the photo layout. Then observe
the interference pattern projected on a white card, screen or CCD camera monitor
setup. When the output fringes are
oriented parallel to the reference line of the
LBCT-tester the laser beam is
collimated. That’s all there is to it!
If the fringes are not parallel to the reference line you
may make any adjustments need to reorient the fringes.
This adjustment may be made while viewing the fringes on the screen.
