The 272-15 is a multiple purpose test collimator, specifically designed for use in collimating test  stands and instrument adjustment applications.  Use it to test the straightness of the line of sight of your optical instruments or as a general purpose infinity collimator.  It has eight filar/bi-filar targets placed at various optically-simulated distances.  Each target contains a label identifying its "distance" along the optical path.  This allows you to test and calculate the deviation of any optical instrument's line of sight from a perfectly straight line.  A special objective system assures high target definition and optical clarity.  Each target is adjustable and may be centered on the mechanical axis of the collimator if desired.  Targets are illuminated using the low-voltage light source (included) for backlighting.  The 272-15 may be mounted in any V-block or wye-type base such as our 88-6 or 89.  Plastic instrument case included.
