* Single red beam operates at 650nm for night time use.

* Single red beam operates at 635nm for twilight use. * The Howie
Glatter Laser Collimator incorporates a solid state laser diode that
does not fade or change with time and use.

* Factory-aligned to 15 arc-seconds providing 0.1 inch accuracy at a distance of 20 feet,

* The Howie Glatter Laser Collimator is shock resistant to keep its alignment - even when dropped.

* Includes 123A lithium battery, 1mm aperture stop, case, and instructions.

The laser collimator is a tool which enables precise adjustment of
the position and alignment of telescope optics, so as to obtain the best
possible image contrast and resolution. Inside is a solid-state laser
diode, which emits an intense laser beam exactly along the central axis
of the cylindrical collimator body. The beam acts as a "reference line"
from which alignments are made. The most important specification for a
laser collimator is the accuracy and stability of the laser beam
alignment with the cylindrical axis of the collimator body. The
alignment tolerance on a Glatter collimator is fifteen arc seconds for
single beam mode, and one arc minute for the holographic mode. In order
to ensure maintenance of this level of accuracy, each of his collimators
are tested for resistance to shock. Howie Glatter designed them to
withstand a shock equivalent to dropping from eyepiece position on a big
dobsonian, up the ladder, without alteration of laser alignment. Most
other laser collimators cannot withstand this kind of accident without
loss of alignment.

Optional Holographic attachments are available to fit all Howie Glatter lasers.

optional holographic attachments screw into the laser aperture and have
a white screen front surface. They contain an optical element that
diffracts most of the laser light into a diverging symmetrical pattern
around the central beam. The projected pattern is useful for centering
optical elements by making it symmetrical with the edge of the optic.

  •  The most versatile pattern is a 10x10 line square grid pattern of
    illuminated lines. It covers a wider angular range (21 degrees) than any
    other holographic collimator, which allows direct centering of f/ 2.7
    to f/ 35 optics. This pattern is recommended for general use because it
    can be used with the fastest telescopes likely to be encountered. A
    rectilinear grid pattern gives the highest accuracy and sensitivity for
    centering circular optics of arbitrary size.


  • A cross-hair and circle “scope” pattern is available that spans 10 degrees. 


  •  A nine-concentric circle pattern is available that spans 10 degrees and will reach to the edge of f/ 5.7 optics.
