Please Note:
- This is the "old" version and not the new "NV" version.
- The manufacturer of this item recently changed the thread on the bottom of their collimators. These are referred to as "NV" (new version). The old and new versions are identical except for this thread size
- If you plan to use one of their holographic attachments such as this item, you need to make sure that you match the "old" collimator with the "old" holographic attachment, and the "NV" collimator with the "NV" holographic attachment.
Optional holographic attachments for Howie Glatter laser collimators 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.
A cross-hair and circle “scope” pattern is available that spans 10 degrees. It has utility for non-Barlowed , conventional Newtonian primary collimation, where the primary is adjusted to return the reflected central laser beam back into the laser aperture of the collimator. The cross-hair intersection makes it easier to see when the return beam is centered on the collimator face.
This item is meant for use ONLY with compatible Howie Glatter laser collimators. It cannot be used with collimators from any other brand.
