HoTech - 2"/1.25" SCA Laser Collimator - SCA-2D

Built-in Self Centering Adapter
No more loose fitting laser collimators! Our patented Self-Centering Adapter cleverly eliminates the slop problem by using expanding rubber rings. As the rings expand, each ring fills the focuser slop and center positions the laser collimator in the drawtube. The SCA mechanism accommodates most brands of focusers allowing repeatable installation for an accurate collimation.

High Accuracy Laser Alignment
We position the laser precisely in the exact optical path and align the pointing of the laser beam parallel to the optical axis. It is critical to keep the laser beam centered along the optical path for an accurate collimation, otherwise collimating with an off-axis laser beam will introduce astigmatism into your telescope.

Includes 45¼ Faceplate Viewer w/ Laser Engraved Targeting Grid
The faceplate viewer helps to display the returning laser with a clear visual reference during collimation adjustment. The faceplate allows you to align your primary mirror from the rear of the telescope eliminating traveling to the front of your scope repeatedly during collimation. HOTECH understands the importance of this, so the faceplate is a standard feature in our SCA Laser Collimator. In addition, the faceplate pattern is beautifully laser engraved for an excellent target view.

Fine Projecting Laser Dot
Keeping the laser dot to the finest point is the key to precision collimation. We limit our laser beam to the finest size to operate in the correct distance for optimal visual effect. There is no guess work involved like other laser collimators which is difficult to center a large projecting laser dot to the center of the faceplate. Our understanding and experiences of the laser design permit you to have an effective and precision laser collimator.

New Crosshair Laser Collimator Model Available
No more guess work during the final primary mirror collimation! The crosshair laser easily guides you for a precise final collimation. The extension crosshair helps you to center the returning laser when its center dot disappear into the laser exiting hole. The crosshair also makes centering the dot on the primary mirror donut an easy task during the secondary mirror collimation.

Precision Machined Compact Lightweight
HOTECH engineers successfully cut the unnecessary weight on the laser collimator because we understand that additional weight on a telescope will create imbalance and structure sagging. The lightweight design on our SCA Laser Collimator makes you gain reliable precision collimation. And of course, our laser collimator is CNC machined with the tightest tolerances. So nothing has been sacrificed while you get a stat-of-the-art laser collimation instrument.
