Farpoint 650nm Laser Collimator - 1.25 Inch / 2 Inch

The Farpoint 650nm Laser Collimator with 1.25"/2" combo stepped barrel — our most versatile model, fitting both 1.25" and 2" focuser drawtubes with a single tool. Precision-machined in the USA with a lifetime alignment guarantee. Includes carrying case. For Newtonian and Dobsonian reflectors only.

Why This Laser Collimator Is Different

Every Farpoint laser collimator body is machined from a single piece of aluminum in one machining step — not assembled from separate parts — ensuring perfect concentricity from the factory. Our superior eight-screw alignment system locks both ends of the laser diode in place with directly opposing screws, delivering precise and lasting alignment that cheaper three-screw designs can't match.

Key Features

• 0.76mm beam aperture — the smallest of any collimator on the amateur astronomy market, producing less speckling and dramatically more precise readings on your primary mirror
• Extra-bright 650nm red laser for clear visibility in all conditions
• 1.25" / 2" combo stepped barrel — one tool for any Newtonian in your collection
• Rugged red anodized body — red finish best shows the position of the laser return beam for easier alignment
• Protected switch with positive action, shielded by an aluminum ring to prevent accidental power cycling
• Includes mirror center-marking template and triangle center spots (standard template works with mirrors up to 12.5" — large templates available separately)
• Carrying case — keeps your collimator protected in transit

The First Step in the Two-Tool Workflow

A laser collimator gives you an accurate secondary mirror alignment and gets your primary into the ballpark quickly — the essential first step. For final, precise primary mirror alignment, pair this laser with a Farpoint Cheshire eyepiece. This two-tool approach is widely regarded as the gold standard for Newtonian collimation.

Want both tools in one package? Our 2" Collimation Kit bundles this laser with a Cheshire and center-marking kit in a padded carrying case. For the most demanding setups, our 2" Super Kit adds an autocollimator for iterative refinement.
