Extreme cold weather

Vibrations from mov- ement or expandion and contraction from temperature changes, can cause the mirros to move slightly. SV121 red laser collimator can be used under extremely cold weather of minus -22°F, without affecting the use effect
The sudden temperature difference does not change the spot size, and the spot shape is a dot, instead of the grainy elliptical point

Adjustable collimater

There are 3 collimation sealed screws on the body; if you find it lose collimation , you can use the presentational hex wrench to calibrate the coaxial problem yourself (the calibration hole for most products on the market has been blocked, the user has no way to adjust)

Can fit into 1.25" focusers or diagonals (with removable 2" adapter)

Fits in 1.25" and 2" focusers; SV121 red laser collimator with removable 2" adapter both fit for standard 1.25 inch diameter and 2 inch diameter

Optimized gear adjustment

With "ON-OFF" gear design, only one optimal gear brightness is retained, reducing tedious manual adjustment.In order to obtain an optimal adjustment, it has a side window allowing a disk oriented at 45° with a central hole to be viewed.This can be then later be used to see whether the laser is reflected back on itself, indicating well collimated optics

High quality solid metal body for a long term use
