Most night vision retailers in Canada (and worldwide) essentially eyeball their way through this step using various DIY methods. This results in collimation that is serviceable but far from perfect. We demand perfection and so should our customers and the wider night vision community. There are a lot of retailers that sell night vision but very few that actually build their systems in-house or own proper test equipment. Unfortunately without these tools or an in-house quality control process, there is no way to verify perfect collimation, and calibrated diopter, amongst other things. All night vision is not built equally. Don't live with "good enough". Screen the retailers you are thinking of buying from and ask them about their build process and tools. Demand more.

A shade is achieved by adding black to any pure hue, while a tint is created by mixing white to any pure color. In this example, #010202 is the darkest color, while #f3f9f9 is the lightest one.

The second photo is after it has been properly collimated. The white cross hair sits perfectly in the middle of the black square - this is perfect collimation. The problem is that while it's obvious looking at a two-dimensional photo on a screen, this is not obvious when looking through the goggle as your brain may naturally try to correct for this.

Believe it or not, binocular night vision housings come with optical pods that often do not line up perfectly. Collimation is the practice of aligning the two independent optical axes of each pod so they both point exactly straight in three dimensional space. Why is this important? When using a pair of goggles that are not properly collimated, the human eye and brain tries to correct the misalignment by either crossing your eyes subconsciously, or your brain has to work harder to mentally align the two images. Over time this can become tiresome and can result in fast fatigue compared to a properly calibrated set of goggles. Pictured are some through-tube photos of a binocular device on our Hoffman collimation bridge. How the collimation bridge works is that the goggle sits on a very precise location on the Hoffman test set and two distinct reticles are presented to each optical pod (you can actually see what each reticle looks like in the first photo). Then the bridge is installed over top of the goggle in a precise location and prisms essentially merge the images together into one eyepiece. This is very difficult to achieve without a proper test set or a custom-built precision collimation rig.This device was not assembled by us and it looks like it was collimated using one of the DIY methods. The first photo is how it was received, notice that you are essentially seeing double. Your brain will naturally try to correct for this and cross your eyes.
