Making a collimator scope


We present to your attention the idea of ​​making a collimator sight. The idea will be especially useful for those who are engaged in the independent manufacture of weapons homemade and wants to modify them.

We suggest starting with watching the author’s video



So we need:
- a piece of PVC pipe;
- laser pointer;
- stationery knife;
- a transparent cover;
- scissors.

The first step is to cut a strip from the lid so that it easily passes into the pipe.

Now we heat the clerical knife and make a hole in the pipe so that a strip passes through it, which was cut from the lid at the last step.


We make the same hole on the other hand, so that our strip fits in both holes, forming an angle of 45 degrees.


The next step is to disassemble the laser pointer and cut off the upper part, which is a battery compartment.

We fasten the batteries with tape so that they do not scatter.

We take the wire and twist it from one end, thus creating a contact for the batteries.

We assemble the laser by fixing the batteries and the wire with tape.

In the middle of the pipe we make a hole for the laser pointer.

Since the laser pointer shines very brightly, the author of the idea advises to seal it with tape and paint over with a black marker.

We install the laser pointer in the hole that we made for it, securing it with tape.

If you want the scope to work all the time, you just need to hold down the laser button.

You can proceed to painting the sight, but before that we glue the edges with masking tape. You can paint the sight with spray paint.

Note that this is just an example of how you can independently produce a collimator sight. It can be significantly modernized and improved. To make it more convenient to attach the sight to a makeshift weapons, you can use a plastic mount for PVC pipes of the appropriate diameter.

To be completely accurate, then a collimator is a device for producing a beam of collinear or parallel rays (light in this case).
In the simplest case, a point source of light is placed in the focus of the lens, or concave mirror.
(In practice, it is almost impossible to achieve perfect parallelism of the beam using real lenses and light sources, but for most applications, this is not essential).
In the case of hand gun sights, two collimators were originally used.
We will conditionally call them "blind" and "through."
The “blind” forms the projection of the aiming mark, and for aiming it requires using the effect of binocular vision to combine the image of the mark that one eye sees and the target that the other sees.
"Through" allows you to aim with one eye.
Initially, in such sights, a differently formed mark was used, illuminated by various light sources and placed either in the focus of the lens and then reflected in a plane-parallel plate along the axis of the sight, or in the focus of a translucent concave mirror.
Modern varieties of collimator sights for the same purposes use holographic plates, which simultaneously create an image of the aiming mark, and properly form a light beam.

So the scope you are talking about is modern, advanced
version of collimator sights, and the version that is proposed in the article, the version is very primitive (with all its shortcomings).
This is not a collimator scope. A collimator sight is a kind of holographic sights that projects an aiming mark onto the retina of the eye, as a result of which the aiming point is projected at a distance of 100-300 meters from the sight point. That is, the mark ALWAYS shows at the point of impact and it MOVES relative to the sight when the angle changes.
And here is just a luminous point, no more. It is impossible and useless to aim through such a thing.
