Collimator sight - what is it and how does it work?
A collimator is a modern sighting device that is used to align the aiming axis with the axis of the gun barrel or with the axis of the target barrel. This device is based on an electronic circuit and replaces the traditional aiming instruments (musket and sapphire). The collimator is also characterised by its simplicity of use and high efficiency, thanks to which shooting performance can be significantly improved. It is used among others by professional shooters, but also, for example, by airsoft players. In this article, we discuss what exactly a collimator is and how it works, as well as the types of collimator.
How does the collimator sight work and what is it used for?
A collimator sight is an optical device that uses the phenomenon of collimation to operate. This phenomenon consists of collimating the light beam, i.e. directing the light rays in such a way that they move parallel to each other. In collimator sights, the light emitted by the diode is reflected by a specially shaped lens or prism, causing the user to see a bright aiming point (usually a red or green dot), regardless of the position of the eye in relation to the sight. This makes aiming faster and more intuitive, as the eye does not have to be precisely aligned with the aiming line, as is the case with classic optical instruments.
The aiming point visible on the lens can additionally be adjusted both vertically and horizontally. Furthermore, the use of the collimator does not require the alignment of the instruments (the collimator replaces the musket and jaw) or the closing of the eye. The collimator sight is one of the most effective sights at medium and short distances. Allows shots to be fired at distances from a dozen to several hundred metres.
Types of collimators sight
The first collimators were used as early as the 1960s. Since then, they have undergone many changes and several types of these sights have been developed. Collimators can be divided, for example, according to their construction. This division includes open and closed collimators. Each type of collimator will work well, depending on the design, for different activities or for a different type of weapon.
Open collimator sight
An open collimator is a sight characterised by an open design that allows free observation with both eyes. It consists of a lens responsible for collecting light, a projection lens and a light source (for example, an LED).
The advantages of open-design collimators are easy and quick handling, low weight and a wide field of view. These properties are useful in situations that require quick reactions, including dynamic shooting. Was include low resistance to mechanical damage and susceptibility to weather (for example, rain).
Closed collimator sight
The closed collimator resembles a telescope in construction. All the optical elements of the rifle scope are enclosed in a tube. A closed collimator also consists of the objective lens, the projection lens and the LED. The closed design provides better protection against mechanical damage, dust, sand or moisture, so it can be successfully used in bad weather and difficult field conditions. Another advantage is the possibility of using additional optical devices such as magnifying instruments. Closed collimators are often used by soldiers and officers of other uniformed services.
The choice of collimator depends, among other things, on weather and field conditions and the shooter's preferences. If you need a lighter sight and undertake activity in good weather conditions, an open collimator is a good choice. If you need more protection, a closed model is worth choosing.
Holographic collimator sight
A holographic sight is very often referred to as a holographic collimator, although this is not quite the right term.
The holograph is an improved, more modern version of the collimator. The method of operation is very similar to that of a collimator - the light beam is also collimated, but instead of an LED, the device uses a laser. The holographic sight is constructed in an open system.
When using a collimator at long range, there may be a situation where the aiming crosshairs obscure almost the entire field of view. In holographic sights, this defect is eliminated because the crosshair itself is generated in a different way. There is an additional electronic circuit in the holographic sight.
This type of sight is used by sharpshooters and special military units, among others.
Collimators sight on offer at Militaria.pl
It is worth remembering that collimators and holographic sights require power. In the Militaria.pl offer you will find battery-powered models, as well as models with mixed power supply, such as a combination of a solar battery and a traditional battery or a solar battery and a built-in rechargeable battery. The mounting of the optoelectric device should also be taken into account, this can be on a Weaver type rail, 11 mm rail or on a stand.
In the Militaria.pl shop you will find a wide selection of collimators from manufacturers such as Aim-O, Burris, Bushnell, Delta, Optical, Hawke, Holosun, Steiner Optik, Umarex, Vector Optics or Vortex.
