"SKWOPTICS new type optical RED DOT sight" is a new type of easy to see sight controlled by polymer photoelectric imaging microelectronics.

It has a large field of view, day / night, fast aim, suitable for all kinds of firearms with 1913 rail connection seat at all levels.

It is especially suitable for aiming at targets around 100 meters.

It can see through 1moa aiming point and a 68moa aiming ring at the target .

(1) The enemy's light leakage rate is extremely low. Greatly improve the concealment of the shooter.

(2) High aiming accuracy. The aiming ring is basically immovable and the parallax is very small.

(3) The field of view of the window is clean and bright, and the aiming ring is clear, continuous and sharp, without any secondary image.

(4) It can work  with a night vision .

This Red Dot Sight based on "Beam Splitter" principle

 

This structure originated from the HUD on the aircraft and was used in air combat during World War I and World War II.It is still used by a large number of aircraft for aiming.

 

 

The following figure is the schematic diagram of the head up display（HUD) of the fighter:

The above figure is too complicated. We simplify it. The following figure shows us it how to working :

The  Ture HDU Sight On Fighterf：

Its biggest feature is that compared with the general Reflective HUD Red Dot, the parallax is smaller, which is nearly the holographic sight, so the accuracy is very high,while its price is very cheap.

Because it uses that all light rays are parallel. It uses a convex lens to turn the cone-shaped light source into parallel light, and then uses a flat beam splitter to refract, so as to ensure that the line of sight is nearly parallel when it reaches the eyes of shooter.

 

 

The following figure shows the HDU Red Dot, which differs from the traditional Reflective Red Dot in working principle:

 

As can be seen in the figure, the rays of the former are parallel; The light of the latter is divergent, and the divergent light will seriously affect the aiming accuracy.

How does HDU RED DOT work :

The SKWOPTICS HUD Red Dot is composed of the following 3 parts:

an LED light source, a Convex Lens group, and a Glued bak4 prism.

LED light Source：

responsible for emitting strong light; The light is cone-shaped and scattered.

Convex Lens Group:

Change the cone-shaped light into a parallel light.

Glued Prism:

the glued prism is made of bak4 material and bonded by two pieces of glass with glue. There is an inclined beam splitter in the prism.

Working principle:

after the light is emitted from the LED light source, the conical light is changed into parallel light by the convex mirror group.

After the parallel light is emitted, it is refracted in a group of glued prisms, and the light changes direction again, becoming parallel light, entering the human eye, forming a correct aiming state.

The biggest advantage of this red dot structure is that the parallax of the aiming mark is very small, the deformation of the pattern is also very small, and the aiming pattern with BDC function can be produced. This is incomparable to ordinary red dot sight.
