How to Focus & Correctly Calibrate Your Night Vision Scope for Your Eyes

Night vision scope has become very popular in recent years with the swift development of night vision technology.

In the near past, it was considered to be a military gear only and very few civilian could purchase such device. With the increase of its accessibility, it is no more the sole property of the army personnel.

Nowadays, we can see that a large number of people are using the scope for camping, hunting, sightseeing, biking or even fishing.

Besides recreational activity, it is widely being used for professional purposes in many disciplines. It is now a primary choice of gear for the professional shooters and the naturalists.

How Does a Night Vision Scope Work?

You might be wondering, how such a device works.

Well, the scope works with an intensifier tube that gathers the photons from the light and turns them into electrons. Then, the electrons are being amplified and converted back to photons. The device then shoots them to a phosphor screen.

Since the mechanism is complex, it may take some time to focus such a device correctly.

We will illustrate below a simple, step-by-step procedure of focusing your scope.

  1. The first thing to do is to set-up the device for night time use. Take the device in a very dark place and remove the objective lens. You should also detach the front lens cap.
  2. Connect the battery to the device and turn it on by rotating the operation switch in a clockwise motion. You are likely to see a green operation light if the device turns on correctly.
  3. Now, wheel the adjustment ring until you can see a sharp reticle in the display.
  4. Adjust the intensity by rotating the operation switch. Clockwise rotation will increase the brightness and vice versa.
  5. Aim at an object and adjust the viewing distance by turning the focus knob. Gradually rotate the diopter ring until your target becomes clear.

Beginners always complain that they can’t focus correctly with a night vision scope. Sightseeing is a little bit difficult for multiple reasons. As you are focusing at night, it is difficult to know whether you are hitting a target or not.

So follow these simple advices for calibrating with a night vision scope.

  1. Turn the device ON and adjust the diopter. Most scopes can focus in both long and short range. So, synchronize the viewing distance of your scope with the target.
  2. If you look at the eyepiece, you will find two intersecting lines in the form of a crosshair. It is called a reticle.
  3. You can fix your scope towards a target and then slowly focus using the focus knob.

  1. Mount the scope on your firearm.

  3. You will see an auxiliary cross sign at the center of the display. Move your reticle using the controller. You have to make sure that the point of impact should be at the center of your target shown in the reticle.
  4. Save the settings and adjust the viewing distance of your scope.

 

Precautions Are Obvious

Necessary precautions need to be taken to protect your scope from damage. You should be careful when you are mounting your scope to a firearm. Adhere to the precautionary guidelines given below.

  1. If you decide to use your night vision scope in daylight then you should put the lens cover on. The lens cover will secure your objective lens on broad daylight. However, you need to put the cover off at night.
  2. Even a small amount of high voltage light can damage your lens. Therefore, precautions should be taken even when you are using this scope at night. Do not focus the scope to a very bright source of light such as fire, projector headlight etc.
  3. If your riflescope has a built-in infrared illuminator installed, you can turn it on by clicking the IR button. However, do not turn it on if you are not in an extremely dark location. You cannot focus the scope after turning on the illuminator.
  4. If the scope doesn’t have eye relief feature, it may damage your eyes on long use. Moreover, the firearm recoils after every shoot. Thereby watch out for the recoil, so that you do not have to injure your eyes.
  5. Tighten the screws after every round of firing.
  6. You shouldn’t mount the scope in a firearm that is loaded with bullets. Mount the scope safely and then load the firearm.
