Some novice friends received the binoculars and looked forward to them but didn’t know how to use them. They weren’t adjusted so well that the imaging couldn’t overlap, the field of view was dark, and they couldn’t be adjusted at the same time. Let me introduce how to use the binoculars and pay attention. matter.
First step: spin up the eye mask
Friends who do not wear glasses for observation will turn the eye masks up, and those who wear glasses for observation will turn the eye shields down.
Fold the eye mask:
Friends who don’t wear glasses don’t need to fold it up. Friends who wear glasses fold down the eye mask when observing.
This is to keep the eyes and eyepieces at a proper exit pupil distance. If they are attached too close or too far away, there will be dark shadows in the field of view, and a complete circle of vision cannot be obtained.
In addition, if the eyecup is not turned up when a friend who does not wear glasses observes, the eyelashes are also easily scratched and the eyepiece lens is stained with grease, which affects the sharpness of the image, and the observation will have a foggy image and the image will be blurred.
Step 2: Adjust the interpupillary distance
Many children's shoes say that the telescope always sees two circles, and there is a black shadow in the middle that cannot be overlapped. That is because the interpupillary distance has not been adjusted properly. Operation method: Adjust the distance between the two lens barrels to the same as the pupil distance of your eyes, so that the images can be overlapped.
The interpupillary distance is different for people of different ages. For example, the interpupillary distance of children is relatively small, while the interpupillary distance of adults is relatively larger. Adjust the distance between the two lens barrels to the same as the pupil distance of the eyes, so that the images can be overlapped and observed without shadows.
The third step: focus
Slowly turn the focus wheel to focus and adjust the sharpness!
Add parallax adjustment:
Some people have different degrees of two eyes, such as 100 degrees for the left eye and 300 degrees for the right eye. After taking off the glasses, you will find that both eyes cannot see clearly at the same time. This is because the eyes have parallax. At this time, you can first turn the middle focusing wheel to make the left eye clear, and then slowly turn the right eyepiece or fine-tune the parallax compensation, and both eyes can observe a clear image at the same time. The same person's parallax adjustment only needs to be adjusted once. After adjustment, you only need to turn the middle focusing wheel to focus.
Some novice children's shoes received the telescope because they were not familiar with it, they turned it to the end when they saw that the right eyepiece or the parallax ring could be turned. But if the vision in both eyes is normal and the parallax is turned to the end, no matter how you turn the focus wheel to focus, one side will always be blurred, and a clear image cannot be obtained at the same time. So everyone should pay attention to this. Generally, if the parallax ring can be seen clearly at the same time, don't move or screw it to the end.
IR Fusion Thermal Binocular
It has the advantages of low light and thermal imaging. They are many observation modes to choose
from, which can better meet the observation needs of different scenes and different people;
• The observed information is more abundant, the details are more perfect, the scene is easier to
understand, and the detection distance is more effectively detected;
• The target of observation is more obvious, which is better for detecting targets faster and more
I believe that after reading the above explanation, you should know how to use the telescope correctly
Simply say a few points for attention:
1. Do not use telescopes to observe the sun directly, as this will cause serious damage to the eyes or even blindness.
2. Don't drop the telescope, avoid vibration and impact, so as to avoid the deviation of the optical axis and make the observation dizzy.
3. Don't touch the lens with your hands to avoid staining the lens with grease, fingerprints, etc., which will affect the clarity of the image.
4. Do not watch the telescope while walking to avoid accidentally stepping on dangerous objects and causing personal injury.
5. Do not put the telescope in a car under the scorching sun or expose it to the sun for a long time to avoid high temperatures to accelerate the aging of the rubber.
6. Non-waterproof telescopes do not need to be kept dry for a long time, which can prevent the lens from growing mildew in a sealed bag with a desiccant.
7. Do not put the desiccant in the telescope in a place where children can get it to avoid injury caused by children swallowing the desiccant.
8. Please cover the objective lens cover and eyepiece cover after using the telescope to prevent dust from falling on the lens
