Can night vision goggles be used during the day? I believe this is a question that most users who will buy night vision goggles are wondering. Let's discuss this issue in detail. Hope it helps you.
There are many kinds of night vision devices, but from the perspective of built-in core components, they can be divided into image-increasing tube night vision devices and digital night vision devices. Infrared night vision devices, low-light night vision devices, etc... The image intensifier tube is used as an image intensifier, but a low-light CCD is used as an image intensifier.
The infrared night vision device is basically composed of an optical system, a video tube or a low-light tube, a power supply and a power supply system. Of course, the active infrared night vision device should also be equipped with an infrared searchlight, of which the image tube or the low-light tube is the "heart" of the night vision device. Image-changing tubes can convert invisible infrared images into visible images, while low-light tubes can enhance weak light by tens of thousands or even hundreds of thousands of times, making it perceptible to the human eye.
Through the above introduction to the infrared night vision device, you must be able to know very clearly, yes, the infrared night vision device, that is, the image-increasing tube night vision device cannot be used normally during the day, because even if it is used, it needs to cover the objective lens. cover. But to be honest, there is no point in using the image-increasing tube night vision device during the day with the cover of the objective lens.
Let's talk about another night vision device, digital night vision device. As mentioned above, this type of night vision device does not use an image intensifier tube as an image intensifier, but a low-light CCD as an image intensifier. The low-light CCD can recognize very low light, and then convert it into a visible digital signal, which is displayed on the LCD screen inside the night vision device. This kind of night vision device can not only be used at night, but also can be used during the day. The images during the day are generally color imaging.
To sum up, the image-increasing tube night vision device cannot be used normally during the day, and the digital night vision device can be used day and night. Choose the right product according to your needs
