What Are Night Vision Binoculars?
Night vision binoculars, sometimes called NHBs, are optical binoculars that have night-vision capabilities. In essence, the optical system on these binocular is designed to provide you with a clear image even at nighttime. So, basically, you're getting the same viewing benefits offered by normal binoculars minus the added advantage of being able to view things up close at night. These binoculars work by using lenses to magnify images and focus them into a smaller scope. They allow users to look into darkened areas that normal cameras and spotting scopes can't illuminating.
There are two major types of night vision available on these devices: monocular and pulsar. The most common and versatile feature is the ability to magnify objects while they're not lighted. The two major technologies behind these are the High and Low Power Levels that offer different benefits. Let's explore how these play a role in providing benefits to individuals.
One type of night vision binocular is called the Thermal Night Vision Binocular. This is made with an infrared heat-sensitive diopters system and includes an adjustable objective lens. These features provide true thermal imaging that's up near the center of the objective lens. This technology allows for you to flip down the screen and see near and far in low light environments, such as a darkened room or airplane hangar.
The other type is called the Photopic Night Vision Binocular. It has a larger objective lens than the Thermal Night Vision Binocular. Because of this, it offers higher resolution image imaging than the Thermal Night Vision Binocular. The Photopic Night Vision Binocular is also designed for greater field of view thanks to its large objective lens. The Night Vision Binocular is best suited for the handheld unit and weighs five ounces.
What are night vision binoculars for people with low light vision? The Thermal Night Vision Binocular is suitable for people who don't need high contrast or high-resolution images. They also work best for everyday use because they are so versatile. The most common application for low light binocular is spotting prey at a distance. This is due to the low light level. This technology enables hunters to watch moving animals at a distance by using low-light imaging.
Night vision goggles are a popular alternative to night vision binoculars. These devices can be worn either on your face or behind your eye. The main benefit to using a pair of night-vision goggles over a pair of binocular is the portability factor. You can easily tuck the goggles into your pocket and take them with you camping, fishing, hiking, and more.
Some binocular designs also include some additional capabilities such as night driving and military binocular models. Night vision binocular enthusiasts use various types of low light and bright illuminations. Some of the popular low-light illuminators include monochromatic illuminators, monochrome illuminators that give color information by emitting a certain color of light (usually green, yellow, or red), and laser illuminators. Military binocular manufacturers also produce night-driving capabilities that incorporate infrared technology. The infrared illuminator gives high contrast and high-resolution images while preserving the low light capability.
Hunters and other outdoor sportsmen are probably the largest market for what are night vision binoculars. Manufacturers have produced a number of different configurations specifically to cater to the needs of hunters. For hunters, there are night vision rifle scopes that are effective at both long-range shots and close-range shots. Other options include cross-country hunting binocular models that provide hunters with a clear image of the terrain they are on so they can get a better idea of their location. This helps them to know where they need to be at a certain time to get a specific animal. For military and law enforcement, night vision optics is a common piece of equipment used for surveillance and target spotting.
