Frequently Asked Questions
- Q: What is night vision for the optical telescopes?
-
A:Night vision is the ability to see in low light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range.
Night vision technologies can be broadly divided into three main categories: image intensification, active illumination and thermal imaging. The Optical telescopes use the principle of Image intensification to achieve the function of night vision.
Image intensification magnifies the amount of received photons from various natural sources such as starlight or moonlight. Therefore, under low-light conditions, through the optical telescope we can only see the fuzzy image, except for the stars. We call it "Low Light Night Vision".
- Q: What Do the Numbers on the Binoculars Mean?
-
A:Binoculars are identified by 2 numbers. The first number is their magnification (or zoom/power) and the second number is the diameter of their lenses. For example, 10×50 binoculars will have 10x magnification and 50 mm objective lenses.
A magnification power of 10 means that an object will appear 10 times closer than it would to your unassisted eye. For example, if you view a deer that stands 1000m away from you through 10x binoculars, it will appear as though it were 100m away (1000 divided by 10).
- Q: What is the Best Lens Size?
-
A:Binoculars with larger lenses (40mm to 50mm) can gather more light and therefore produce brighter images. They work better in low light settings such as dawn, dusk, fog, rain etc. Compact binoculars have smaller lenses which gather less light. They are much lighter and portable and therefore suitable for hiking, mobile use or when you need to travel light.
- Q: What is the Field of view ?
-
A:This spec tells you the width of the area that you can view at a glance, 1,000m from where you stand. For example，if the Field of view is 122m/1000m,What you see is shown in the following picture:
- Q: What is the BAK4 Prism?
-
A:BAK4 is a material with a higher refractive index than BK7. It can effectively avoid vignetting, reduce astigmatism and ghosting, enhance light transmittance, and make the image color more vivid. It is often used in high-end telescopes. BK7 is called general optical glass, and dark edges are usually formed around the imaging, so that the brightness of the image is lost, and the color reproduction is also significantly impaired.
- Q: What is the Fully multi-coated (FMC) ?
-
A:Multiple coatings on all lens surfaces. Fully multi-coated lenses are typical of high-end optics. The objective lens is made of the Fully multi-coated (FMC), which will make the color reproduction balance and can control the glare and ghosting of the picture well. Even in the background of backlight, you can clearly see the picture in the shadow.
