What is an optical lens?
An optical lens is an optical device composed of lenses used to form images on negatives or photosensitive elements. The glass used in optical lenses is not an ordinary material that is only light-transmitting or decorative in our lives. The stability and consistency of its internal parameters are very high, and the prices of materials with different refractive indices are even more than a dozen or so. Ten times the difference, and the so-called “plastics” are high molecular polymers, COC and COP. These materials must be imported from Japan, such as Zeon, Mitsubishi Gas, Osaka Gas, etc.
What are the different types of an optical lenses?
There are three main types of optical lenses: refractive, diffractive, and reflective.
-Refractive optics use a curved lens to bend light; this type of optic is best for imaging because it can focus light very closely.
-Diffractive optics use a series of small diffusers to spread the light; this type of optic is better for imaging than refractive lenses because it can capture more detail at a wider angle.
-Reflective optics use a mirror or other surface to direct the light toward the camera. This type of optic is best for video because it can capture footage in all directions without distortion.
Some advantages of using a lens optic in your surveillance system
When it comes to surveillance, many people think only of cameras. But a camera is just one part of the equation – the other part is the lens. A lens converts an image into a reality on a camera; without it, your surveillance system is useless. Here are some of the advantages of using lens optics in your surveillance system:
– Lens optics allow you to see more detail than a camera can capture. This is especially important in areas with low light or in difficult-to-reach places.
– Lens optics provide higher quality images than cameras with standard lenses. This means that you can find and track targets more easily.
– Lens optics make it easier to keep an eye on large areas – you won’t have to zoom in as much as you would with a camera with standard lenses.
– Lens optics are less likely to be affected by weather conditions than a standard camera lens; they are used in rainy or wet environments without worry.
Optical lenses are mainly used in surveillance, smart home, industry, automobile, etc. If you want more information about optical lenses, please check out the website of YTOT lens.
