Is a Aspherical Camera Lens Better than a Spherical Lens?
The asphericWhen it comes to the lens, you have to mention the aspherical lens. In many people's understanding, the aspherical lens is a symbol of high level, and the advanced lens is almost all asphe...
Pinciple Revelation of Water Dome Lens Hood
Before 1960s, all of the photos from water are through plane, that is to say opening a port on waterproof case for shooting( that is why lens case in English is called “port”). When we use a micro-l...
Round Concave Mirriors
Round concave mirrors are catoptric imaging. Mirrors( including convex) are reflecting back for imaging rather than get through the light, ray of light follows the law of reflection, that is what we c...
Grasping the Deformation and Use Skill of Lens of the Camera
People have found that image will be out of shape when we use wide-angle lens, which is harldy seen in a medium telephoto lens, that is why many people think wide-angle will make photo out of shape wh...
The Benefit of Aspheric Lens-Spherical Aberration Correction
The most significant advantage of aspheric lens is that it can correct spherical aberration. Spherical aberration is caused by focusing or aligning light with a spherical surface. Therefore, in other ...
The Advantage Application of Fresnel Lens in LED Projection Lamp
Usually, the Fresnel lens is cut into a spherical surface shape in order to minimize the optical aberration of the image during imaging. The lens can better align an ideal point light source into a pa...
5 Ways to Use Fisheye Camera Lenses
With fisheye camera lenses, it is very easy to take creative photos. Fisheye camera lenses are usually not very expensive and can shoot very wide scenes. It is important to understand the fisheye lens...
How Much Do You Know about the Telecentric Lens Application?
1. Application advantages of telecentric lensOne of the important advantages of telecentric lenses is that changes in object distance do not affect the magnification of the image. The telecentric lens...
The Functions of a Fisheye Camera Lens
1. Introduction to fisheye camera lensFisheye lens is an extreme wide-angle lens, and "fisheye camera lens" is its common name. In order to maximize the photographic angle of view, the front...
