The Difference Between Aspherical Lens and Spherical LensA sphere uses one curvature on the whole surface, just like cutting from a sphere. A non-sphere has different curvatures such as cutting from an ellipse. The main purpose of non-spherical is to solve ...view
What Are the Characteristics of Fisheye Camera Lens?Ⅰ. What is a fisheye camera lens?A fisheye camera lens is a special type of ultra-wide-angle lens. It is small and super wide, showing a distorted spherical world view, most obvious in the curved out...view
Introduction of Aspherical Achromatic LensⅠ. Introduction of achromatic lensOrdinary achromatic lens refers to a lens group that corrects the color difference of light of three wavelengths such as blue, green, and red. Because the focus of t...view
The Principle of Achromatic LensⅠ. Introduction of achromatic lensAchromatic lens refers to an improved camera lens, which can reduce or eliminate the color difference. So that, different colors such as blue, purple, and yellow can...view
Comparing Cylindrical Lenses with Ordinary Spherical LensesⅠ. What is a cylindrical lens?Cylindrical lens is generally used to focus incident light on the line or change the image's aspect ratio. It can form a linear image, and the direction of the beam ...view
