Use Anamorphic Lenses in the Digital Age
An anamorphic lens is a special tool that affects how the image is projected onto the camera sensor. They were originally created to allow a wider aspect ratio to be adapted to standard film images, b...
Where Do Fisheye Lenses Work Best?
Because of the creation of unusual images, fisheye lenses are often unfairly regarded as special effects lenses. However, due to the curvilinear way of the fisheye on the periphery, using it in the ri...
Difference Between Fixed Focal Length Lens and Zoom Lens
The zoom lens is a camera lens that can change the focal length within a specific range to obtain different field angles, images of different sizes and different scene ranges. The most prominent featu...
Aspherical Lenses and Cylindrical Lenses
Ⅰ. Understand aspheric lensThe aspheric lens has a better radius of curvature and can maintain good aberration correction to obtain the required performance. The application of aspheric lenses brings...
How to Use Cylindrical Lens?
Ⅰ. Introduction of the cylindrical lensIn most cases, the cylindrical lens is made of cylindrical glass, where the cylindrical surface of the cylindrical lens is a precision-treated (curved) optical ...
Comparing Cylindrical Lenses with Ordinary Spherical Lenses
Ⅰ. 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 ...
The Principle of Achromatic Lens
Ⅰ. 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...
Introduction of Aspherical Achromatic Lens
Ⅰ. 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...
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...
The Difference Between Aspherical Lens and Spherical Lens
A 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 ...
Do You Know Anything About Achromatic Lenses?
Ⅰ. About Apochromatic LensesAn apochromatic lens is made up of two optical components that are cemented together: a positive low refractive index and a negative high refractive index. In comparison t...
