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
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 ...view
Aspherical Lenses and Cylindrical LensesⅠ. 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...view
Difference Between Fixed Focal Length Lens and Zoom LensThe 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...view
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...view
Use Anamorphic Lenses in the Digital AgeAn 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...view
How to Maintain Projection Lenses?Ⅰ. The projection lenses need cleaning and maintenanceSince the projection lens is directly exposed to the air, dust will inevitably fall on the surface of the lens. If the dust on the lens is not re...view
