Explore the Aspheric Achromatic Lenses
The aspherical achromatic lens is a cost-effective lens with excellent chromatic aberration and spherical aberration correction functions, and meets the demanding imaging requirements of today's o...
Imaging Advantages of Apochromatic Lenses
1. Introduction of apochromatic lensAn apochromatic lens is a lens made of two optical components, a positive low refractive index (Crown) and a negative high refractive index (Flint).apochromatic len...
Why Use Penta Prism for SLR Cameras?
People nowadays are very familiar with SLR cameras. SLR cameras are single-lens reflex viewfinder digital cameras. The principle of SLR cameras is to use a single lens to view the view, and the light ...
How to Choose the Projection Lens, Prism and Lens?
1. Classification of projection lensThere are basically two types of projection lenses, one is prism and the other is lens. Prism-type projection lenses are anamorphic lenses composed of one or more p...
What is a Micro Lens Array?
At present, people have been able to make lenses and lens arrays with very small diameters. Such lenses and lens arrays are usually not recognized by the human eye. They can only be observed with micr...
Production Process of Cylindrical Lens
The production process of cylindrical lens mainly includes rough grinding, fine grinding, polishing, centering and edging.1. Rough grinding of cylindrical lensGenerally, the rough grinding of a small ...
What is the Collimation Function of Beam Expander
1. The collimation function of the beam expanderThe beam expander also has a collimating function, but the beam expander is aimed at the beam (beam with a certain divergence angle). Many lasers on the...
What is a Corner Cube Retroreflector
1. What are corner cube retroreflectorsWhat are corner cube retroreflectors? Today, let’s take a brief understanding. The corner cube retroreflector is generally called Paul prism or Pro prism. It is...
What is a Collimator Lens
1. Overview of collimator lensThe collimator lens is for point light sources, and the so-called point light sources, we see more in our lives, such as: match head lighting, old-fashioned flashlight bu...
The Basics of Bandpass Filters
Bandpass filters are used to transmit the required wavelength range and cut off the unwanted wavelength range. Their design is essentially a thin film formed by vacuum deposition technology, which con...
Basic Concepts and Parameters of Optical Filters
1. The basic concept of optical filterAn optical filter is simply an optical device used to selectively filter the required radiation band. The substrates are mostly optical materials such as white gl...
Classifications of Filters
Although there are many types of filters, they all have the same basic function: transmit light of a specific wavelength or color range while preventing the remaining wavelengths from passing through....
How to Judge the Quality of Optical Lenses?
Ⅰ. There is no good or bad optical lensesTheoretically speaking, the optical lenses can only be suitable or not. Generally, the more expensive the optical lenses, the better the image quality. The op...
