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...
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...
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...
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....
Basic Knowledge About SWIR Lensens
1. SWIR Lenses is also an optical lensSWIR Lenses refers to the wavelength range between 900nm and 2500nm, which is invisible to the naked eye.Light is an electromagnetic wave. SWIR lenses is located...
What is the Difference Between Spherical and Aspheric Lenses?
1. The difference between spherical and aspheric lenses: surface curvatureThe difference between spherical and aspheric lenses: a spherical lens refers to a constant curvature from the center to the e...
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 ...
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...
