Telecentric Lenses
In many machine-vision systems, such as those used in semiconductor inspection, precise repeatable measurements must be made consistently. To ensure this occurs, system developers must turn to more ex...
Zoom Lenses
As opposed to a fixed focal length (FFL) lens, Zoom lens focal length can be varied, when maintains its focus. Changing the airspace between the lenses, the lens focal length will change; Such as CCTV...
System Advantages of Aspherical Lenses
Aspherical Lenses allow optical element designers to use less than traditional spherical element to calibrate the aberration, because the former aberration calibration provided for them than the latte...
Basic knowledge of aspheric lens technology
1、Technical principleThe curvature radius of the aspheric lens changes with the center axis. It can be used to improve optical quality, reduce the number of optical components and reduce design costs...
Miniature Lenses
With the rapid growing market of consumer electronics and mobile phones, miniature cameras performance is becoming more challenging compared to years ago. However, manufacturing cost, packaging, imagi...
The market and application of optical materials
In recent ten years, with the development of modern optics, optoelectronics and information technology, there has been a kind of photoelectric digital products and information products with high techn...
The correct way to install optical lenses
In the installation process, if our installation method is incorrect, the optical lenses will be contaminated. Therefore, the previous operating procedures should be complied with. If a large number o...
OCT Lens
Optical Correlation Tomography (OCT) is an imaging technology that has rapidly evolved in the past decade. Leveraging low-coherent light interference, OCT detects the black reflection or several scatt...
Correct cleaning method of optical lens
In the process of installation and cleaning of the lens, any slits, even fingernails or oil droplets, will increase the absorption rate of the lens and reduce the service life. Therefore, the followin...
The Optical System Technology can Realize the Rapid Detection of Pathogen of Septicemia
When treating the blood poisoning, the doctor will immediately take broad-spectrum antibiotic. But the problem is, in most cases, some bacteria have resistance. However, the current analysis of bacter...
How to Effectively Eliminate Spherical Aberration in Optical System Design
Spherical aberration is caused by a sphere on the surface of the lens. The light emitted from the same point on the optical axis converges through the lens at different points in the image field space...
The Design Principles of Infrared Optical System
The infrared optical system refers to the system that works in the infrared band of the optical wave, which is the optical system that receives or sends infrared light waves. In general, the infrared ...
Cleaning and maintenance of optical lenses in laser instruments
With the development of modern industry and the continuous progress of various technologies, we have become more and more demanding of laser technology. The field of laser application is expanding, an...
