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...
Diamond Lens Makes Laser Optical Material Processing System Lighter
Diamond has some remarkable properties: for example, its refractive index is 2.4, which is very high, and can be made into thinner optical components for optical systems with the same optical power. T...
The research of crystal glass with ferroelectric semiconductor photoelectric effect has been develop
The polarized photoelectric crystal glass with non-central symmetric structures are based on the spontaneous polarization, which shows the excellent optical performance of nonlinear optics, piezoelect...
Scientists have Simplified the Terahertz Device by Integrating Lasers and Reflecting Mirrors
An electromagnetic pulse that lasts a millionth of a second could be the key to medical imaging, communications and drug development. But this pulse, known as terahertz, requires complex and expensive...
The research of phosphate deep UV optical crystal materials has been developed
Nonlinear optical crystal is an important material of photoelectric information, which has wide application prospects in information, research, energy, industrial manufacturing and medical and health ...
Application prospect of nanocrystalline materials
Nanocrystalline material is a crystal glass with at least one dimension in nanometer scale in the three-dimensional space scale. Its grain size is about 1-250 nanometers. A notable feature of this mat...
Is a Aspherical Camera Lens Better than a Spherical Lens?
The asphericWhen it comes to the lens, you have to mention the aspherical lens. In many people's understanding, the aspherical lens is a symbol of high level, and the advanced lens is almost all asphe...
The Design and Use of Optical Lenses in Physical Optics Engineering
Any optical lens, whether new or old, we can use the term lens description to distinguish between the number of the lens, the types of glass, mirror surface radius, the thickness of the lens, the di...
New Crystal Glass may Allow Humans to Breathe Underwater like Fish
The core problem of underwater activity of divers is that humans cannot ingest oxygen from water, therefore, it is necessary to carry gas cylinders or to supply gas from the water surface, and the bre...
Chinese and Australian scientists have developed nano optical materials for temperature control
Australian National University recently announced that the school and Nankai University jointly developed a new type of temperature control nano materials. This material has great potential for energy...
