What is the difference between an efficient centerless cylindrical grinder and an ordinary cylindrical grinder? Centerless cylindrical grinding It does not have a head frame and tailstock, but the workpiece and the guide wheel support the workpiece, grinding with a grinding wheel. Unintentional grinding method It is composed of three mechanisms: grinding wheel, adjusting wheel and workpiece support. The grinding wheel actually works as grinding. The adjusting wheel controls the rotation of the workpiece and t
How much do you know about the classification of optical glass?
Optical Classification 1. Colorless optical glass There are specific requirements for optical constants, such as high visible light transmission and no selective absorption coloration. According to the size of Abbe number, it is divided into enamel and flint glass. The types are classified into several types according to the refractive index, and are arranged in order of refractive index. It is used as a lens, prism, mirror, etc. for telescopes, microscopes, cameras, etc. 2. Anti-irradiation optical glass
Optical fog lens concept,new application of optical lens
At present, in China's large-scale surveillance camera project areas, natural conditions such as rain, steam, haze and other natural conditions easily lead to ambiguity in monitoring, and even in severe cases, there is only a white mist. The fog problem has become a weakness of monitoring equipment. However, in the special monitoring projects, it is very necessary to solve the fog problem, so the current monitoring project puts forward new requirements for the fogging technology. At present, the way in which monitoring equipment realizes fogging can be rough
Bandpass filter can well suppress noise test
The purpose of engine knock sensors is to improve engine efficiency and performance by monitoring engine vibration. The engine control unit (ECU) uses this data to adjust the fuel air ratio to reduce the "engine crash" and correct engine timing. TI's TPIC8101 can be used as a signal conditioner for such engine knock sensors. Newer solutions sometimes integrate this functionality into an MCU in an engine ECU, but this means that the process may be done more remotely (because of the lower temperature rating of the microcontroller), which may cause signals Deterioration. The TPIC8101's perf
Difference between normal lens and infrared lens
[ Pacific Security Network News ] Many friends are wondering about this question: Why do the same focal length lenses also divide the ordinary lens and infrared lens? What is the difference between a normal lens and an infrared lens? Next, we will briefly explain the difference between the two:
What is the difference between narrow bandpass filters and bandpass filters ?
There may be a lot of things that are not very familiar to the optical industry. It should be very curious what is the difference between narrow-band filters and band-pass filters? So everyone will have some questions. What is the difference between the two? Bandpass filters allow optical signals to pass through in certain bands, while optical signals that are off-band from this band are blocked. The passbands of bandpass filters are relatively wide, generally half. The bandwidth is above 40nm! The narrowban
Production process of optical glass lens cleaning
It is well known that the optical glass lens processing industry is a very demanding industry, and the standards of the production workshop or the production process must be controlled (for example, all personnel in the clean room must wear white clean clothes, etc.), and There is also a strict process in the cleaning with optical glass cleaner. Only by strictly controlling the production process and allowing the workers to strictly follow the requirements, can we control the quality of the optical glass produced and processed, so what needs to be done in daily production?
optical spherical lens physical parameters
The general industrial lens does not have the magnification factor because the general industrial lens has a different magnification when used at different working distances. At this time, we need to calculate the focal length (f) of the lens and the working distance (WD) of the lens. . 1.1 Magnification (X) The magnification X of the optics is used to describe the ratio of the image size (h') to the object size (h): X=h'/h Generally when imaging with a camera with an industrial camera, the image size is the
scientists used 3D printing technology to create the world's smallest optical lens
A few days ago, scientists used 3D printing technology to create the world's smallest optical lens. The 3D printing lens is only as large as the diameter of two hairs. The microscopic device is said to allow spies to create surveillance cameras that are not as large as a salt. With this technology, spies and police can spread millions of such devices throughout the city, they a
What is a nonlinear optical crystal?
What is a nonlinear optical crystal? The nonlinear optical crystal is the crystal which shows the nonlinear optical effect more than quadratic to the laser strong electric field. Nonlinear optical crystal is a kind of functional material, in which the frequency doubling (or "frequency conversion") crystal can be used to convert the laser wavelength, so as to extend the tunable range of the laser, which has important application value in the fi
Brief Introduction about Optical Aspherical lens
Spherical lens and aspherical lens A Sphere optical lens has a constant curvature from the center of the element to the edge, and the surface is spherical;In contrast, an
Optical glass concave mirror and convex mirrors
Before introducing the difference between the imaging properties of concave mirrors and convex mirrors, the concepts of concave mirrors and convex mirrors are known. Concave mirrors are reflection imaging. A mirror (including a convex mirror) is not an instrument that transmits light but is reflected back to the image, and the light follows the law of reflection. This type of mirror is called "convergence" because they tend to collect the light that strikes the surface, and the parallel incident light will be re-aggregated at the focus, also because the no

Handling and cleaning IR Optics
IR Optics Handling & Cleaning Great care should be taken when handling infrared optics. Please note the following precautions: •Always wear powder-free finger cots or rubber/latex gloves when handling optics. Dirt and oil from the skin can severely contaminate optics, causing a major degradation in perform
