In the production and application of the filter, it is often encountered that test data of filter product coating is not the same as the measured spectrogram after a few days and the wavelength of the...

Ⅰ. About optical lensesOptical lenses are lenses manufactured by optics. Optical lenses have specific optical properties such as refractive index, dispersion, transmittance, spectral transmittance, a...

Ⅰ. The role of optical mirrorAn optical lens is a visual element made of transparent materials (such as glass, crystal, etc.), which will affect the curvature of the wavefront of light. It is a devic...

The filter is made of plastic or glass and special dyes. The red filter can only let red light pass through, and so on. The refractive index of the glass sheet is initially similar to that of air, and...

What is a cylinder lens? Generally, it is a lens used to focus the incident light on the line or change the aspect ratio of the image. It is usually linear imaging, which can control the direction of ...

The laser beam splitter is abbreviated as the beam splitter, and its similar products also have a diffractive multi-line array DOE. That is, a 1*M line array is obtained instead of a 1*M dot array. Th...

The optical lens should be very familiar to people in the machine vision industry because the lens is an essential part of the machine vision detection system. We should also understand the principle ...

Ⅰ. Advanced measurement and evaluation of precision optical componentsThis paper mainly introduces the detection principle and technology of precision optical components comprehensively and comprehen...
