Two orthogonal directions of a cylindrical optical lens define the reference system: the power direction and the non-power direction. The first direction is called the "refractive direction"...
Because achromatic cylindrical lenses focus colors at the same point, they enable users to focus on an image completely. Achromatic cylindrical lenses produce clearer images than uncorrected singlet l...
Ⅰ. UV fused quartz right angle prismIf the uncoated needs higher UV transmittance or lower thermal expansion coefficient, you can choose UV fused quartz right angle prism. UV-grade fused quartz has h...
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 ...
