1. What is the plane concave lens?Plane concave lens is a negative lens with a negative focal length, and the parallel light beam will diverge after incident on the plane concave lens. The outgoing li...
Dear Sirs,We cordially invite you to visit us at Laser World of Photonics 2022 in Munich, Germany, April 26 - 29, 2022. ECOPTIK is presenting Lens,spherical lens,laser windows,filters etc. as well as ...
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...
