Protective lenses are very important precision components in the optical path system of laser cutting machines, and their cleanliness has a significant impact on the
Focusing mirror is one of the accessories for optical fiber laser engraving machines, cutting machines, marking machines, welding machines, and other laser equipment. The function
Color filters are also known as “filters.”. An optical glass device that selectively absorbs (or passes through) light according to different wavelengths. An optical color
When wearing glasses, we often need to combine various factors to choose glasses. Spherical and aspherical surfaces are one of the parameters. So what’s the
1. Colorless optical glass: It has special requirements for optical constants, and has high transmittance in the visible light region, without selective absorption and coloring.
Glass has been used in modern times and has always been a product with a large market demand. By using specific processing techniques, we can
What do we mean by a spherical lens? 1、 Basic concepts Definition: A mirror whose reflective surface is a part of a spherical surface is
In optical devices, a piece of glass or other transparent material that is cut at precise angles and planes and can be used to analyze
Optical filters are used to “attenuate or enhance the image.”. Optical filters can also reflect unique wavelengths, dividing images into two identical images or transmitting
Spherical lenses achieve different imaging purposes by changing the spherical radius of the lens, which is difficult to process when the focal length is too
