This article introduces the wavelength ranges of near infrared, mid infrared, and far infrared. Various domestic and foreign institutions have given a variety of slightly
A straight line light spot refers to a straight line light spot generated by laser passing through different optical elements. It is often widely used
Chalcogenide spheres are spherical optical elements made of chalcogenide glass. Chalcogenide glass is an oxygen-free glass mainly composed of sulfur, selenium, tellurium and other elements.
Both spherical reflectors and parabolic reflectors are optical elements that use the principle of reflection to change the direction of light propagation. The following is
A mirror with a parabolic reflective surface.If a “point light source” is placed at its focus, the light will be reflected by the mirror and
Dichroic mirrors, also known as two-color mirrors, play an important and irreplaceable role in the field of laser technology. The technology can be traced back
The focusing lens belongs to the gradient refractive index lens. It has the characteristics of end-face focusing and imaging, as well as its cylindrical appearance,
Comprehensive ophthalmometer is an indispensable device in modern optometry examination. Its core function relies on the combination and coordinated work of multiple optical lenses. These
Traffic flow monitoring is an important part of modern intelligent transportation systems, which aims to obtain real-time information about vehicles and pedestrians on the road
High-frequency lasers (such as ultraviolet lasers, femtosecond lasers, etc.) have extremely high peak power and energy density. As common windows for these lasers, optical lenses
