SynopsisThe close-range zoom lens is an optical lens that can change the focal length while keeping the distance between the lens and the object constant, so as to achieve close-range zoom. A close-range zoom lens is usually composed of multiple groups of lenses, and .....
SynopsisA unidirectional spot expander is an optical component used to expand a unidirectional spot into a multi-directional spot. It usually consists of a lens and a prism. The lens is used to focus the light, and the prism is used to disperse the light, so that the .....
SynopsisSilicon aspheric lens is an aspheric lens made of silicon material, usually made of single crystal silicon. Silicon aspheric lenses have many excellent optical properties, such as high refractive index, low dispersion, high thermal stability and chemical stabi.....
SynopsisAspheric achromatic lens is an optical element, which adopts the design principle of aspheric lens and combines the characteristics of dispersion to achieve better imaging quality. Dispersion is the difference in the refractive index of light of different wave.....
SynopsisA slow-axis collimator is an optical component used for fiber alignment to align the slow axis of the fiber (that is, the direction of slower propagation in the fiber) with the optical axis (that is, the direction of faster propagation in the fiber) allow. Slo.....
SynopsisA polarization test piece is a test tool used to detect the state of polarization in an optical system. It is usually made of a piece of material with special optical properties, such as polarizing glass or polarizing film. Polarization test pieces can test th.....
SynopsisA Radial Polarization Converter is an optical component that can convert linearly polarized light to radially polarized light, or convert radially polarized light to linearly polarized light. It is usually made of a crystal with special optical properties, suc.....
SynopsisMid-infrared waveplates are optical components used in optical systems, usually made of crystalline materials, that selectively transmit or block specific wavelengths in the mid-infrared spectral range. Mid-infrared waveplates are commonly used in applications.....
SynopsisThe long-range freight plane is an aircraft designed for carrying cargo over long distances. These aircraft have a larger fuel capacity and range than traditional cargo planes, allowing them to travel further without stopping to refuel. They are essential for .....
SynopsisThe floatplane, also known as a seaplane, is a type of aircraft that is designed to take off and land on water. It is equipped with floats or pontoons instead of wheels, allowing it to operate on water, land, or both. Floatplanes are often used for transportat.....
