Changchun Long Ze Precision Optics Co., Ltd.

  Surgical operating microscope technology enables doctors to observe fine tissues more clearly. With the operating microscope, doctors discover various lesions and complete various microsurgery operations. Operating microscopes integrate optics, precision machinery and electronic control technology. They are used in neurosurgery, ENT, dentistry, ophthalmology and other fields. The microscope part is the core structure of the surgical microscope. Its optical path system includes an observation system and an illumination system. Observation  O ptical  S ystem The operating microscope is a three-dimensional microscope system. The stereo microscope is designed according to the principle of human stereo vision. Two separate light paths image the object to the left and right eyes of the human. The images are processed by the brain to produce a complete stereo impression. In order to ensure a good stereoscopic effect, the left and right eyes must observe the object at slightly different angl

Because of its excellent physical and chemical properties, fused silica is widely used in electronics, electrical appliances, military, aerospace, optical communications, electric light sources, chemical engineering, metallurgy, instrumentation, optical lenses, anti-corrosion materials and refractory materials. As a Dome Lens Manufacturer, share it with everyone. Fused silica is widely used in high-tech fields: high-purity high-temperature resistant quartz glass tubes, high-purity coated crucibles, quartz glass for optical communications and quartz glass for lasers have all developed rapidly. Fused Silica Mirror (1) Electric light source industry Electric light sources convert electrical energy into light energy and are widely used in daily lighting, industrial and agricultural production, national defense, and scientific research. Common low-intensity energy-saving lamps, germicidal lamps and high-intensity Ley lamps, sodium lamps, metal halide lamps, infrared lamps, and ultraviolet g

The LED car headlights need to be equipped with optical lenses to achieve the effect of condensing light. The light output brightness will not decrease during use. The car light line-cutting star with the lens will not cause the headlight source to scatter, and achieve a good condensing effect. As a   Dome lens Manufacturer , share it with everyone. Glass Optical Domes The addition of optical lenses makes the headlights more reasonable, and unnecessary glare is well controlled. Compared with the addition of lenses and halogen lights to LED headlights, the gap is too large. After all, a candle is a candle, no matter how powerful it is, it will not be too bright. Xenon lamp pretend lens benefits The effect is the same as that of the LED lamp with a lens, but we all know that the road killer high beam, the headlight glare with the lens will not scatter, and the strong light emitted by the LED bulb or xenon bulb will produce strong scattering, which will affect others. The driver is not fr

The laser beam expander improves the working effect of optical instruments by changing the diameter and divergence angle of the laser beam. Its structure is an optical lens group. The optical instrument, which is equipped with a beam expander, is beneficial to reduce loss, bear high-power laser and transmit visible light. The laser beam emitted from the laser has a certain divergence angle. Through the adjustment of the beam expander, the laser beam becomes a collimated (parallel) beam. Then the beam is focused by a focusing lens and into a high-power density spot. The laser beam expander is generally composed of fused silica lenses, K9 lenses, zinc selenide lenses (ZnSe lenses) and germanium lenses (Ge lenses). According to the wavelength of the laser, the laser beam expander can be divided into CO2 laser beam expander for 1060nm, Nd : YAG laser beam expander for 1064nm, 532nm and 355nm, and HeNe laser beam expander collimator 633nm. The laser beam expander usually uses the Galileo t
