Changchun Long Ze Precision Optics Co., Ltd.

  As a   Silicon Domes Manufacturer , share with you. Optical glass can change the direction of light propagation. Optical glass is widely used in many modern high-tech industries such as aerospace, information, microelectronics, surveying and mapping with its unique characteristics of high temperature resistance, low expansion coefficient, high mechanical strength, and good chemical properties. Optical glass is widely used in lenses and prisms of optical instruments. Optical glass must meet the requirements of light imaging, so the quality of optical glass is also very high. Glass Optical Domes Qualified optical glass must meet the following requirements: 1. The optical constants of the optical glass and the same batch of glass must be consistent. The optical glass has a specified standard refractive index value for different wavelengths of light, which serves as the basis for the optical designer to design the optical system. Therefore, the optical constants of the optical glass prod

Our  optical domes  are widely used in solar energy measuring instrument, underwater camera and high-pressure window of submersible. It provides long-term protection for measuring instruments in natural and expose d environment. The stability of our material protects the instruments from erosion of natural environment. It can also work at depth of 5000m under the water. Because of the stability of dome, it can greatly protect the proper functioning of underwater camera and provide high light transmittance with a 180 °  field of view, which is one of the most important elements for deep-sea detection. During the last few years, we’ve delivered more than 25,000  dome lenses . Through years of accumulation, we possess many kinds of ready-made tools and stocks sized from 24mm to 125mm. We can ensure  the fastest delivery date, the best quality and the most optimal price whenever you need.

  As  precision   optical components  manufacturer , CLZ optics introduction Optical system of the solar simulator. The solar simulator is test equipment that can simulate the characteristics of real solar radiation. Its optical system has the characteristics of high irradiance, high collimation, high stability, and high radiation uniformity. It is widely used in the photovoltaic field, environmental simulation field, meteorological instrument calibration, agricultural breeding field and space sensitive period calibration field. The optical system of the solar simulator is mainly composed of a light source (xenon arc lamp), a combined condenser system (a combination of an ellipsoidal mirror and a spherical mirror), an optical integrator, a plane reflector, and a collimating objective. 1. Combined condenser system The combined condensing system using an ellipsoidal mirror and a spherical mirror can greatly improve the energy utilization rate of the entire system, which is nearly double

  In physics and optics, the Abbe number, also known as the V-number or constringence of a transparent material, is a measure of the material's dispersion (variation of refractive index with wavelength) in relation to the refractive index, with high values of V indicating low dispersion (low chromatic aberration). It is named after Ernst Abbe (1840–1905), the German physicist who defined it. The Abbe number, V, of a material is defined as V=（nd-1）/（nF-nC） where nd, nF and nC are the refractive indices of the material at the wavelengths of the Fraunhofer d-, F- and C- spectral lines (587.6 nm, 486.1 nm and 656.3 nm respectively).   Abbe numbers are used to classify glass and other optically transparent materials. For example, flint glass has V<50 and crown glass has V>50. Typical values of V range from around 20 for very dense flint glass, around 30 for polycarbonate plastics, and up to 65 for very light crown glass, and up to 85 for fluor-crown glass. Abbe numbers are only a
