Changchun Long Ze Precision Optics Co., Ltd.

As a  Silicon Domes Manufacturer , let's analyze the optical glass processing technology and development direction. According to the development law of optical glass itself and the actual needs of society, we should focus on the following aspects in the future: 1. Improve and develop colorless optical glass Continue to improve and develop LaK, LaF optical glass, thermo-optic stable brand and flint optical glass series; development of variable refractive index glass and optical components; exploration of water-containing glass and its applications. 2. Research and development of laser technology glass of a specific nature Development of low-F laser glass for high-power laser systems, such as fluoride glass; research on phosphate-based, improving quantum efficiency, reducing loss and obtaining repetitive laser glass for laser processing, ranging, etc.; In the inorganic glass, visible and tunable laser glass and laser system are produced. 3. Research glass for microelectron

With the development of science and technology, develop natural resources have been a high speed on land, but many natural resources cannot be regenerated. Ocean resources are vital to us, becasue 71% of the earth's surface is covered in water, most of natural resources at extreme pressures and did not inhopitable for humans. The Rov systems is very important in the development of ocean resources. Optical Dome  is a important parts in the rov system, it is made from optical glass, such as N-BK7, H-K9L, Fused silicon which is by far the superior material for high-pressure environments. Submersible Domes   are the ideal structural shape for strength, it far exceeds the pressure resistance of the flat windows. CLZ optics suggestions for Underwater Dome   system: 1. The smaller the deviation Circularity and sphericity can make the optical dome stronger. 2. Knoop hardness bigger, the dome will be more stronger. The most cost-effective is H-K9L from CDGM or N-BK7 from Schott.

As a  Silicon Domes Manufacturer , let's introduce the processing methods of optical parts. Optical processing can be divided into thermal processing and cold processing. Cold working is the sawing, rough grinding, fine grinding, polishing and centering of the parts. Today, we are going to share with you the related technologies and methods of centering and edging of optical parts processing. The centering of the optical parts is determined by the fact that, for circular optical parts, the size of the side cylindrical surface meets the assembly requirements; for a spherical lens, the alignment of the two spheres (optical axis) and the axis of external symmetry (geometric axis) Deviation (center deviation c: cross center deviation and parallel center deviation). Optical part processing lens centering method: optical centering method (surface reflection like centering method, projection image centering method, spherical center reflection image centering method), mechanical cen

Sapphire is an ideal choice for the transparent dome element in higher speed missile systems due to its high transmission, higher durability, and thermal shock resistance.  Sapphire Domes  for various missile systems are being produced but fabrication technology development is required for cost reduction and improved performance. Major costs of  Optical Dome  production are in fabrication. It has been shown that grinding to near-finished size is important to reduce fabrication costs and improve quality of finished domes. With this approach, optical distortion problems related to the anisotropic properties and subsurface damage can be minimized. Subsurface damage has been shown to reduce sapphire's strength. The depth of subsurface damage has been quantified and it has been shown that room temperature strength can be increased with a post-polish heat treatment. However, the extremely high hardness and brittleness of sapphire make it difficult to obtain defect-free surfaces. T

Optical Mirrors CLZ Precision Optics provide Precision Grade Optical Mirrors , the optical mirror various substrates including N-BK7, low expansion borosilicate glass or fused silica. The polishing can be meet λ/10. We can manufacturing a variety of reflective coatings from custom optical coatings  available upon request. And we can provide custom made holes on an optical mirrors to meet your requirements, we can do machined hole with no cracks on the inner edge of the hole.

IR Optical Components HRFZ- Silicon Hyper Hemispherical lenses , Silicon Lenses CLZ Optics manufacturing optical lenses , except optical glass lenses , we can produces Silicon lenses, sapphire lenses, fused silica lenses. They are a good choice for Infrared optics and Ultraviolet optics. Silicon Optical Lenses , The single crystal of silicon used in semiconductor has low absorption in the infrared wavelength of 1.2 - 7μm and it can be used as an optical element of infrared light.  Sapphire Optical Lenses , Sapphire Optical Components are used in a variety of applications requiring high durability or broad spectral ranges, Sapphire, which is the second hardest crystal, features a variety of attributes that are ideal for use in harsh environments, including extreme surface hardness, high thermal conductivity, high dielectric constant, as well as a strong resistance to a variety of chemical acids or alkalis. For UV light transmission, sapphire is the best material next to UV-grade

Custom Domes Protective Small Housing CLZ optics has successfully made a small Optical lenses  according to customized drawings. The outer radius 8.128mm, inner radius 6.858mm.The dome made by UV Fused silica  Windows , it has a good transmittance from 180nm to2650nm. It can provide good protection for small precision instruments and protection of electronic sensor systems from harsh liquid and gas environments is essential. Optical domes  are lenses with two concentric spherical surfaces. Sometimes they are being referred to as bent plan parallel plates. Consequently it is customary to define parallelism between two surfaces as the maximum thickness variation between the two surfaces. In perfect domes the convex radius is equal to the sum of the dome thickness and concave radius.
