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.

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 quartz. and sapphire transmission ranges from 0.15 – 5.5μm.

CLZ Precision Optics is an established supplier of precision optical components for university optical laboratory and research departments, we can provides spherical lenses, prisms, windows, Optical Mirrors and wedge windows, with applications for disciplines including particle physics, optical engineering, nanoscience and many more. Many of different institutions well-known university laboratories rely on us to deliver accurate optical components in China. At the same time, we have expanded our business scope and provided our products to more scientific university and research departments worldwide. Most of these organizations require their custom specifications optical components with small batch, many varieties and strict requirements. We have specialized working room to produce small batch, multi varieties products and used our latest metrology equipment and skilled QA inspectors to keep every one of our products with high quality. Our professionals understand the need for accuracy and have rich experience in producing optical components, their experienced workforce is here to help. Whatever your requirement, from laser safety windows to imaging lenses system, we always find a solution.

Aluminum coated mirrors Aluminum coated mirrors are a good option for many general broadband. Protected Aluminum coating is used for mirrors, it have protected with a layer of silicon monoxide, making it suitable for laboratory and industrial use. The mirrors are usable from 450nm to the far infrared.UV Protected Aluminum coating is used for optical mirrors. They are coated with aluminum then protected with magnesium fluoride. The mirrors have a good reflectance at UV broadband. CLZ Optical provide the round, square and customized shape mirrors with a Protected Aluminum coating and UV Protected Aluminum coating in various sizes.

Optical Windows are flat, plane-parallel plates with ground and polished faces that often used as isolate two physical environments while allowing light to pass. Optical Windows should be selected based on the material transmission or mechanical properties of the substrate and Windows do not cause change in the magnification of a system. Square Optical Windows are available in UV Grade Fused Silica (FS) & BK7 Glass materials, the commonly used coatings are antireflection coating (AR). We supply a range of Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).

Fused Silica Optical Dome UV Fused Silica Domes is a good choice in the Solar Instruments. It including ultraviolet fused silica and infrared fused silica. For the silica, it has a good transmittance from 180nm to2650nm, then it is good choice the protected UV Radiometers. For the IR silica, it has broadband transmission from 200nm to 3600nm, it can keep the pyranometer has a wider spectral range, improved directional response, and reduced thermal offsets. And Fused Silica mechanical properties it better than N-BK7, Borosilicate. Some of high quality deep-sea housings is made fused silica dome, it have wide-angle and can be protective the deep-sea camera. Optical dome 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.

Optical domes for Pyranometer in High Quality At CLZ Precision Optics , we specialize in manufacturing glass optical Domes from customer supplied designs. Capable of creating sizes from 10mm to 124mm in Diameter. We are among the very few manufacturers in the world who possess this technology. 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. Slight departures from that rule are sometimes desired. Optical domes are used in IR missiles, for underwater photography as part of protective case and as a part of sun tracking solar collectors. The Pyranometer need protection of other electronic components and ability to rely on withstand wind and rain erosion by optical domes.

UV grade Fused Silica meniscus lenses from CLZ Optics One side of meniscus lens is convex, another side is concave. It can be a convergent lens or a divergent lens, which is decided together by refractive index, curvature and radius. CLZ Manufacturing Ranges Materials: Over 120 visible materials, Fused Silica Sizes: 15mm to 150mm Surface Accuracy: 1/10λ Surface Quality: 80/50 to 10/5 Radii: 5mm to Plano, +/-.1% tolerances or better UV grade Fused Silica meniscus lenses have one convex and one concave surface. The meniscus lenses can be useful to control laser beam of appropriate wavelength, it can minimise the spherical aberration. We manufacturing the UV grade fused silica lenses and coating multiayer AR coating for 250-400nm on both surface.

Plano-Convex Lenses Fused Silica Plano-Convex Lenses with 1064 nm Laser Line Antireflection V- Coating Fused silica Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point.With AR coated fused silica Plano-Convex lenses can offers best optical performance. Our AR 1064nm laser V-coating offers the low reflectance at 1064 nm for high transmission, reduce to surface reflection and scattering. And our coating have high damage resistance, it will be keep the lenses maintaining high durability. CLZ Precision Optics offers a wide range of high quality Spherical lenses for a variety of applications, including Plano Convex Lenses, Plano Concave Lenses, Bi-convex Lenses, Bi-Concave Lenses, Meniscus Lenses, Spherical Mirrors and Achromatic Doublets. We are good at supply custom lenses from your design, our manufacturing capacity from diameter 10mm up to diameter 200 in a full range of optical glass materials to meet most applications, and we are also offered in a wide variety of coatings to meet your needs and specifications.
