Sapphire Domes Sapphire has the characteristic of high hardness,hign strength, high transmittance,with high resistance to thermal shock quality factor, excellent performance on themal-shock resistance and abrasion resistance. CLZ Precision Optics’ Sapphire Domes are an ideal way to shield other optical components  without sacrificing the field of view of the optics inside. Sapphire domes can provide a very strong and durable protective environment to house other Optical Dome . Sapphire domes are ideal for visible and near IR optics applications. Sapphire domes are much stronger than glass domes at similar thicknesses while being much more scratch resistant. We have more than dozens of different sizes of domes and rich experience to manufacturing the optical dome, then we produce sapphire dome. Our sapphire is high quality dome, we can produce the concentricity less than 0.01mm and the TIR less than 0.01mm, The surface quality is better than 20-10. Also we can produce 1mm

Custom Domes CLZ optics is a manufacturer of optical components  in China. We are a leading manufacturer of optical dome  in the world. We have more than 20 different sizes of high quality optical dome (dome lens) in our product catalog. They are widely used in solar energy measuring instrument, underwater camera and high-pressure window of submersible.  Except product catalog dome, we manufacture custom optical dome .  Our domes manufacturing range: Diameter: 15 to 110mm Thickness variation: ± 0.01mm (diameter less than 35mm) ± 0.02mm (diameter 35mm to 60mm) ± 0.03mm (diameter 60mm to 110mm) surface quality: 20-10, 40-20, 60/40

Fused Silica Domes 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. In perfect domes the convex radius

Optical Glass Domes 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 e

Achromatic Lenses An achromatic lens , also referred to as an achromat, typically consists of two optical components cemented together, usually a positive low-index (crown) element and a negative high-index (flint) element. Due to the difference in refractive indices, chromatic aberration with respect to two selected wavelengths has been corrected. The lenses have been corrected for on-axis spherical aberration as well. Achromatic doublets are used as telescope objectives, eye loupes, magnifying glasses and eyepieces. Achromatic doublets have also been used to focus and manipulate laser beams because their image quality is superior to single lenses.  At CLZ Precision Optics , we specialize in manufacturing 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.  Here is Catalog of CLZ Achromatic Lens: Part Number Eff

Meniscus Lenses 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.

Bi-Convex Lenses Fused Silica Precision Lenses  for Solid State Laser applications UV Fused Silica Plano-Convex   Lenses  is a prime choice for lenses in use with Solid State Lasers due to its synthetic amorphous silicon dioxide of extremely high purity providing maximum transmission from 195 to 2100 nm. And Abbe constants of UV Fused Silica are also very similar to that of N-BK7 and excellent transmittance in the ultraviolet region. CLZ Optics' lenses are polished to tight tolerances to ensure minimum wavefront distortion. Tight surface quality tolerances minimize scatter and unwanted diffraction effects. We can do the fused silica lenses  have λ/8 surface irregularity and the surface quality have 20-10 scratch- dig.

Plano-Concave Lenses Plano Concave Lens, 40mm Dia. x -63.5mm FL, AR Coated R<0.25%@780nm, N-BK7 Lens The Plano-Concave Lens have one flat surface and one concave surface. They have a negative focal length and are used to diverge incoming light, or to increase focal length in an existing optical system. They can be used in beam expanders and projection systems.More details about Plano-Concave Lenses ， Optical   Lenses ， optical Coatings ， Prism ， Optical   Mirror ， Precision   Optics ， please contact us. CLZ Precision Optics specialize in manufacturing optical components from customer supplied designs, including a wide variety of Plano Concave Lenses. We can provide Featuring surface accuracy to less than 0.2 fringe measured at 633nm and finishes to 20-10 scratch-dig per MIL-PRF 13830, the material are fabricated from quartz, optical glass, silicon, etc. and the sizes up to 200mm diameter.
