What is a meniscus lens <br>Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens. <br> <br>Description Of Meniscus Cylindrical Lens <br>It is a lens that one surface is the convex shape, another surface is concave with a cylindrical shape, its role is making beam converging or diverging on a plane, and that beam doesn’t work for the perpendicular plane(cylindrical axis) with it. A cylindrical lens is used in turning a transmitted plane wave into a cylindrical wave, or turn an original cylindrical wave into a plane wave or spherical wave, such a kind of lens can correct ocular astigmation. <br>Ecoptik (also known as BRD Optical) uses classical processing technology and strict process control to ensure that the surface accuracy of the lens is sufficient to meet customer requirements. At the same time, we use the Zygo interferometer to perform multiple corrections and measurements during and final processing of the surface progress. <br> <br>Specification Of Meniscus Cylindrical Lens <br> Commercial High precision <br>Material Optical glasses, fused silica, silica, etc. <br>Diameter 0.5mm ~ 150mm <br>Diameter tolerance ±0.1mm ±0.02 <br>Focal length -50mm ~ 2000mm <br>Focal length tolerance ±2% (&lt;10mm) <br> ±0.5% &lt;10mm – 1000mm) <br> ±1% (&gt;1000%) <br>Centraticom &lt;3 arc min &lt;10 arc sec <br>Clear aperture &gt;85% ~92% of diameter <br>Surface quality ( Scratch / Dig) MIL 60/40 MIL 10/5 <br>Surface accuracy λ/[email protected] λ/10632.8nm <br>Bevel 0.05mm~0.2mm x 45° <br>Coating Up on  customer’s requirement. <br>For more information about cylindrical lens price, please feel free to contact us! <br> <br>If you are looking for a reliable custom optic manufacturer, don&#039;t hesitate to contact us! <br>#cylindrical#lens#price <br>[a]https%3A%2F%2Fwww.ecoptik.net%2Fproducts%2Fmeniscus-cylindrical-lens%2F[/a]

#dielectric #mirror #buy <br>The double convex lens/double convex mirror is symmetrical across both its horizontal and vertical axis. Each of the lens&#039;s two faces can be thought of as originally being part of a sphere. The fact that a double convex lens/mirror is thicker across its middle is an indicator that it will converge rays of light that travel parallel to its principal axis. A double convex lens/mirror is a converging lens. A double concave lens/mirror is also symmetrical across both its horizontal and vertical axis.

#cut #off #filter <br>A dielectric mirror, also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material. By careful choice of the type and thickness of the dielectric layers, one can design an optical coating with specified reflectivity at different wavelengths of light. Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser. Mirrors of this type are very common in optics experiments, due to improved techniques that allow inexpensive manufacture of high-quality mirrors. Examples of their applications include laser cavity end mirrors, hot and cold mirrors, thin-film beamsplitters, and the coatings on modern mirrorshades. Ecoptik (also known as BRD Optical) has various dielectric mirror glass for sale.

#retroreflector #prism <br>BK7 and UVFS Corner Cube Retroreflector Prism are designed to deviate incident light by 180 degrees independently of an angle of incidence. These corner cube prism have three mirror surfaces with angles at 90° to each other, juxtaposed to form the corner of a cube with the entrance face perpendicular to the cube&#039;s diagonal. <br> <br>Corner Cube Retroreflector Prism Description <br> <br>A corner cube retroreflector, also known as a CCR or trihedral optical prism, is an optical structure that consists of three adjacent, mutually-orthogonal plane-reflecting surfaces which form the corner of a cube. The corner cube reflects an incident ray at a specific angle, independent of the prism and beam orientations. <br> <br>Ecoptik corner cubes are used in a wide variety of applications such as spectroscopy, battlefield technology and satellites. Corner cubes enable range finding for weapons systems and aid in performing other precise displacement and distance measurements. For example, a satellite in orbit around the earth requires monitoring of its position while it measures plate tectonics and ocean surface topography. <br> <br>There are many optical component manufacturers, but we are one of the best choices for you. <br> <br>[a]https%3A%2F%2Fwww.ecoptik.net%2Fproducts%2Fcorner-cube-retroreflector%2F[/a]
