   <video:title>Custom Made  Achromatic Optical Lenses 2mm-200mm Diameter Lightweight</video:title>
   <video:description>Achromatic Lens Gluing lenses, also called achromatic lenses, consist of two lenses of differentmaterials glued together.The performance of the achromatic lens in polychromatic (whitelight) imaging is much better than that of the single lens. The achromatic lens is designed to reduce or eliminate chromatic aberration.Gluinglenses are suitable for a variety of applications such as fluorescence microscopy, imagerelay, detection, or spectroscopy applications.

   <video:description>Plano - Convex Spherical Lens Plano-Concave Spherical Lens A plano-convex lens is a convex lens with a positive focal length. This type of lens isused to focus parallel light or convert point sources into parallel light. And it is usually usedin related applications such as narrowing beams of light, reducing the focal length orenlarging images. The coated lens is also widely used in the visible and near infraredfields. We can supply design,producing,coating. cementing</video:description>

   <video:description>Plano-Convex / Concave Lens Double-Convex / Concave Lens Product Description: Double-Convex Lenses are the best choice where the object and image are atequal or near equal distance from the lens. When the object and image distance areequal (1:1 magnification), not only is spherical aberration minimized, but also comadistortion, and chromatic aberration are identically canceled due to the symmetry. Biconvex lenses function similarly to plano-convex lenses in that they have a</video:description>

The spherical aberration of the Plano-Concave lenses is negativeand can be used to balance aberrations created by other lenses. Similar to thePlano-Convex lenses, the curvature surface usually faces the largest objectdistance or the</video:description>

   <video:title>High Performance Large Aperture Optical Glass Lenses Custom Optical Lenses</video:title>
   <video:description>Large Aperture Optical Lens A large aperture optical lens is a high-performance lens characterized by its ability to transmit light efficiently due to its large clear diameter, or &amp;quot;aperture.&amp;quot; This term is most commonly used in the context of photography, astronomy, and other optical applications where the amount of light gathering is crucial. Key Features and Considerations: 1. **Light Gathering Ability**: The primary advantage of a large aperture lens is its superior light</video:description>

   <video:title>Custom Made Achromatic Optical Lenses 5mm-150mm Diameter Achromatic Aspheric Lens</video:title>
   <video:description>Achromatic Lens Gluing lenses, also called achromatic lenses, consist of two lenses of differentmaterials glued together.The performance of the achromatic lens in polychromatic (whitelight) imaging is much better than that of the single lens. The achromatic lens is designed to reduce or eliminate chromatic aberration.Gluinglenses are suitable for a variety of applications such as fluorescence microscopy, imagerelay, detection, or spectroscopy applications.

   <video:title>High Precision Achromatic Optical Lenses Achromatic Cylindrical Lens Multipurpose</video:title>
   <video:description>Achromatic Lens Gluing lenses, also called achromatic lenses, consist of two lenses of differentmaterials glued together.The performance of the achromatic lens in polychromatic (whitelight) imaging is much better than that of the single lens. The achromatic lens is designed to reduce or eliminate chromatic aberration.Gluinglenses are suitable for a variety of applications such as fluorescence microscopy, imagerelay, detection, or spectroscopy applications.

   <video:description>Product Description: Double-Convex Lenses are the best choice where the object and image are atequal or near equal distance from the lens. When the object and image distance areequal (1:1 magnification), not only is spherical aberration minimized, but also comadistortion, and chromatic aberration are identically canceled due to the symmetry. Biconvex lenses function similarly to plano-convex lenses in that they have a positivefocal length, and focus parallel rays of light to</video:description>

   <video:description>Product Description: Double-Convex Lenses are the best choice where the object and image are atequal or near equal distance from the lens. When the object and image distance areequal (1:1 magnification), not only is spherical aberration minimized, but also comadistortion, and chromatic aberration are identically canceled due to the symmetry. Biconvex lenses function similarly to plano-convex lenses in that they have a positivefocal length, and focus parallel rays of light to</video:description>
