Uncoated Double-Concave Lenses

Uncoated Double-Concave Lenses

CLZ Optical Co., Ltd. offers uncoated biconcave lenses that feature both surfaces concave inward, creating a unique hyperbolic structure.CLZ's biconcave lenses are made from H-K9L optical glass to ensure light passes smoothly without significant absorption or scattering. Biconcave lenses can be used for beam expansion, specific corrections in imaging systems, or as components in certain optical instruments to help adjust and control the path and characteristics of light. Depending on the particular needs and scenarios, CLZ offers uncoated biconcave lenses that may also be used in other scenarios where beam spreading or specific optical properties are required, such as certain medical, environmental, chemical, or electronic applications.

CLZ can also provide other transmittance enhancement films suitable for visible light and near-infrared, please feel free to contact us if you have any needs.
