Detailed Product Description



Custom Optically Finishing Flat Borosilicate Glass Lens With Linear Surface


  • Selection of Material: Borosilicate glass is chosen due to its high resistance to thermal shock, making it suitable for use in high-temperature environments.
  • Cutting and Shaping: The borosilicate glass is then cut and shaped to the desired dimensions using specialized tools and equipment. This process ensures that the lens has the correct size and shape for its intended application.
  • Polishing: The next step is to polish the surface of the lens to achieve the desired optical quality. This is typically done using a series of polishing steps, each with progressively finer abrasives to achieve the desired surface roughness and clarity.
  • Inspection: Once the lens has been polished, it is inspected for any defects or imperfections that may affect its optical performance. If any defects are found, the lens may need to be re-polished or discarded.
  • Application: used in its intended application, such as in lighting fixtures, telescopes, microscopes, or cameras. The lens transmits light while minimizing reflection and distortion, providing excellent optical clarity and precision.
  • Overall, the function of borosilicate glass lenses with a linear surface is to transmit light while minimizing reflection and distortion, allowing for high-quality imaging and measurement in a wide range of applications. The step-by-step process of cutting, shaping, polishing, inspecting the lens ensures that it meets the desired specifications for its intended use.
