Precision Polished BK7/Fused Silica Optical Glass Lenses with Various Coatings

1. Core Product & Material Options

• Product Identity: "Optical Glass Lenses" is the broad, foundational product category. This term ensures capture of all general searches for custom or stock optical components.

• Material Specification (Dual-option): "BK7/Fused Silica" is a critical technical differentiator. It presents two premier optical glass choices:

  • BK7: Standard borosilicate crown glass, ideal for most visible light applications due to its excellent homogeneity and cost-effectiveness.

  • Fused Silica: Synthetic quartz with exceptional properties for UV transmission, high laser damage threshold, and low thermal expansion, catering to demanding laser and UV applications. Listing both expands the search reach.

2. Key Manufacturing Property & Surface Finish

• Lead Property (Precision Polished): This term is a primary quality indicator. It signals superior surface flatness (often specified as λ/10 or better), low surface roughness, and minimal subsurface damage. This is essential for applications requiring low scatter, precise wavefront control, and high laser damage resistance, differentiating the product from lower-grade polished lenses.

3. Critical Performance Enhancement

• Customizable Feature: "with Various Coatings" is a powerful value-added statement. It indicates the supplier provides customization and has coating capabilities. It implies availability of standard Anti-Reflection (AR) coatings for different wavelength ranges, as well as potentially more specialized coatings (e.g., metallic, dielectric, beamsplitter), allowing the lens to be tailored for specific optical functions.

4. Implied Function & Target Application

• The title is inherently versatile, designed for OEM integration and custom optical assemblies. Its applications are defined by the material and coating choice:

  • BK7 Lenses: Used in imaging systems, visible light lasers, magnifiers, and consumer optics.

  • Fused Silica Lenses: Critical for UV lithography, excimer lasers, high-power laser systems, and deep-UV spectroscopy.

• The combination of precision polish and coating options targets optical engineers, system integrators, and R&D departments across industries like biotech, semiconductor, defense, and industrial laser processing.
