0.40 NA, 6.25mm FL, HOYA Molded Glass Aspheric Lens

Product Details Precision Glass Molded Lenses Compact Sizes for Integration into Measurement Systems Multiple Glass Substrates Available HOYA Molded Glass Aspheric Lenses are used in applications that require lenses with small sizes and high transmission that correct for spherical aberration. These aspheric lenses are manufactured through a patented molding process that produces precision aspheric surfaces to minimize wavefront error. Their small diameters and thicknesses allow for these molded aspheric lenses to be integrated into measurement systems, biomedical instrumentation, or other optical tools. HOYA Molded Glass Aspheric Lenses are available in multiple glass types that offer higher refractive indices and lower dispersion than other molded glass aspheric lens offerings. Specifications General Type: Aspheric Lens Model Number: AH11_Z Physical & Mechanical Properties Diameter (mm): 6.38 +0.00/-0.02 Center Thickness CT (mm): 2.50 Clear Aperture CA (mm): 5.65 Bevel: Protective as needed Optical Properties Effective Focal Length EFL (mm): 6.25 @ 780nm Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
