Precision Polished Aspheric Lens 20mm Diameter 15mm Focal Length 780nm 0.5um
AGL-20-GB-15P
These precision polished aspheric lenses can condense the collimated light into the range of diffraction limited. These lenses are ideally suited for collimating the LD emitted light or focusing the collimated light into the optical fiber.
◦High numerical apertures for effective light condensing.
◦Surface irregularity of convex surface is less than 0.1μm for AGL-EA/AGL-GA series and less than 0.5μm for AGL-EB/ AGL-GB series.
◦Surface irregularity of convex surface is less than 0.1μm for AGL-EA/AGL-GA series and less than 0.5μm for AGL-EB/ AGL-GB series.
