High Precision Polished Aspheric Lenses / AGL-E_AGL-G
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 unto 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.
