Objective Lens, Laser Diode, Aspheric, 0.40 NA, 6.24 mm, 510-1550 nm

The F-LA11 Laser Diode Aspheric Objective Lens has been specially designed for collimating and focusing laser diodes as well as fiber coupling. This version has a 0.40 Numerical Aperture (NA) and a 6.24 mm focal length with 5 mm clear aperture lenses. These lenses have all been corrected for the standard laser diode cover glass. Our aspheric lenses are diffraction-limited molded glass lenses with typical wavefront quality better than λ/20 rms. Each is antireflection coated with MgF₂ centered at 780 nm for maximum transmission. These lenses offer an economical solution without sacrificing performance. These objectives are packaged in a microscope objective housing with standard RMS thread. They are compatible with our F-Series fiber coupling devices and ULTRAlign™ fiber positioners
