These objective lenses have been specially designed for collimating and focusing laser diodes as well as fiber coupling. Since laser diodes have very large beam divergence, we offer various high numerical aperture lenses. Further, we offer multiple focal lengths to accommodate your specific collimated beam diameter. These lenses have all been corrected for the standard laser diode cover glass. We offer both multi-element and aspheric lenses.
Our multi-element lenses are precision optics with diffraction limited performance. They offer the best solution for more critical applications. Each is antireflection coated to maximize transmission. The F-L40B has a triple V-coating for peak transmission at 800, 1300, and 1550 nm.
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.
All of 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.
