These objective feature diffraction limited molded glass lenses specially designed for collimating or focusing laser diodes. All objectives are offered with high numerical apertures to accommodate diodes with various divergence angles.
- Ideal for collimating or focusing
- Diffraction limited performance
- AR coated for high transmission
- Excellent wavefront quality
- Corrected for laser diode cover glass
- Microscope objective-type housing
Great Versatility for Use With Most Laser Diodes
Our aspheric lenses are diffraction-limited molded glass lenses with typical wavefront quality better than λ/20 rms. The objectives are corrected for standard laser diode cover glass and optimized specifically for collecting and collimating light output from laser diodes. As laser diodes commonly have fairly high divergence angles we offer various numerical aperture lenses (from 0.25 to 0.5) to match the divergence angle of the particular diode being used. Further, we offer multiple focal lengths to accommodate your specific collimated beam diameter. The objectives are made with aspheric elements with broadband MgF2 broadband AR coatings centered at 780nm, resulting in reasonably low reflectivity from visible through near IR wavelengths.
Standard RMS Threads
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.
