| | | Oasis™ Monolithic Isolator and Aspheric Lens | | |
| | | |
| | | Oasis™ provides a compact solution by combining both an aspheric lens and an isolator Built as a monolithic design, it offers diffraction limited performance optics along with outstanding isolation. The designs are ideal for small form factor laser diodes in both single and multi-channel configurations. The Surface Mount configuration offers smaller form factors and exceptional value. The typical Surface Mount Oasis™ contains a 0.55 NA Finite Conjugate lens that couples a laser directly into a single mode fiber The Micro Fixture Bench configuration offers a stainless steel holder; which can be easily mounted and aligned with standard pick and place equipment and then soldered or welded into the package. It contains a 0.8 NA or 0.6 NA collimating lens, perfect for collimating most laser diodes. The isolator offers a choice of single, 1.5 and double stages of isolation dependent on your requirements. As with all of our products, LightPath® offers extensive support to our customers in designing and manufacturing custom configurations. These would include a wide selection of aspheric lenses and single, 1.5 and double stage isolation. | | |
