Description
515 nm single-longitudinal mode (SLM) laser diode module coupled with polarization maintaining (PM) fiber. High long-term power stability is ensured by TEC thermal stabilization, as well as thermal and optical feedback.
This product is discontinued, please, refer to our alternative - 520nm laser
Note:
In optical systems with strong back-reflections (e.g. more than 10%), the laser must be protected by using an optical isolator with at least 20 dB isolation. Typical applications include interferometry, confocal microscopy (especially working with reflective samples), etc. Failure to comply with these requirements will render the warranty void for cases of COD (Catastrophic Optical Damage) of laser diode facets.
Fiber Termination - FC/APC (AT):
8° polishing angle minimizes back reflections from fiber tip. This is necessary especially for SLM lasers.
