Keysight 5517C-C01 HeNe Laser Red Interferometer Laser 480uW Split Freq: 2.9MHz

Manufacturer: Keysight

Model: 5517C-C01

Condition: Used. Comes in non-original packaging. This laser is in Fair cosmetic condition with scuffs/scratches/minor dings outside.  There is a label on top that says "Removed from STP29 Laser Ready LED Blinking"  The gaskets on both end covers are torn but still stay in place with careful installation.
The photos show the exact item(s) the buyer will receive.

Notes: This laser is in at-least-partial working condition. We lack the proper controller, so we applied power directly to the high tension supply inside. The +15V POWER ON and LASER ON lights illuminated. The READY light flashed green, we went to lunch, and it had a steady READY light when we returned.  A red light was emitted from the output (it looks kinda orange in the picture because reasons). We are not equipped to do proper output measurements on this laser, so no other testing was done.
No manuals, cords/cables, or additional items are included if not listed or shown.
