FX 635 Laser

The FX 635 laser provides patients experiencing chronic pain with a new treatment option. This non-invasive, pain-free, efficacious solution targets pain centers and helps to relieve musculoskeletal conditions.

The FX Series lasers by Erchonia are the only low level lasers FDA cleared to treat:

  • Low back pain
  • Plantar fasciitis
  • Nociceptive musculoskeletal pain

Product Description

The FX 635 uses low-level laser technology and patented laser diode arms to precisely target pain centers. The body absorbs the light energy, which encourages the cell’s mitochondria to produce more ATP and promotes natural healing within the cell. Because the laser merely stimulates the cells to promote healing naturally, the FX 635 provides pain relief and reduces inflammation with no known side effects.

How it Works


Users remain awake throughout the entire laser treatment and experience no burning, scarring or downtime, allowing them to resume the rest of their day as soon as the session is over.

For Medical Professionals

Medical professionals have trusted Erchonia’s low-level lasers for treating various conditions for over 25 years and are increasingly turning to the useful benefits of LLLT to manage a range of conditions more safely and effectively.

The FX 635 offers the industry’s most marketable procedure due to its wide array of FDA Clearances including plantar fasciitis, chronic low back pain & overall musculoskeletal pain.

With the FX 635 medical staff can spend less time performing each treatment and use this valuable time to treat more patients and perform necessary tasks. Thanks to its triple-head, hands-free design, the medical professional just has to set up the FX 635 and go. This allows the physician to see other patients while the FX 635 does its work.
