Chattanooga product #27805. It’s a single-diode therapeutic laser applicator (a small probe/head), not a cluster.

What it is

• Type/Name: Single Laser Diode Applicator. Chattanooga Medical Supply+1
• Configuration: The 820 nm, 300 mW version in Chattanooga’s single-diode family. dunbarmedical.com+1
• Purpose: Used to apply low-level laser therapy / photobiomodulation to a small, precise treatment spot (trigger points, tendon insertions, small joint lines).

Core technical features

• Emitter layout: 1 true laser diode (no SLD or LED elements)
• Wavelength: 820 nm (infrared).
• Infrared in this band is chosen for deeper penetration compared with visible red wavelengths.
• Output power: 300 mW total (0.3 W). 
• “Laser-only” note: Explicitly listed as not supporting SLD or LED modes.

What features you get when it’s connected to a base unit

• Independent control of treatment parameters (time, dose, output, mode).
• Energy display in Joules or J/cm² for repeatable dosing.
• Continuous and pulsed modes with fully variable pulse frequencies.
• Real-time feedback showing energy delivered during treatment.
• Preset clinical indications tied to this applicator.
• User-defined protocol slots to save custom settings.

Compatibility

• Designed for and marketed as compatible with Chattanooga Genisys / Vectra Genisys TranSport Laser systems (i.e., it won’t operate standalone).
