Type/Name: Single Diode Laser Applicator (sometimes listed as “single applicator” or “single laser diode”)
Emitter layout: 1 true laser diode only — no LED or SLD elements in this head.
Intended use: localized photobiomodulation/low-level laser therapy where you want a precise spot rather than broad area coverage.

Wavelength: 850nm infrared (IR).
IR at this band is used for deeper tissue penetration vs visible red light.
Output power: 200mW total (0.2 W).
Configuration family: one of three Chattanooga single-diode options:
- 27840: 850 nm, 100mW
- 27841: 850 nm, 200mW (shown)
- 27805: 820 nm, 300mW

The applicator is hardware; the base unit controls dosing and modes. With 27841 attached, compatible Chattanooga systems provide:

Independent control of all parameters (time, dose, mode).
Energy display in Joules or J/cm² (so dosing is trackable/repeatable).
Continuous and pulsed treatment modes.
Fully variable pulse frequencies.
Real-time feedback of energy delivered.
Preset clinical indications tied to this applicator.
User-defined protocol slots to save custom settings.
Easy connection to Vectra Genisys/Genisys-family electrotherapy combo units with laser module.

Designed for Chattanooga laser systems such as Vectra Genisys / Genisys TranSport and also listed as compatible with Vectra Neo units that have the laser module.

27841 single diode (200mW): best for small, focused targets (trigger points, tendon insertions, tight joint lines).
More power than 27840, so faster dosing for the same small area.
Cluster heads (27811/27812/27808): designed for larger areas and faster coverage via multiple emitters.
