Description

27841 – Laser Single Diode  850/nm 200Mw

What it is

• 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. 

Core technical features

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

What the head enables on the base unit (day-to-day “features”)

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.

Compatibility

• Listed as compatible with Chattanooga Vectra Genisys Laser / Genisys TranSport Laser therapy systems (i.e., it won’t operate standalone).

When you’d use 27841 vs other heads

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