					The EX-308 handpiece features a continuously adjustable spot size from 18 mm2 to 2 mm
round, with constant fluence. Operators can adjust the size and shape of the beam, even
while dosing, and deliver a consistent dose. Arms, legs, and back are quickly treated
with the largest spot size, while the small 2 mm spot allows precision treatments of
the face, neck, and scalp.

A brightly lit aiming beam corresponds to the size and shape of the dose-delivery
beam for easy, accurate, and rapid targeted treatments.

                                                                                                                                                    for Psoriasis and Vitiligo
The dose-delivery beam has a flat-top profile for uniform dosing and clearance.
Collimation eliminates surface scatter and facilitates therapeutic penetration
of the 308-nm for maximum clinical efficacy.

Weighing about 100 lbs, the EX-308 is small enough for any treatment room
and is easily portable.
