Instructions
CAUTION: Prior to using the DermLite, read these instructions and
keep them in a safe place for future reference.
CAUTION: United States Federal Law restricts this device to sale
by or on the order of a physician.
CAUTION: The DermLite is designed for external examination only.
Introduction
The DermLite II Pro is a pocket epiluminescence microscopy
(PELM) device designed to view skin lesions with high magnification
and clarity.
A 25mm 10x lens combined with a unique button-activated variable
polarization system, allowing independent activation of two sets
of sixteen LEDs, provides for ideal skin microscopy. While one
set of sixteen LEDs produces glare-free, cross-polarized light by
canceling the reflected light from the skin, a second set provides a
polarized rendition of skin rich in surface detail. A high quality lens
with superb color correction and reduced image distortion is used
to image the skin. To facilitate the use of immersion fluids, and al-
low for fixed digital imaging, the unit is equipped with a retractable
faceplate spacer.
Directions for Use
CAUTION: Do not look directly into the bright LED light. Patients
must close their eyes during facial examinations.
IMPORTANT: Before initial use, please charge the internal lithium
ion battery for a minimum of 4 hours using the charger provided.
Hold the DermLite II so that the LEDs are aimed in the direction
of the lesion to be examined. Place the device approximately 1"
(~25mm) from the skin. Push and hold the power button (A) at the
left side of the unit for 2- 3 seconds to activate the LEDs.
Look through the lens with your eye placed 1"( ~25mm) to 4"
(~100mm) above the DermLite II. Move the device closer or further
away from the lesion to obtain the desired image focus. For oil
immersion imaging, or for camera use, rotate the spacer dial (B) so
that the white marker is at the 12 o'clock position. For fine focusing
within a range of +/- 1mm, simply rotate the dial to the left or right
between the 11 and 1 o'clock markers (C).
CAUTION: If the DermLite II Pro is used for oil immersion imaging,
place the oil only on the skin and then place the extended faceplate
spacer on top of the oil. Do not allow oil to contact the USB port, DC
charging port, or battery compartment
To attach the DermLite II Pro to a camera, the device is equipped
with a 28mm thread (D). A simple ring adapter (such as a 28-37mm
stepping ring) may be required to adapt the device to your camera
of choice. Please contact 3Gen or a photographic retailer for more
information.
Removable Faceplate (E)
The DermLite II Pro is equipped with a removable faceplate. To
remove this piece, rotate the spacer dial (B) to extend the spacer,
and twist off the small ring in the very front of the spacer.
Dual Polarization
The button located on the right side labeled "MODE" (F) lets you
toggle between two sets of sixteen LEDs with distinct polarization.
Each time the device is turned on, cross-polarized light, used to
examine deeper pigmentation, is automatically active. For skin
surface visualization, push the "MODE" button once. To toggle back
to the cross-polarized mode, push the button again.
Rechargeable Battery
After a minimum 4-hour initial charge, the lithium-ion battery
provides up to 2 hours of continuous operation, or enough power for
imaging approximately 600 lesions at 30 seconds per examination.
Once the battery is depleted, the unit will automatically shut off, and
will need to be recharged. Plug the charging cord into the round DC
charging port (G), and the red charging indicator (H) will illuminate.
Once the battery is fully charged, the green indicator will light up (I).
Optionally, you may use a USB cable to charge the unit via the USB
port (J).
CAUTION: When charging with a USB cable, the DermLite II
Pro must be connected only to the USB port of a computer that
complies with the IEC / EN 60950 standard to ensure continued
