Operation
HEINE DELTA
®
20 P lus Dermatoscope
For examination of hard to reach lesions use the small contact plate (8) in
place of the standard contact plate (1).
Use DELTA 20 P lus with immersion contact plate (1a, 1b, 8):
Prepare the skin by moistening with HEINE dermatoscopy-oil (use a cotton
swab) or disinfectant spray.
Turn the dermatoscope on by rotating the on/off ring (7) at the handle.
Gently
place the instrument so that the lesion is in the center of the contact plate.
The examiner’s eye should be as close to the eye-piece (3) as possible. Adjust
the focus ring until a crisp, clearly-focused-image is obtained.
Always use the device in combination with one of the filter inserts
(polarizing filter or neutral density filter).
Only use contact plates from HEINE.
Using the DELTA 20 P lus with polarizing contact plate (1c, 1d):
When using the polarizing contact plate, DO NOT prepare the skin with liquid
like dermatoscopy-oil or disinfectants.
Apart from that the general operation is the same as the procedure above.
Brightness control:
The voltage regulation electronics of the HEINE DELTA ® 20
P
lus Dermatoscope
guarantee constant brightness.
Pressing one of the two buttons on the instrument (2) will reduce the bright-
ness by 50% and will turn off 2 of the 4 LED’s resulting in lateral illumination
for improved contrast when viewing the pigmented structure.
An electrical conducting connection between camera, PC and a mains
power source is not permissible.
For documentation with a digital camera only, use the HEINE photo
adaptor and our recommend adaptor from the digital camera adaptor
range.
HEINE DELTA ® 20 T Dermatoscope
The DELTA 20 T allows for a rapid change from polarized to non-polarized
examination mode over a side switch. Application remains the same as the
DELTA 20
P
lus with the immersion contact plate (see above). A difference is
that no immersion fluid is required in the polarized examination mode.
HEINE
®
NC1 Dermatoscope
The device can be used in non-contact modus. To do this, the contact plate,
which is attached through magnets, must be removed.
Hold the device approximately 2cm above the skin area to be examined. Bring
your eye towards the eye piece (10) as close as possible and adjust the eye
piece focus until a sharp image is achieved.
Contact modus (with contact plate):
See HEINE DELTA
®
20 P lus Dermatoscope with polarizing contact plate.
An extra lens is integrated in the contact plate (11) which provides a 9 x magni-
fication when the contact plate is connected. Without the contact plate, a 6 x
magnification is achieved.
HEINE mini3000 ® LED/XHL Dermatoscope
Moisten the affected skin with HEINE dermatoscopy oil or comparable
with a cotton wool swab. Switch on the device and place it gently over the
lesion, so that it is in the center of the contact plate (12).
The examiner’s eyes should be as close as possible to the ocular (14). With
the free hand adjust the focusing ring (15) until a clearly focused image is
obtained. Using the scale on top of the dermatoscope you can control the
adjustment of the focusing ring. In most cases it is only necessary to set up
the focus once.
