FAQ - Frequently Asked Question
HEINE DELTAone Dermatoscope
General
What is the difference between an examination in contact mode and in non-contact mode?
Thanks to the removable contact plate, the HEINE DELTA 30 and DELTAone can both be used for examinations in contact mode and in non-contact mode.
In contact mode, the patient is examined with the dermatoscope directly applied to the skin, while in non-contact mode, the patient is examined with the dermatoscope at a distance of approximately 1 cm from the skin, having removed the contact plate.

What happens if I forget to switch off the device?
The device switches off automatically after 10 minutes if the polarisation button or the brightness control is not used. This feature ensures that the battery does not run down unintentionally and that the device remains ready for use.
How close do I have to be to the dermatoscope for diagnosis?
The HEINE DELTA 30 and DELTAone are designed to offer you a high flexibility in regards to the viewing distance. The optic offers you a crystal clear image, no matter if you prefer a closer or a greater working distance.
What kind of fluid can be used as immersion liquid?
The best option is immersion oil, but even disinfection spray or water can be used to reduce reflections when working in non-polarised mode.

When is an examination in non-contact mode recommended?
During clinical examination of hard-to-reach-areas (e.g. between the toes or fingers), where direct contact with the lesion is difficult, as well as in rare clinical cases with infection risk, it can be recommended to use the HEINE DELTA 30 and DELTAone without the contact plate mounted – in non-contact mode.
This offers a better visualisation of hard–to-reach lesions as well as the opportunity to observe infectious lesions properly without direct contact with the skin.

Can the HEINE DELTA 30 and DELTAone be used without the contact plate?
Yes, the HEINE DELTA 30 and DELTAone dermatoscopes can be used without the contact plate for non-contact mode examination.
What is the small contact plate for?
The small contact plate of the HEINE DELTA 30 and DELTAone is specifically designed for the examination of difficult-to-reach pigmented lesions.

Can the contact plate be removed and exchanged? How can I take off the contact plate?
The contact plate can be detached from the device:
• To be cleaned and sterilised.
• To examine in non-contact mode.
• To be exchanged with the small contact plate.
To easily remove the contact plate from the dermatoscope, please give it a light twist in combination with a slight pull.
An additional possibility for the DELTAone is to turn the focus ring all the way to the right. Once you feel a resistance, give it an additional turn and the contact plate will fall off. Please make sure to safely hold the contact plate while performing this action to prevent the contact plate being dropped.
How can I clean the instrument and the contact plate?
A wipe disinfection of the instrument and the contact plate should be performed after each patient’s examination.
Additionally and in case of a utilization in semi-critical conditions, the new HEINE dermatoscopes are the only instruments which offer you the opportunity of a steam sterilization of the contact plate.
For detailed information, please refer to the hygienic reprocessing instructions on www.heine.com.
What is the polarised illumination mode?
In polarised working mode, the light reflected on the skin is suppressed by a polarisation filter. This offers a better visualisation of deeper skin layers. This is similar to the effect of using a non-polarised working mode in combination with immersion liquid. Depending on the structures being examined, some are better identified with polarisation, while others are better identified without. For example, vascular patterns can be viewed more precisely with polarisation.
However, the horn cysts of seborrheic keratosis are more prominent without polarisation.

What is the difference between polarised and non-polarised illumination modes?
The main difference between polarised and non-polarised dermoscopy is the depth of
skin’s visualized structures. While non-polarised dermoscopy is best suited for the examination of structures in the skin’s superficial layers, polarised dermoscopy is more adapted to the examination of the deeper skin layers.

How to turn on the polarised illumination mode?
DELTA 30
When the instrument is turned on, the device automatically starts in polarised illumination mode. Polarised working mode is indicated by the illuminated blue LED situated on the left side of the instrument. To turn off the polarised working mode, please press on the button -P- situated on the left of the power button in the middle of the instrument. Pressing the same button reactivates the polarised mode.

What are the different illumination options for?
In daily practice, you see patients with different skin colors and different skin types. The HEINE DELTA 30 and DELTAone allow you to choose from 3 different levels of light intensity to adapt the brightness to the diversity of diagnostic situations and the examiners’ preference.
How to change the intensity of the illumination?
DELTA 30
To change the level of light intensity, please press the button situated on the right of the power button in the middle of the instrument. Pressing the same button several times will switch between the 3 options. Please choose the illumination of your preference. When turning the device back on, it will automatically restore the illumination level that has been used last before turning the device off.
DELTAone
To change the level of light intensity, please press the small black button situated on the right side of the instrument. Pressing the same button several times will switch between the 3 options. Please choose the illumination of your preference. When turning the device back on, it will automatically restore the illumination level that has been used last before turning the device off.
Do I have to use immersion liquid?
Immersion liquid is used to reduce reflections during examination. When examining with polarised illumination, you do not need immersion liquid, since the light reflected on the skin is suppressed by the polarisation filter.
