FAQ - Frequently Asked Question

HEINE DELTA 30 Dermatoscope


Contact mode vs. non-contact mode


When it is advisable to perform an examination in non-contact mode?

When examining hard-to-reach areas (e.g. between the toes or fingers) where direct contact with the lesion is difficult – and, in rare cases, where there is a risk of infection – it may be advisable to use the HEINE DELTA 30 / PRO and DELTAone without the contact plate fitted (i.e. in non-contact mode). This enables better visualisation of hard-to-reach lesions and the possibility of viewing infectious lesions without coming into direct contact with the skin.

Can the contact plate be removed and replaced? How can I remove the contact plate?

The contact plate can be removed from the device:

  • to be disinfected and, if necessary, sterilised (large contact plate)
  • to perform examinations in non-contact mode
  • to be replaced with the small contact plate or the diSTANCE working ring

The contact plate can be easily removed from the dermatoscope by slightly twisting it and gently pulling it at the same time.


What is the small contact plate for?

The small contact plate of the HEINE DELTA 30 / PRO and DELTAone is specifically designed for examining hard-to-reach pigmented lesions.

What is the difference between an examination performed in contact mode and an examination performed in non-contact mode?

Thanks to the removable contact plate, the HEINE DELTA 30 / PRO 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.

Can the HEINE DELTA 30 / PRO and DELTAone be used without the contact plate?

Yes, the HEINE DELTA 30 / PRO and DELTAone dermatoscopes can be used without the contact plate for non-contact examinations.


Digital options


How do I take the best images with my smartphone?

1. Set the focus ring to the neutral position in the centre, indicated by a broad line.

2. Connect your smartphone to the dermatoscope using the available Smartphone Connector.

3. Open the camera app or the corresponding DERManager app on your smartphone, focus the image using the smartphone’s autofocus and take a picture.


How can I connect my Smartphone to my dermatoscope?

Both, the HEINE DELTA 30 /PRO and DELTAone can be connected to almost any smartphone via the Universal smartphone connectorin combination with a suitable mobile phone case for the phone in question. You can find assembly instructions here.

HEINE provides preconfigured mobile phone cases for most current iPhone* models.

HEINE offers HEINE DERManager to support digital documentation.


Is there a digital documentation app?

HEINE offers DERManager for the purpose of digitally documenting dermatological images. There is no need for expensive hardware; the number of users, devices and rooms is unlimited, and there are no annoying cables getting in your way. We take care of migrating data from your existing documentation system on request.


General


How can I change the light intensity?

DELTA 30 / PRO

To change the light intensity, press the button on the right-hand side of the device. You can switch between the 3 options by pressing the same button several times. This allows you to select your preferred light intensity. When you switch the device back on again, the light intensity that was last used before the device was switched off is automatically restored.

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.


What type of liquid can be used as an 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.

What happens if I forget to switch off the device?

The device switches off automatically after 10 minutes if the polarisation button or the light intensity controlleris not used. This feature ensures that the battery does not discharge unintentionally and that the device remains ready for use.


What is the purpose of the different illumination options?

In daily practice, you examine patients with different colours and types of skin. The HEINE DELTA 30 / PRO and DELTAone allow you to choose between 3 different light intensities to adapt the light intensity to the variety of diagnostic situations and the examiners’ preference.


What is the polarised illumination mode?

In polarised working mode, the light reflected on the skin is blocked out by a polarisation filter. This provides better visualisation of deeper layers of the skin, similar to the effect of using a non-polarised working mode in combination with immersion fluid. Depending on the structures to be examined, some are better detected with polarisation and others without. For example, vascular patterns can be examined more closely with polarisation. The horn cysts of seborrheic keratosis, on the other hand, are easier to see without polarisation.

What is the difference between polarised and non-polarised illumination?

The main difference between polarised and non-polarised dermatoscopy is the depth of the visualised structures of the skin. While non-polarised dermatoscopy is most suitable for examining structures in the superficial layers of the skin, polarised dermatoscopy is more suitable for examining the deeper layers of the skin.

How do I switch on the polarised illumination mode?

DELTA 30 / PRO

When the device is switched on, it automatically starts in the polarised illumination mode. The polarised working mode is indicated by the blue LED on the left-hand side of the device lighting up. To switch off the polarised working mode, press the ‘P’ button next to the power button in the middle of the device. Pressing the same button reactivates polarised mode.

DELTAone

When the instrument is turned on, the device automatically starts in the 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 the small black button next to the blue LED. Pressing the same button reactivates polarised mode.

How close do I have to get to the dermatoscope to make a diagnosis?

The HEINE DELTA 30 / PRO 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.


Do I have to use immersion liquid?

Using immersion liquid reduces reflections during the examination. During examinations with polarised illumination, you do not need immersion liquid, as the light reflected on the skin is blocked out by the polarisation filter.
