Heine Delta 20T Dermatoscope

HEINE DELTA 20 T Dermatoscope Set with USB Rechargeable Handle

The HEINE Delta 20T [K-10.28.388] is a high-quality dermatoscope with HQ LED illumination that can be used for contact dermoscopy with an immersion liquid (e.g. immersion oil) or for non-contact dermoscopy with polarised light. This makes the Delta 20T particularly flexible and offers the proper exam method for every lesion.

Built into the Heine Delta 20T is a precision lens in the shape of an achromatic optical system, which delivers razor sharp, high-resolution images with 10x to 16x magnification. This makes diagnosis extremely simple. 
 

A special advantage is the LED illumination in Heine quality through with an absolutely natural colour resolution is displayed. This property is especially important when assessing the colouration of liver spots. 

The Delta 20T can be combined with various batteries, rechargeable handles and the practical Heine charging station.

The Delta 20T Toggle Function

The toggle function is one of the significant specialties offered by the Heine Delta 20T. With this function, one can switch back and forth between polarised and non-polarised light at the touch of a button.

For many other dermatoscopes, it is necessary to change the contact plate in order to view the skin lesions under different lighting conditions, which poorly compares to the Delta 20T due to the time delay.
 

By switching between polarised and non-polarised light, a sort of signal appears on certain structures that is also known as a "Blink Sign". This signal emerges because certain structures appear differently under various lighting conditions. Blood vessels and crystalline structures appear as white lines when changing from non-polarised to polarised light, while milia are easier to recognise under non-polarised light.

In the example (left), one can see the illumination of a basal cell carcinoma when using the toggle function.

The Heine Delta 20T as a hybrid dermatoscope is ideally suited for evaluating all types of skin changes.
