Selective Waveband Technology 

Selective Waveband Technology (SWT®) is a new and unique technology, combining the advantages of both Laser and Intense Pulsed Light systems, to create a new selective waveband system.

​​What is Dual Mode Filtering

Ellipse SWT® technology is more than intense pulsed light. Is a clinically proven technology based on the principle of Dual Mode Filtering. This means that Ellipse systems filter the light more effectively; not only removing the lower wavelengths but also – exclusively -, those higher wavelengths that do little to help the treatment, but make the treatment uncomfortable.Dual Mode Filtering technology is now an even greater asset, since we have been granted a U.S. patent for using water as one of our filters.


What is Square Pulse Technology (SPT)

Square Pulse Technology ensures that the pulse of energy immediately reaches the desired level, stays at that level for the duration of the pulse and immediately shuts down at the end of that pulse. This minimizes the risk of adverse effects.



Enhanced Treatments

Treat actinic keratosis, acne and reduce fine lines and wrinkles with PDT.

PDT laser represents the cutting edge of research in light based medicine, and works in two stages:

  • A photosensitizer is applied to the skin, and the body converts this into a chemical (often the naturally occurring chemical Protoporphyrin IX or PpIX).

  • The PpIX created a response to light within a certain waveband, provided by the Ellipse PR 530 or PL 400 applicators.


Two of the Ellipse SWT applicators are approved as the Light source for PDT treatments of the skin. The PR 530 applicator is already known for its use vascular and photo rejuvenation treatments. This applicator matches three of the PpIX absorption peaks, allowing a photochemical pathway to be added to existing acne and photo rejuvenation treatments.

Because of the wavelengths and pulse times used, the PR 530 applicator is suitable for patients of Fitzpatrick Skin Types 1 to 3, with zero or light suntan. The PL 400 applicator – the latest addition to the Ellipse PLUS series – matches all 5 PpIX absorption peaks. By offering a series of longer, low energy passes, it offers a comfortable PDT treatment suitable for slightly more tanned patients, or those of Skin Types 1 to 4.

The facts about PDT

There are numerous peer-reviewed clinical abstracts that show the safety and effectiveness of PDT treatments. A large number of these involve using a specific photosensitizer in a treatment such as rejuvenation, acne and actinic keratosis.

Photo Spray Intense®

A breakthrough topical photosensitiser designed to work in combination with Ellipse SWT treatment for wrinkle reduction. Ellipse wrinkle reduction treatment delivers visible improvements in as little as one month.

The photosensitiser is liposome encapsulated to safely and effectively transport the active ingredient deep beneath the surface of the skin. The spray ensures results with even greater safety.

Once Intense Photo Spray is absorbed into the skin, the formula's active ingredient is converted into protoporphyrin IX (PpIX). When activated by an appropriate light wavelength, a cytotoxic reaction begins in the treated skin cell. This triggers a cellular repair response and stimulates local collagen production. Externally the result is visible filling of facial wrinkles.



Shape from shading

Skin image reconstruction is achieved using the SFS technique, specially designed to minimise shading and optimise measurement accuracy.

Image reconstruction using this technique is applied in skin analysis, to determine wrinkle depth and widths, other lesions, and total skin roughness.


Unlike other skin analysis systems where only three colour channels (red, green, blue) are used, the Antera 3D system uses reflectance mapping of seven different light wavelengths, spanning the whole visible spectrum.

This allows for a more precise view and analysis of the colour features of the skin, which consists mainly of two chromophores, melanin and haemoglobin.
