Cross-Polarized No-Oil Epiluminescence Microscopy for Improved Diagnosis of Pigmented Skin Lesions and Basal Cell Carcinoma
The DermLite incorporates cross-polarization filters that reduce reflection of light from the surface of the skin and permits visualization of the deeper structures. The light from the white Light Emitting Diodes (LEDs), is polarized linearly by a special filter and the image being viewed through the magnifying lens is also linearly polarized so as to cancel out the reflected light from the surface of the skin. This mode is called Cross Polarized ELM and has been extensively studied for the imaging of pigmented lesions for the early detection of melanoma.

Imaging Basal Cell Carcinoma (BCC) When imaging Basal Cell Carcinoma (BCC), the compression with a glass faceplate forces the blood out and the large number of blood vessels that characterize a BCC is not seen. Therefore, BCC is not detected very well when using a glass face-plate. BCC detection is clearly visualized with DermLite - without glass compression. Read opinion from leading dermatoscopy expert |

Imaging Telangiectesia
Small varicose blood vessels that are found on the face and the legs can be visualized with the DermLite, using its cross-polarization mode of imaging. This is an excellent tool for examining the small blood vessels before and after laser treatment.
Summary
Because the DermLite uses Cross-Polarized ELM, there is no need for a glass face-plate when examining most of the skin lesions including BCC. Over 90% of the skin lesions of interest can be examined without the need for oil and a glass face-plate. This mode of imaging is extremely fast and can be accomplished in a matter of seconds rather than several minutes when using the conventional and inconvenient oil-based imaging.
