Basic Concepts of VEINCAS Vein finder​
Near infrared light penetration ability is stronger than visible light, and the hemoglobin in the blood has better absorption towards NIR than other tissues.

Visible light

 Visible light can penetrate into the skin 1~2mm depth only, and most of it is reflected and scattered.

Infrared light

Infrared light penetrates deeper into the skin and reaches the dermis where the superficial veins are located.

Epidermis

Superficial vein 

Subcutaneous Tissue


Projecting infrared light of a specific wavelength to the skin
Collecting infrared images of skin with photosensitive elements
​
Processing digital image to form a blood vessel distribution map
​
The image of vein map is clearly projected back onto the surface of skin
