Zircon 4 is a system of identification by the iris. It is used to control the access to restricted areas. Zircon captures an image of the iris when the user is looking at the mirror, behind which the scanner lenses are located. The scanner analyzes the image quality and determines the center of the pupil, the iris and its borders. After the image is captured, it is coded and searched for in the database. Finally access to the closed zone is granted or denied.


The scanner is installed at a height of 160 cm on the wall, in which all the necessary communications are rooted.
To access the restricted area the user comes close to the scanner so as to see the reflection of her eyes in the mirror on the front panel (approximately 40-60 cm from the scanner). The tilt angle of the scanner can be regulated manually. The scanning unit rotates by 30 degrees up and 15 degrees down.
If the person is too far to be scanned properly, the indication invites her to come closer (the upward arrow lights up). If a person is too close, the down arrow lights up. During scanning the face is backlit by the LED lights. For the LEDs not to blind the user, we designed matte light transmitting elements (white dotted line around the mirror), which scatter light and make it soft. In a second the system allows the user in (the green check mark lights up) or prohibits passage (the red cross).

Behind the front panel of translucent polycarbonate at the bottom of the device there is a camera and a speaker (the row of holes on the front panel).
To ensure efficient cooling of processors there is a large aluminum radiator with vertical grooves for air circulation at the back of the unit. I like that the device looks beautiful even where very few people see it.

Together with the client’s engineering department, we have developed the architecture, layout scheme, found the way to rotate the scanning unit, thought out the assembly sequence, adapted some elements of the casing to suit the available production technology. Parts of casing are produced independently to meet the technological requirements for injection press production process. But the photos above are of a pilot batch, so some parts are made by casting in silicon while other parts are produced on the milling machine.
