Note: A quantity of acceptable near-infrared ray is 500 µW/cm 2 or less.
• Places near the light reflection (from a mirror, etc.)
• Places where the amount of light is not appropriate for operation
Keep the iris reader away in the following, in addition to the above surroundings.
• Vibration (It may cause invalid iris image capturing and recognition. It may also cause other trouble or damage.)
• Places whose humidity is not between 30 % and 80 % and whose temperature is not between 0 °C and 40 °C {between
32 °F and 104 °F}
If the iris reader is located in an area exceeding these ranges, it may cause damage or a malfunction.
• Noise (for example, places near air conditioners or ventilators)
• Electricity
When objects made of glass or acrylic, etc. are located between an iris reader and a user, enrollment or recognition
may fail due to the light refraction, light reflection, or sensor malfunction.
■ Installation Space and Recognition Range
● Keep the Installation Space.
The installation space described in the following illustrations is required.
Note: The height of the iris reader, shown in the figure, is a recommendation. The centre of the optical axis and upside/down-
side limit of the eye position will differ depending on the installation height.
● Check the Capturing Range.
If the height of the iris reader is 1 300 mm {54.3 in.} as
described in the previous "Side View" illustration, the recog-
nition range will become as follows.
Note: If your eye position is higher than the upside limit,
bend down. If your eye position is lower than the down-
side limit, get on a pedestal, etc.
