CAUTION
1. Window Glass
The dust and stain on the glass window of the package degrade optical performance of CCD
sensor. Keep the glass window clean by saturating a cotton swab in alcohol and lightly wiping
the surface, and allow the glass to dry by blowing with filtered dry N2.
Care should be taken to avoid mechanical or thermal shock because the glass window is easily to
damage.
2. Electrostatic Breakdown
Store in shorting clip or in conductive foam to avoid electrostatic breakdown.
3. Incident Light
CCD sensor is sensitive to infrared light.
Note that infrared light component degrades resolution and PRNU of CCD sensor.
