DEVICE ERASURE
If the device is subjected to wavelengths of light below
4000 Angstroms, device erasure will commence. It is
therefore recommended to use an opaque label over the
window in the event the device will be exposed to lighting
for a long time. The UV dose for erasure requires a
wavelength of 2,537 Angstroms for a minimum dose of
25 Wsec/cm
2
. If using a UV lamp of 12 mW/cm
2
, the
exposure time is estimated to be 35 minutes. Devices
should be positioned within 1 inch of the lamp during the
erasure process. Permanent damage can occur to the
devices if exposed to UV light for an extended period of
time.
