Verifying the Power Calibration
Laser
power
is
calibrated
at
the
factory.
IRIDEX
calibrates
the
power
with
the
aid
of
a
power
meter
and
a
delivery
device
with
known
transmission
characteristics.
The
factory
calibration
procedure
meets
the
requirements
established
by
the
National
Institute
of
Standards
and
Technology
(NIST).
On
an
annual
basis,
SL/SLx
owners
should
compare
the
delivered
power
to
the
power
setting
to
verify
that
the
console
is
still
operating
within
the
factory
calibration
parameters.
IRIDEX
recommends
using
the
following
power
meters
to
perform
the
verification
procedure:

the
power
calibration:
1.
Ensure

greater
than
5000
ms.
6.
Set
the
Interval
to
One
Pulse
7.
Select
an
intermediate
spot
size
setting

the
delivery
device
(if
applicable).
Using
very
small
spot
sizes
may
damage
the

sensor.
11.
Place
the
console
in
Treat
mode.
12.
