Reading field curves for heating devices
The reading field curves of the heating devices differ to some extent from the normal reading
curves due to the optics heating and are somewhat reduced in the reading field width as
well as in the reading field height!
•
The maximum opening angle
for all oscillating and deflection mirror devices
(BCL 558
i
…
100 H
)
is reduced to ±28°
(without heating = ±30°).
•
In addition, the maximum swivel range
for all oscillating mirror devices
(BCL 558
i
O
…
100 H
)
is reduced to ±12°
(without heating = ±20°). The deflection
mirror models (BCL 558
i
S
…
100 H
) are not affected by this limitation.
• The reading field curves and opening angles are unchanged for all line scanners with
heating (BCL 558
i
S
…
102 H
).
For details, please refer to the following reading field curves for the heating devices.
