6.2 Lens protection window
The
Cyclops 160B
is supplied, as standard, with a protective window which
covers and protects the instrument lens.
CAUTION
Never look at the sun through this instrument
- this could cause
severe damage to the eye.
6.3 Fitting a Close-up Lens
To fit a close-up lens to the
Cyclops 160B
thermometer, unscrew the clear
protection window from the lens assembly and replace it with the relevant
close-up lens.
The optical transmission characteristics of the protection window and the
Type 135 close-up lens are similar. Therefore, there will be no significant
calibration error, so window compensation is not required. If a type 110
close-up lens is used, it will be necessary to set the window transmission
function to a value as specified with the individual lens (See Section 7.4).
