Using The Filter Slider - Optika Italy IM Serie Manual De Instrucciones

14.6.2 Using the filter slider
• Moving the slider toward left or right to insert the
desired position. A click sound will confirm the proper
positioning of the slider.
1. When the position ① is inserted (provided that a ND
filter is installed) the light coming from the lamp housing
will be decreased, according to the filter type installed.
2. When the position ② is inserted, no filters are engaged
into the light path.
3. When the position ③ is inserted, the shutter is engaged
in the light path and therefore no light will come.
• We suggest to close the shutter by interrupting the
observation for a limited time and not subjecting the
sample to unnecessary lighting in the period in which
it is not observed. (Switching off and on frequently the
HBO lamp considerably reduces its duration).
