S100 / OPMI pico Operation
A target value in a range from 50% to 70% usually provides the best
exposure results.
Low light
This mode has the same function as the "Automatic" mode, but exposure
times greater than 1/50 (60) s are allowed, which can result in blurred
movements.
Manual In this mode you can set the exposure time under "Exposure time".
The setting range extends from 1/6 to 1/10000.
– Steps for PAL: 1/10000, 1/4000, 1/2000, 1/1000, 1/500,
1/250, 1/100, 1/50, 1/25, 1/12 and 1/6
– Steos for NTSC: 1/10000, 1/4000, 1/2000, 1/1000, 1/500,
1/250, 1/120, 1/60, 1/30, 1/15 and 1/8
2 Lightmeter
In "Light meter" you can choose between three types of exposure
measurement: small spot, large spot or integral.
The lightmeter function is active only when the brightness is to set
"Automatic" or "Little light".
Small spot
The exposure is measured in a very small area in the image center. This
measurement is suitable for work in narrow channels when an extremely
small illuminated-field diameter is being used.
Large spot The exposure is measured in an area in the image center. This
measurement is ideal for working with an eclipsed surgical field edge
(resulting from a reduced illuminated-field diameter).
Integral
The exposure is measured and averaged across the full video image.
This measurement is recommended for surgical fields that are fully and
evenly lit.
However, if the object of interest is not located at the image center,
the "Small spot" setting usually does not provide the desired exposure
result. Select either a larger area ("Integral" or "Large spot") or manual
exposure.
