…This attenuator is used with OP-2 VIS, LM-2 VIS, OP-2 IR and LM-2 IR sensors
to allow operation up to 5W in the visible and 3W in the infrared regions.
The attenuator threads into the sensor in place of the light shield to
provide from 1100:1 to 950:1 attenuation. Each attenuator is…

…have a fast response time
and thus can be useful for looking at pulse
shapes. However, they saturate above approximately 1 mW/cm2, so attenuating filters must be used when operating at higher
powers.
The main drawbacks of photodiodes
are that they have smaller active areas,…
