3µW to 1W
Features ֺ
PD300-MS for measurement of optical intensity after the microscope objective. ֺ
Low angular dependence for high N.A. objectives. ֺ
Can be used with air, water or oil immersion objectives.
Description:
The PD300-MS is a Microscope Slide power sensor that measures optical power at the sample plane of a microscope. The silicon photodiode measures from 350nm to 1100nm at optical powers ranging from 3µW to 1W and is designed to be a microscopy power sensor that answers the needs of fluorescence excitation measurements. The thin power sensor has a footprint of 76.0 mm x 25.2 mm matching that of a standard microscope slide. The sensing area is sealed and cleanable, allowing it to easily measure the output of high NA objectives that use immersion medium such as water / oil / glycerol as well as in air. The PD300-MS microscope slide power meter comes with a 1.5 meter cable for connecting to a meter or PC interface.
