Overview of PD300-MS power sensor:

User's Manual

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.

Problem summary：

How to measure the light emitted from the oil immersed objective?

Just drop a drop of oil in the center of the sensor surface, and then immerse the objective lens in it. After measurement, just wipe the sensor and clean it before reuse.

The area of the sensor is large. Can you measure light at any point on it?

The sensor has a large area to "capture" the light emitted from the objective lens at a large angle. It is more accurate when the light is centered on the surface. The target on the back of the sensor should be used to locate the sensor.
