Microscope Slide Sensor
PD300-MS
-
The PD300-MS Microscope Slide sensor measures the power at the sample plane in a microscopy setup. The silicon photodiode measures from 350nm to 1100nm at optical powers from 3µW to 1W. The sensor has a footprint of 76.0 mm x 25.2 mm matching that of a standard microscope slide. The sensing area is sealed so that it can measure in an immersion medium such as water or glycerol as well as in air. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.

Integrating Spheres
-
Integrating spheres are used especially for measuring divergent light sources such as LEDs. The light is introduced through the input port, then reflected many times by the highly reflective interior of the sphere until it illuminates the inner surface uniformly. A detector samples a small fraction of this light to measure the total power input. Ophir integrating spheres have a highly reflective diffuse white coating for measurements independent of beam size, position and divergence. There are several sphere sizes, apertures and wavelength regions available. The large IS6 series has 2 configurations for measuring divergent or parallel beams.
