This instruction sheet tells us info regarding lux, spectral, computer interface, response, and light. In this instruction sheet you can get things about spectral response, sensitivity, light intensity, probe, and photodiode.
There are lots of info like light sensor, optics probe, light sensor, the light sensor, and calibration are described inside this instruction sheet. These are selected from the instruction sheet:
The PASCO CI-6504A Light Sensor and CI-6604 High Sensitivity Light Sensor are designed to be used with a PASCO computer interface to make measurements of relative light intensity. Through the use of the gain options on the sensor box and within ScienceWorkshop®, the Light Sensor has a working range of up to seven orders of magnitude, allowing application across a wide range of lighting levels. The CI-6504A is best suited for experiments performed at ambient light levels. At the lower end of the range, interference patterns of monochromatic light after it passes through single or multiple slits can be measured; at the higher end, measurements can be made of relative light intensities of daylight.
Also, this instruction sheet gives you discussion around output signal, gain, analog output signal, fiber optics, and fiber optics probe.
