Single Channel Light Detection

Model: HO-IAD-SG-01
Multi angle measurement
Rotation stage is driven by worm gear assembly

A scattering photometer for measuring the intensity of light scattered by particles has been developed by Holmarc for environmental research. It is a precision instrument designed for spectroscopic measurements of scattered light. This goniometer based instrument provides controlled multi angle measurement of particles.

A 100mw laser beam (532nm) is directed first to a linear polarizer and then into a scattering compartment containing the particles under study. The scattered light is focused onto APD (Avalanche Photo Diode) detector to generate an electrical signal indicating the amount of scattered light at that position. The motorized rotation stage helps to take reading at different angles. The entire operation is automated through a personal computer. Custom developed software and interfacing electronics are supplied along with the system.

Laser source is mounted on a precision rotation stage with central access hole. The stage is driven by stepper motor. Sample is introduced through the center hole of the stage. As the stage along with the laser source rotates, output data from the detector is collected automatically and saved in the computer with reference to the angular position of the rotation stage.
