ABSTRACT:
A nephelometer is disclosed which employs immersion optics and conformable optical couplers between components to minimize scattered background light. A multi-compartment micro volume specimen holder employs a cover having integral spacer knees which assure a precision length optical path. The device has the ability to collect small forward-angle scattered light with maximum efficiency and sensitivity. Light pipes are employed to remove a glass-air interface to a remote point where scattering is of much less importance and to act as an axicon for the compact collection of angularly scattered light.
