Patent ID: 8760658

Claim:
A flow cell module for use in a liquid sample analyzer, the liquid sample analyzer including a radiation source, a sensing device and a liquid sample source, the flow cell module comprising: a module housing; a liquid core waveguide mounted in the module housing and configured to receive a flow of a liquid sample from the liquid sample source; an input optical fiber disposed in the module housing and configured to transmit radiation from the radiation source to the liquid core waveguide; an input termination on an input end of the input optical fiber; a first kinematic connection mechanism operative to bias the input termination in a first direction along a first axis while permitting displacement of the input termination in a first opposing direction along the first axis; and a second kinematic connection mechanism operative to bias the input termination in a second direction along a second axis while permitting displacement of the input termination in a second opposing direction along the second axis, wherein the second axis is transverse to the first axis; wherein: the first kinematic connection mechanism includes a first spring biasing the input termination in the first direction; and the second kinematic connection mechanism includes a second spring biasing the input termination in the second direction.
