AI Technical Summary
Technical Problem
Optical probing of sample containers is complicated by variations in sample condition, type, and container properties, leading to unfocused light beams and reduced signal quality, especially with varying container diameters.
Method used
An optical system using a confocal arrangement of cylindrical lenses, aligned to coincide at the center of the sample container, maintains a perpendicular wavefront contact, compensating for diameter variations and ensuring focused light detection regardless of container size.
Benefits of technology
The system allows for accurate optical probing of samples in containers of varying diameters, improving sample quality checks and preventing resource waste by identifying unsuitable samples before processing.

Abstract
An optical probing system for use in a diagnostic laboratory system includes an imaging location at which a sample container is positioned, an optical source configured to generate an optical beam, and a first lens configured to receive the optical beam from the optical source and to generate a collimated beam. A second lens has a focal position within the imaging location and is configured to receive the collimated beam and focus the collimated beam at the second lens' focal position. A third lens has a focal position that coincides with the focal position of the second lens, a fourth lens is configured to receive the optical beam from the third lens, and an optical detector is configured to receive the optical beam from the fourth lens. Numerous other embodiments are provided.
