Abstract: Clamps for operably coupling one or more optical components to a mounting block are provided. Clamps of interest include a frame and one or more flexure tabs attached to the frame. Light detection modules and systems including one or more clamps are also provided. Aspects of the disclosure additionally include methods for analyzing a sample and assembling a light detection module.

Abstract: Light detection systems are provided. Aspects of the light detection systems include first and second light receivers in fixed positions relative to each other, a plurality of wavelength separators configured to pass light from the first and second light receivers having a predetermined spectral range, and a plurality of light detection modules. Baseplates having a stage for mounting a light receiver, a plurality of recesses for fixing a plurality of light detection modules in rigid alignment relative to the stage, and a heat dissipation opening positioned within each recess are also provided. In addition, particle analysis systems, methods and kits for practicing the invention are disclosed.

Abstract: An elongated rectangular Rochon polarizer, e.g., having a height to width or depth ratio of at least 2.5, is securely held in a non-adhesive mounting assembly. The mounting assembly includes a plurality of compression elements that press the Rochon polarizer against corresponding reference points to properly align the Rochon polarizer within the mounting assembly. Moreover, air gaps between the Rochon polarizer and the sidewalls of the mounting assembly are provided to minimize thermal conduction between the mounting assembly and the Rochon polarizer and to provide thermal convection to cool the Rochon polarizer, thereby reducing risk of catastrophic delamination of the Rochon polarizer due to thermal effects.
