Abstract: In one embodiment, a flow cytometer is disclosed having a compact light detection module. The compact light detection module includes an image array with a transparent block, a plurality of micro-mirrors in a row coupled to a first side of the transparent block, and a plurality of filters in a row coupled to a second side of the transparent block opposite the first side. Each of the plurality of filters reflects light to one of the plurality of micro-mirrors and passes light of a differing wavelength range and each of the plurality of micro-mirrors reflects light to one of the plurality of filters, such that incident light into the image array zigzags back and forth between consecutive filters of the plurality of filters and consecutive micro-mirrors of the plurality of micro-mirrors. A radius of curvature of each of the plurality of micro-mirrors images the fiber aperture onto the odd filters and collimates the light beam on the even filters.

Abstract: An optical fiber forward scatter channel in a flow cytometer is disclosed. A detector system in the flow cytometer includes fiber optic cable for receiving scattered light from an incident laser light that is directed at cells/particles passing through the flow cytometer. The fiber optic cable delivers the scattered light to a sensor system, which collects data to perform analyses on the scattered light. Such analyses may include, for example, calculating the size of a cell/particle, counting cells/particles, and so on. The fiber optic cable is an inherently efficient and accurate filter for the acceptance or rejection of the scattered light.

Abstract: A flow cytometer or cell sorting system includes a linear array detector having a plurality of detectors; a plurality of low noise gain amplifiers respectively coupled to the plurality of detectors in the linear array detector; a plurality of analog to digital converters respectively coupled to the plurality of detectors of the linear array detector; and image reconstruction logic coupled to the plurality of analog to digital converters. The linear array detector receives the brightfield image of each cell of the plurality of biological cells and transduces the light into analog signals representative of pixels in a plurality of brightfield image lines of each cell. The plurality of analog to digital converters transduce the analog signals into digital numeric signals for each pixel. The image reconstruction logic reconstructs the plurality of brightfield image lines of each cell over time periods into a single overall brightfield image of each cell.

Abstract: A flow cell subassembly includes a carriage assembly coupled to a flow cell body to selectively engage a nozzle with a base of a cuvette. The carriage assembly includes a linear bearing slidingly engaged with the flow cell body, a tiltable carriage plate coupled to the linear bearing, and a nozzle mount coupled to the tiltable carriage plate. The nozzle mount receives a nozzle assembly with the nozzle. Set screws can adjust pitch angle of the tiltable carriage plate with the linear bearing to adjust engagement between the nozzle and cuvette in a first dimension. To adjust engagement between the nozzle and cuvette in a second dimension, axial play in bolts/screws through the tiltable carriage plate into threaded holes of the linear bearing allow for yaw angle adjustments.

Abstract: A crystal for flow cytometry with dual laser beams is disclosed. The crystal is a birefringent crystal comprising a material composition including a quartz mineral having a face side including a face angle of ninety degrees plus or minus one tenth of a degree; a wedge side that is substantially perpendicular to the face side, wherein the wedge side includes a wedge angle of two degrees plus or minus one tenth of a degree; and a major side that is substantially perpendicular to the face side and the wedge side. The major side includes a thickness of one and one-half millimeter plus or minus one tenth of a millimeter. A polarized light beam entering the birefringent crystal at an incident angle is separated into an ordinary light beam and an extraordinary light beam.
