Abstract: A bioreactor control system comprises a batch server for controlling a bioreactor system in response to a recipe, a batch software system for generating a control sequence for the bioreactor system via the batch server for implementing the recipe, and a recipe conversion system that inputs the recipe into the batch software system. Preferably, the recipe conversion system reads a word processor file containing the recipe and interprets styles applied to text in the word processor file as indicating equipment and phases of the recipe to the recipe conversion system. Generally, the bioreactor system includes one or more bioreactors and additional hardware to perform the upstream and downstream processing. The document properties of the word processor file containing the recipe are applied as header information for the recipe input into the batch software system.

Abstract: Fluorescence microscopy systems with polychroic mirror changers are described. In one aspect, a polychroic mirror changer includes a polychroic-mirror array. The array includes a plate with a planar surface and a number of holes formed in the plate. The array also includes polychroic mirrors attached to the planar surface of the plate such that each polychroic mirror covers one of the holes and the reflective surface of each polychroic mirror is adjacent to and aligned with the planar surface of the plate. Each polychroic mirror is partially exposed through a corresponding hole to reflect a different subset of excitation channels of a beam of excitation light input to the changer. The polychroic-mirror array can be mounted in the changer so that when a different subset of excitation channels is selected to illuminate a specimen, the plate is moved within a single plane of motion.
Abstract: Illumination system for a microscope system capable of being mode-switchable between a first and a second illumination mode, comprising one source of light for providing a collimated beam of light, at least one selector mirror capable of being positioned in at least two positions to redirect the beam of light in two different beam paths, the first beam path being a direct exit beam path wherein the selector mirror redirects the beam of light along an exit beam path to provide a first illumination mode, the second beam path is a mirror loop path comprising two or more mirrors arranged to redirect the beam of light onto the selector mirror such that it is redirected by the selector mirror a second time along the exit beam path, and wherein mirror loop path comprises at least one optical element arranged to optically alter the beam of light to provide the second illumination mode.

Abstract: Illumination phase controls that provide precise and fast phase control of structured illumination patterns used in structure illumination microscopy are described. A coherent light source is used to generate a beam of coherent light that is split into at least three coherent beams of light. In one aspect, an illumination phase control is composed of at least one pair of rotatable windows to apply at least one phase shift to at least one of the beams. An objective lens is to receive the beams and focus the at least three beams to form an interference pattern. The phase control can be used to change the position of the interference pattern by changing the at least one phase shift applied to the at least one beam.

Abstract: Various superimposing beam controls that can superimpose beams of light with different optical properties are described. In one aspect, a beam control receives a beam of light and outputs one or more beams. Each beam is output in a different polarization state and with different optical properties. Superimposing beam controls can be incorporated in fluorescence microscopy instruments to split a beam of excitation light into one or more beams of excitation light. Each beam of excitation light has a different polarization and is output with different optical properties so that each excitation beam can be used to execute a different microscopy technique.

Abstract: Methods and apparatus are described for delivering index-matching immersion liquid in high numerical-aperture optical microscopy and lithography. An array of immersion liquid droplets is delivered to a specimen substrate or specimen substrate cover by an immersion liquid printing apparatus. An immersion liquid reservoir provides immersion liquid to the printer by a precision pump. The printer delivers immersion liquid to the substrate or substrate cover in arrays of immersion liquid droplets of defined volumes and array patterns. The volumes and patterns of array droplets delivered to the substrate or substrate cover are optimized to maintain adequate immersion liquid between the substrate or substrate cover and an immersion objective while avoiding the formation of air bubbles in the immersion liquid and the accumulation of excess volumes of immersion liquid.
