A high-precision, low backlash linear actuator drive mechanism characterized by minimal positional repeatability error irrespective of the direction from which a selected or target position is approached may comprise a bellows coupling operative to transmit rotational motion from a motor to a drive spindle. Rotation of the drive spindle causes linear translation thereof in an axial direction.

A system and method of cooling a CCD camera may employ a composite material housing design that allows the cold side of a TEC to be mounted relatively close to the CCD and the hot side of the TEC to be isolated from the housing cavity in which the CCD resides. An efficient heat transfer path may facilitate cooling the CCD to a predetermined or selected operating temperature and isolate the CCD from the heat loads generated by operation the TEC.

A microscope stage with a flexural axis may exhibit predictable flexure characteristics and limited cross-coupling translations. Z motion of a Z plate proximate to a Z actuator may be substantially linear, while a distal side of the Z plate may be allowed to rotate about a hinge axis associated with a flexural component.

A structured-illumination module included in a 3D-structured-illumination-based fluorescence microscope, the structured-illumination module comprising: a structured-illumination-module frame; a beam-alignment module including a central tilt mirror coupled to an underside of a top horizontal plate of the structured-illumination-module frame; a set of directional mirrors, one of which receives, at a given point in time, input, polarized, coherent light reflected from the central tilt mirror; three sets of beam splitters, on three arms of the structured-illumination-module frame, the each splits an incident illumination beam, reflected to the set of beam splitters from a directional mirror of the set of directional mirrors, into a coherent beam triplet; and a phase-shift module that receives a beam triplet, at a given point in time, generated by one of the sets of beam splitters and reflected from the beam-alignment module and that introduces a desired relative phase relationship among the beams of the beam triplet.

The method of illumination of a microarray sample may contribute to the signal-to-background ratio. An oblique illumination technique is used to reduce the reflections from the sample to the detector. The sample may also be moved to the backside of the sample support to reduce the reflections caused by the sample support. In addition, a parallel scanning technique may be used to ensure proper alignment of the sample.

A precision controlled fast valve includes a diaphragm, a piezo actuator, and a plunger. The plunger is adapted to engage the diaphragm to create a seal which closes the valve. The piezo actuator is attached to the plunger and adapted to receive control signals which define the distance and speed of travel of the plunger. A control signal is received by the piezo actuator which causes the plunger to rapidly travel to a first position which is proximate to the diaphragm but does not create a seal. A second control signal is received by the piezo actuator which causes the plunger to pinch the diaphragm and creates a seal (due to the blocked force generated by the piezo). Creating the seal without excessive forces reduces the wear on the seal, allowing longer intervals between maintenance.
