Abstract:
Non-contact fluid deposition devices having multiple axis printhead adjusters are made up of a single rigid frame (100) that holds at least one printhead housing (200a), where in certain embodiments multiple printhead housings, e.g., two, are held in side-by-side configuration in the single rigid frame of the adjuster. Each housing (200a) is adjusted in said adjuster by its own set of axis adjustment elements (400), where the set includes a rotational axis adjustment element for each horizontal and/or vertical axis adjustment element that is present. In using the devices, a printhead present in the adjuster is loaded with a volume of fluid, which in many embodiments is a fluid that includes a biopolymer or precursor thereof. The loaded printhead is then placed in opposing relation to a surface of a substrate and actuated to deposit a volume of fluid on the substrate. Prior to fluid loading and/or deposition, the printhead is typically adjusted with the set of axis adjustment elements.
Abstract:
Planar optical waveguide apparatus and methods for fabricating planar optical waveguide apparatus. The apparatus has a core layer and a cladding layer, the core layer having at least one optical waveguide, and an alignment structure or marker spaced from and positioned with respect to the at least one optical waveguide to facilitate measuring a position of the at least one optical waveguide. The alignment structure has a first alignment structure, such as a reflecting member, to facilitate measuring a height of the at least one optical waveguide; and a second alignment structure, such as alignment marks, to facilitate measuring positions of the at least one optical waveguide in a plane of the at least one optical waveguide. The method includes forming both the optical waveguide and at least a portion of the alignment structure simultaneously in a single processing step, preferably by etching, to ensure that the optical waveguide and the alignment structure are in perfect registration.
Abstract:
A light source (11, 30, 40) having first and second wire-grid polarizers (63, 64) and a laser (31, 71) that emits a beam of linearly polarized light that is characterized by a propagation direction is disclosed. The first wire-grid polarization filter (63) is characterized by a first linear polarization pass direction and a first actuator (65) for causing the first linear polarization pass direction to rotate relative to the beam of linearly polarized light. The second wire-grid polarization filter (64) is characterized by a second linear polarization pass direction and a second actuator for causing the second linear polarization pass direction to rotate relative to the beam of linearly polarized light. A controller (29) sets the first and second linear polarization pass directions to provide linearly polarized light having a specified polarization direction.
Abstract:
The invention provides a mass spectrometry system ion source containing a sample plate and an illumination device that is configured to produce a light beam that contacts the sample plate surface to define a grazing angle between the light beam and the sample plate surface. The ion source may also contain an imaging device, e.g., a CCD or CMOS camera or the like, for viewing the area. In one embodiment, the imaging device may be connected to a display, e.g., a video monitor. Methods and mass spectrometry systems employing the ion source are also provided.

Abstract:
A method and apparatus for obtaining reference samples, i.e. measuring reference targets (62) on a reference stage (61) during the generation of a mid-infrared (MIR) image without requiring that a sample specimen (16), being placed on a specimen stage (57) and imaged, be removed is disclosed. A tunable MIR laser (11) generates a light beam (18) that is focused onto the sample specimen on the specimen stage that moves the specimen in a first direction (33). An optical assembly includes a scanning assembly (31) having a focusing lens (55) and a mirror (56) that moves in a second direction (32), different from the first direction, relative to the specimen stage. A light detector (13) measures an intensity of light leaving the point on the specimen. A controller (39) forms an image from the measured intensity. The reference stage (61) is positioned such that the scanning assembly moves over the reference stage in response to a command so that the controller can also make a reference measurement.

Abstract:
The invention provide an apparatus for producing an image of a global surface of an ion source sample plate (4) that is exterior to an ion source. In general terms, the apparatus contains a sample plate for an ion source, an imaging device (8) (e.g., a CCD or CMOS camera) and an illumination device (6) that is configured to produce a light beam (10) that contacts the sample plate surface to define a grazing angle (12) between the light beam and the sample plate surface. The light beam (10) may be reflected, diffracted or scattered as a light beam (14), at an angle (16) to the surface of the sample plate (4). The imaging device 8 may be at an angle (16) to the surface of the sample plate. The apparatus may be present at a location that is remote to the ion source.
