Abstract:
A cartridge and cartridge system for use in an apparatus for analyzing a sample are provided. The system has a plurality of cartridges for different applications for a multimode instrument. The cartridges are removably engaged with a cartridge support of the apparatus in a “plug-in” format such that one cartridge may be removed from the apparatus and another cartridge may be easily installed. The cartridge support includes a plurality of cartridge positions that receive cartridges concurrently. One of the cartridges may be a luminescence cartridge that includes an integrated detector that is movable toward and away from a sample carrier of the apparatus, and thus toward and away from a sample located at the sample carrier.
Abstract:
A spectrometer including an entrance slit and the production of the entrance slit. The spectrometer includes a housing, an entrance slit, and an imaging diffraction grating inside the housing for splitting and imaging the light onto an optoelectric detector. The detector is arranged inside the housing. The housing and the base plate are connected to each other by mutually cooperating positioning members. The entrance slit, the positioning members of the base plate and the holding members for receiving and mounting the detecting device are integral parts of the base plate and are produced from the base plate in a precise manner, in a suitable form and in defined mutual positions by, for example, laser cutting or liquid jet cutting. The positioning members of the base plate and/or the holding members for the detecting device can be provided as resilient elements.
Abstract:
A spectrometer includes a micro-ring grating device having coaxially-aligned ring gratings for diffracting incident light onto a target focal point, a detection device for detecting light intensity, one or more actuators, and an adjustable aperture device defining a circular aperture. The aperture circumscribes a target focal point, and directs a light to the detection device. The aperture device is selectively adjustable using the actuators to select a portion of a frequency band for transmission to the detection device. A method of detecting intensity of a selected band of incident light includes directing incident light onto coaxially-aligned ring gratings of a micro-ring grating device, and diffracting the selected band onto a target focal point using the ring gratings. The method includes using an actuator to adjust an aperture device and pass a selected portion of the frequency band to a detection device for measuring the intensity of the selected portion.

Abstract:
We disclose apparatus that includes: (a) an enclosure including an aperture; (b) a prism mounted in the enclosure so that a surface of the prism is exposed through the aperture; (c) an optical assembly contained within the enclosure, the optical assembly including a radiation source and a radiation detector, the source being configured to direct radiation towards the prism and the detector being configured to detect radiation from the source reflected from the exposed surface of the prism; and (d) an electronic processor contained within the enclosure, the electronic processor being in communication with the detector. The apparatus can be configured so that, during operation, the electronic processor determines information about a sample placed in contact with the exposed surface of the prism based on radiation reflected from the exposed prism surface while it is in contact with the sample.
Abstract:
The spectroscopy module 1 is provided with a body portion 2 for transmitting light L1, L2, a spectroscopic portion 3 for dispersing light L1 made incident from the front plane 2a of the body portion 2 into the body portion 2 to reflect the light on the front plane 2a, a light detecting element 4 having a light detecting portion 41 for detecting the light L2 dispersed and reflected by the spectroscopic portion 3 and electrically connected to a wiring 9 formed on the front plane 2a of the body portion 2 by face-down bonding, and an underfill material 12 filled in the body portion 2 side of the light detecting element 4 to transmit the light L1, L2. The light detecting element 4 is provided with a light-passing hole 42 through which the light L1 advancing into the spectroscopic portion 3 passes, and a light incident opening 42a of the light-passing hole 42 is partially covered by a light transmitting plate 16.
Abstract:
A sensor for a spectrometer is provided, which includes at least one optical element onto which an excitation light source beam is directed and from which a target beam is emitted towards a sample to be analyzed. The at least one optical element can move, thereby enabling the direction of the target beam to be varied.
Abstract:
In a spectroscopy module 1, a light passing hole 50 through which a light L1 advancing to a spectroscopic portion 4 passes is formed in a light detecting element 5. Therefore, it is possible to prevent the relative positional relationship between the light passing hole 50 and a light detecting portion 5a of the light detecting element 5 from deviating. Moreover, the light detecting element 5 is bonded to a front plane 2a of a substrate 2 with an optical resin adhesive 63. Thus, it is possible to reduce a stress generated onto the light detecting element 5 due to a thermal expansion difference between the light detecting element 5 and the substrate 2. Additionally, on the light detecting element 5, a first pool portion 101 is formed so as to be located at least between the light detecting portion 5a and the light passing hole 50 when viewed from a direction substantially perpendicular to the front plane 2a. Thus, when the light detecting element 5 is attached to the substrate 2 via the optical resin adhesive 63, the optical resin adhesive 63 is pooled to remain at the first pool portion 101. Thus, the optical resin adhesive 63 is prevented from penetrating into the light passing hole 50.
Abstract:
A metal layer 13 made of Au or the like is formed on the upper surface of a transparent substrate 12. Dielectric layers 14a, 14b and 14c with different thicknesses are formed on the upper surface of the metal layer 13 (any one of the dielectric layers can have a thickness of 0) to form respective determination areas 15a, 15b and 15c. Further, different types of antibodies 22a, 22b and 22c are fixed on the upper surfaces of the respective dielectric layers 14a, 14b and 14c. Then, light is directed to the determination areas 15a, 15b and 15c, then signals of light reflected by the determination areas 15a, 15b and 15c are received, the light is dispersed, and analyses are performed on signals resulted from the light dispersion to detect the conditions of the surfaces of the respective determination areas, at the same time.
