摘要:
Disclosed are systems and methods for scoring and separating a glass sheet along a curved trajectory using a laser and optics. The system includes a laser that generates a laser beam, a focusing lens, and a conical optical component, such as a conical lens or a reflective conical mirror. The laser directs the laser beam through the focusing lens and conical lens to create a curved score line that is projected onto a glass sheet to create a curved score line, along which the glass sheet can be separated. Optionally, the laser directs the laser beam through the focusing lens towards a conical mirror, off of which the laser beam is reflected toward the glass sheet to create a curved score line.

The method and apparatus of the present invention achieves the trimming and therefore, tuning of fiber optic devices by, in one embodiment, precisely heating a small area (A) of a fiber to allow its elongation when mounted under tension in its package. By pulsing a source of heat (40) in precise amount, the elongation can be precisely controlled within 1 picometer precision over a tuning range of about 200 picometers. In another embodiment with fibers having core dopants which can be diffused, the optical length of an optical fiber can be trimmed with nanometer precision. By employing a controlled source of localized energy applied to the optical fiber, real time trimming can be achieved in both systems by injecting a broad band source of energy (30) at the input of the device and coupling a spectrum (32) at its output to monitor the frequency characteristic of the optical device during trimming.

Compound gain flattening filters of optical amplification include a series of filter components with spectral responses that are combined to approach a target loss spectrum. Small variations in the central wavelengths of the component responses can produce larg errors in the combined response of the compound gain flattening filter. However, the components can be divided into sub-components with balanced central wavelength deviations to achieve the desired response goals despite exhibiting otherwise detrimental wavelength deviations.

A cell culture apparatus may include a substrate defining a well. The well may define an interior surface, an exterior surface, an upper aperture and a nadir. The substrate may define a thickness between the interior and exterior surfaces that has a thickness proximate the nadir that is greater than or equal to a thickness proximate the upper aperture.

A compact microplate imaging system, including: a tunable light source; a lens ensemble to collimate the light source onto the microplate and to transmit light that is reflected from the microplate; a beam splitter to divert a portion of the reflected light; an imaging lens to collect diverted light and to produce an optical image of the at least one sensor of the microplate; and an image sensor for receiving the optical image of the at least one sensor of the microplate. A method for interrogating a sensor using the compact microplate imaging system, as further defined herein, is also disclosed.
摘要:
An optical splice joint and splicing process are provided for joining an end portion of a microstructured optical fiber (1) having a microstructure (5) formed from an array of holes (7), and a conventional optical fiber (3). The optical splice joint (27) is formed from a fused portion of opposing end portions (15, 17) of the microstructured optical fiber (1) and optical fiber (3), wherein the microstructured optical fiber (1) is surrounded by a jacket (9) that is at least 1.6 times thicker along its radius than the microstructure (5), and has a tensile strength of at least 30 Kpsi with an optical loss of less than 0.30 dB, and relatively little shrinkage (i.e., about 30%) of the holes (7) forming the microstructure (5). The splice joint (27) is formed by aligning end portions (15, 17) of the microstructured optical fiber (1) and the optical fiber (3), in a fusion splicer (18), and applying fusion heat to the fiber ends (25a, 25b) in a two step process with a low current arc (23) that is offset with respect to the end of the microstructured optical fiber (25a, 25b).

A swept wavelength imaging optical interrogation system (100) and a method for using the same to interrogate one or more biosensors (102) are described herein. The swept wavelength imaging optical interrogation system (100) is built upon a swept wavelength optical interrogation technology where a 2-D label free image is extracted from a series of high speed spectral images of the biosensor (s) (102) without the need of performing mechanical scanning.
