An electron beam detection apparatus includes a first aperture element including a first set of apertures. The apparatus includes a second aperture element including a second set of apertures. The second set of apertures is arranged in a pattern corresponding with the pattern of the first plurality of apertures. The detection apparatus includes an electron-photon conversion element configured to receive electrons of the electron beam transmitted through the first and second aperture elements. The electron-photon conversion element is configured to generate photons in response to the received electrons. The detection apparatus includes an optical assembly including one or more optical elements. The detection apparatus includes a detector assembly. The optical elements of the optical assembly are configured to direct the generated photons from the electron-photon conversion system to the detector assembly.

System for electron beam detection

Systems and methods for accurately measuring the luminous flux and color (spectra) from light-emitting devices are disclosed. An integrating sphere may be utilized to directly receive a first portion of light emitted by a light-emitting device through an opening defined on the integrating sphere. A light collector may be utilized to collect a second portion of light emitted by the light-emitting device and direct the second portion of light into the integrating sphere through the opening defined on the integrating sphere. A spectrometer may be utilized to measure at least one property of the first portion and the second portion of light received by the integrating sphere.

Light collection optics for measuring flux and spectrum from light-emitting devices

A method and apparatus for imaging features of a CBD in a patient introduces a fluorescent contrast agent into the CBD. A light source transmits both a visible light and a fluorescent light into a patient's abdominal cavity via the laparoscope. Cameras attached to or integrated into the laparoscope detect visible light images and fluorescent emission light images. The visible light image and fluorescent image signals are processed to combine the fluorescent emission light image signals and visible image signals into a single display signal. The system adjusts the display characteristics, such as color, of the fluorescent emission light image so it contrasts well with the visual light image so the surgeon can easily distinguish between the two images. The display signal is sent to a video monitor where the surgeon views the visible light image and the fluorescent image as a single overlaid image.

Common bile duct surgical imaging system

One embodiment relates to an apparatus for alignment measurement. A laser source generates an incident laser beam which is directed to a two-dimensional target grating on a target substrate such that multiple diffracted beams are created. A beam splitter transmits a first plurality of the multiple diffracted beams onto a first optical path and directs a second plurality of the multiple diffracted beams onto a second optical path. Each of the two optical paths includes a reference grating and a detector. Another embodiment relates to a method of measuring alignment of a target substrate. Other embodiments, aspects and features are also disclosed.

Alignment measurement system

A supporting structure is disclosed for both securing optical elements for providing optimal cooling of the optical elements and the light source.

Device and system for an optical element holder

A supporting structure is disclosed for both securing optical elements and for providing optimal cooling of the optical elements and the light source.
