Abstract:
This detection device has a holder, light irradiation unit, angle adjustment unit, light receiving sensor, light receiving optical system, optical filter, and a control unit. The light receiving optical system guides light from a detection chip to the light receiving sensor. The optical filter is disposed in the light receiving optical system, blocks a part of plasmon scattered light, and passes, out of the light emitted from the detection chip, a part of the plasmon scattered light, and fluorescence emitted from a fluorescent material. The light receiving sensor detects the fluorescent light, and the part of the plasmon scattered light, which have been emitted from the detection chip and passed the optical filter. On the basis of the detection results of the plasmon scattered light, the control unit controls the angle adjustment unit, and adjusts the incident angle of the excitation light to a predetermined incident angle.

Abstract:
A ring light illuminator with annularly arranged light sources is disclosed. To each light source there corresponds a light collector, a homogenizing means for light from the light source, and an anamorphic system for imaging an output of the homogenizing means into an area to be illuminated. The anamorphic system compensates deformations of a cross-sectional area of a light beam in a surface to be illuminated due to an oblique angle of incidence of the light beam onto the surface. The homogenizing means in embodiments is a rod, into which light from the light collector is directed. The end of the rod opposite the light collector is imaged by the anamorphic system into the area to be illuminated on the surface. Also disclosed is a method for illumination.

Abstract:
A multisensor employs an optical system that is modified by the index of refraction of fluid passing between a light emitter and light detector to successfully distinguish between air and water (of any turbidity) and between water of different turbidity values. The optical system may employ lenses contacting the fluid to change their focal length and thus to focus and defocus light on the light detector depending on an index of refraction of the fluid.

Abstract:
An arrangement having a birefringent component is provided for use in spatial offset measurements and analysis systems. The birefringent optical arrangement provides different directional control of the excitation signal relative to the emission signal, so that offset between an excitation and emission location on a sample can be controlled for both or only one of the excitation signal relative to the emission signal.
