Abstract:
An instrument includes a plurality of spaced-apart reaction regions (40) and a light source (10) comprising more than one individual light source. The light source is capable of illuminating more than one of the plurality of reaction regions with excitation beams (25). The individual light sources are arranged in groups and different groups of individual light sources are configured to emit different excitation frequencies. Each group of individual light sources is configured to provide excitation beams that illuminate one or more of the plurality of reaction regions simultaneously.
Abstract:
In one aspect, the invention provides an optical sensor comprising a flexible substrate and an optical element being positioned on the substrate. The flexible substrate comprises deformations affecting the optical element and the deformations are provided in a substrate deformation zone at least partly surrounding the optical element. It is an object of the present invention to provide an optical sensor configuration compatible with roll-to-roll manufacturing.
Abstract:
The invention relates to an arrangement for spatially resolved and wavelength-resolved detection of light radiation which is emitted from at least one OLED (1) or LED. A multilayer system (2), which is formed with layers configured on top of each other in an alternating manner made of a material with higher and lower optical refractive index n, is arranged between an electrode (3, 4), an OLED or LED and a substrate. In this case, light radiation from the at least one OLED or LED, comprising a plurality of different wavelengths λ1, ⋋2, ⋋3,...⋋n, exits the multi-layer system. Light radiation, comprising different wavelengths λ1, ⋋2, λ3,...⋋n with defined angles, exits, and is incident on at least one detector array (9, 9.1) after at least simple refraction on an optical element (10, 11) or after reflection on a layer or a layer system of a sensor (12), such that each light radiation comprising a wavelength λ1, ⋋2, ⋋3,... or ⋋n is incident on a detector element of the detector array. The detector elements of the detector array are arranged discretely in relation to one another.
Abstract:
An apparatus for differentiating multiple fluorescence signals by excitation wavelength comprises a plurality of reaction regions (10), a plurality of excitation light sources (16), a plurality of detectors (18), and a control unit. Each excitation light source is capable of providing a plurality of separate excitation beams, each excitation beam including a wavelength range that is not provided by the other excitation beams of the plurality of separate excitation beams, and each excitation light source is configured to direct each excitation beam along a beam path toward a single reaction region to which none of the other excitation light sources directs its excitation beams. Each detector detects emission beams emitted from a single reaction region. The control unit is configured to individually activate each of the plurality of excitation beams independently from activating the other ones of the plurality of excitation beams.
