Photonics Engines for Fluorescence Detection The insight gained from the research on genes and proteins is having a revolutionary impact on medical diagnostics, pharmacology and food control. Luminescence and fluorescence are the preferred methods to capture the results of bio-chemical assays whether the sample format is a biochip, a microtiter plate, a capillary or a gel. Qioptiq accesses new solution paths in the diagnosis of hereditary diseases, virus detection and the development of pharmacological substances.
Development and Manufacturing Competency Over the recent years the company has become a first-class development and production partner of renowned appliance manufacturers in the fields of research and clinical diagnostics. Qioptiq co-developed a series of very successful measuring systems for fluorescence detection in the past years, which are an important contribution to basic molecular biology research.
Highly Efficient Optical Systems Each component of our systems is optimized to achieve the high efficiency which is required to detect the very weak signals of the fluorophores. Our optical systems are designed for maximum light capturing ability thus increasing sensitivity and throughput of your instrument. They provide a higher dynamic range accommodating for the vast differences in fluorophore concentration across the sample array and reduce cross-talk between sample spots through optimum optical resolution.

The simplest approach to detect the fluorescence emitted from a biological sample is to image the sample onto a camera. The advantages of an imaging solution are the fast image capture, the highly stable system, the real images of the biological sample, and the very low probability of false signals.
Excitation Light Source Design For the setup of the illumination assembly for fluorescence excitation we consider the appropriate
|
|
excitation spectrum, select the powerful light sources to excite the entire sample, create the high quality illumination optics for uniform distribution of the excitation light, minimize stray-light and ghost images, and select auto-fluorescence minimized components to reduce background noise through the entire system.
Efficient Fluorescence Detection We optimize the efficient collection and imaging of fluorescence light. Our optics systems combine a large detection lens aperture to increase light collecting efficiency, a vignetting-free optics to eliminate analysis errors near the edge of the sample, an excellent optical resolution to reduce the cross-talk between sample spots, optical blocking filters to keep excitation light away from the detector, and CCD sensors, that are perfectly adapted in resolution and sensitivity to transfer the image into digitized signals.
Data Acquisition Qioptiq is also your expert for the conversion of the collected photons to diagnostic data. We serve you with integrated detector solutions with high-dynamic-range analogue-to-digital conversion, noise suppression, bad pixel analysis and a digital interface to provide you with the most accurate test results.

Background Noise Reduction The dynamic range of imaging systems is often limited by electronic background noise. These applications require a more sensitive detector such as photomultipliers. The assays are analyzed by scanning the sample and sequentially reading the detector output to deliver digitized images.
Flexible Setup We tailor your custom scanning system to perfectly match your requirements. We integrate single
|
|
or multiple wavelength laser beams, variable beam expansion optics to allow to easy change of resolution and throughput, high aperture scan lens to capture the maximum of fluorescence light and thereby increase the system sensitivity. Background signal is removed by focusing the fluorescence light through a carefully adjusted pinhole. Appropriate dichroic mirrors and interference edge or notch filters suppress the fluorescent response from excitation illumination.
Scanning Principles For scanning the excitation beam over the sample you can either use galvomirrors to deflect the excitation light by before focusing with a flat-field scan lens or a laser collimating lens moving in two dimensions which laterally scans the laser spot across the sample.
