Edmund Optics offers a variety of Fresnel Lenses designed for visible or infrared applications. For maximum performance, the grooved side of a Fresnel Lens should face the longer conjugate. For example, when used with detectors, the grooved side should face away from the detector. Contoured lenses are available to improve focusing performance or spot size. Cylinder Fresnel Lenses are also available to focus in only a single dimension.

Phase contrast microscopy provides exquisite high-resolution images of sample morphology, without the use of sample labeling. However standard phase contrast techniques, like differential interference contrast (DIC), only work in the transmission direction and thus cannot be used when imaging thick samples. For this reason, standard phase contrast techniques have not made a great impact in in-vivo biomedical or clinical imaging applications.

Fresnel Lenses are used in many light collection applications, such as condenser systems or emitter/detector setups. Fresnel Lenses are optical lenses consisting of a series of concentric grooves etched into a plastic substrate. Each groove acts as an individual refracting surface, while the thin substrate minimizes the amount of light lost due to absorption. High groove density increases image quality, while low groove density increases the overall efficiency. Fresnel Lenses are typically not used as magnifier or projection lenses due to high levels of distortion.

We have developed a new technique, called Oblique Back-illumination Microscopy (OBM) that provides microscopic resolution DIC-like images of sub-surface sample morphology even in very thick tissue. In addition, OBM provides simultaneous amplitude imaging by a method of shadowcasting. Because OBM works in a reflected light geometry, it is amenable to endoscopy applications.

Two configurations of OBM are equivalent by reciprocity. The first is a camera-based configuration that uses standard widefield detection optics, but offset illumiantion optics. In the case of an endoscope, some extra relay optics is introduced in the detection path, such as an imaging fiber bundle. The second configuration (sOBM) is a laser-scanning-based configuration equipped with offset detection. This second configuration has the advantage that it can be combined with standard laser-scanning microscopes such as two-photon or coherent R15. Single-shot OBM video of chick embryo vasculature/OBM produces phase-gradient (left) and amplitude (right) contrast simultaneously. Single-shot operation is achieved by using two different illumination colors. Acquisition is video rate.aman microscopes, yield multi-contrast images that are automatically co-registered.
