Sample support for use in recording unit during analyzing of hybridization reactions, has plano-convex cylinder lens provided for collimation and formation of laser band, which is irradiated through side surface in support

摘要

The support (6) has an illumination unit with a light source e.g. laser light source (1) having constant intensity, whose laser beam is radiated in the support by a side surface (7) of the support for forming an evanescent field, which occurs at a surface (19) and/or base surface (20). A beam diversification unit e.g. Powell lens (3), is arranged in an optical path (17) of the laser beam. A plano-convex cylinder lens (4) is provided for collimation and formation of a laser band (12), which is irradiated through the side surface in the support at a desired place.
