Abstract: The present invention is directed to a device and a laser, eye-safe method for laser marking slides for use in conjunction with a light microscope. The device is an attachment for a light microscope that allows the operator to make marks on preparations of biological tissues or other materials placed on a glass slide or between a glass slide and a cover slip. The marks can be used to indicate or highlight a microscopic structure or feature of interest. The marking on the slide is performed as the specimen is examined, without having to remove it from the microscope stage. In this way the invention has application in a biomedical or pathology laboratory for diagnostic, research, archival, and teaching or training purposes.

Abstract: A laser line generator system that utilizes a light guide element to convert high energy coherent light generated by a high fill-factor laser diode bar into homogenous light, and utilizes one or more slow-axis relay lenses to image the homogenous light such that it forms a homogenous line illumination pattern on an illumination plane. The light guide utilizes parallel or down-tapered side walls to mix received coherent light in the slow-axis direction by way of total internal reflection. A Keplerian telescope including two cylinder lenses is optionally used in place of the slow-axis relay lens. Optional fast-axis lenses are used to assist in focusing the homogenous light at the illumination plane. The laser light generator forms, e.g., a single-pass imaging system for a scanning/printing apparatus in which the homogenous line illumination pattern is directed onto a linearly arranged series of spatial light modulators, such as Digital Micromirror Devices (DMDs).
