A wavebeam guide transmitting the laser emission to a selected region of a patient comprises only two mirrors; an input mirror and a output mirror, which mirrors are mounted in units of the device connected by a telescopic shaft. The input mirror is mounted so that it can rotate about an axis coinciding with the axis of the laser beam falling thereupon and about an axis perpendicular thereto. The output mirror can also rotate about the axis of the laser beam falling thereon and about the perpendicular axis. Both mirrors can also rotate together in relation to the axes of rotation of the input mirror and the distance between the mirrors can be changed by means of the telescopic shaft. An aiming grip is provided to carry a focusing lens mounted so that it can rotate about the axis of the laser beam reflected by the output mirror.

The technology generally relates to a binocular having two tubes, which are connected to one another by means of a hinged bridge pivotable about a hinge axis for adjusting the interpupillary distance. Within each of the two tubes a beam path is formed with a first optical axis of an objective lens, with a second optical axis of an eyepiece and with a prism erecting system, characterized in that the first optical axis of the objective lens and the second optical axis of the eyepiece are offset parallel to each other by a distance.

A periscope includes an object window 4, a first reflector 5, a second reflector 6; and an intermediate port between the first reflector 5 and the second reflector 6. The first reflector 5 is arranged to reflect light from the object window 4 towards the second reflector 6 through the intermediate port. The second reflector 6 is selectively movable between a first position of use in which the second reflector 6 reflects light from the first reflector 5 towards a viewing position and a second position of use in which the second reflector 6 closes the intermediate port.

An unobscured afocal three-mirror telescope can provide a two-axis gimbal architecture that is more compact, more lightweight, and less expensive than traditional coudé path approaches. The telescope can create a real exit pupil and position the exit pupil on a 90-degree fold mirror. Two orthogonal rotational axes can intersect substantially at or about the center of the telescope's exit pupil and on or about the center of the last fold mirror.

An image blur correction apparatus includes a lens unit configured to include at least one lens, and configured to be turnable in two different directions using, as supporting points, two axes that are orthogonal to an outer housing. The image blur correction apparatus also includes a fixed member configured to turnably support the lens unit in the two directions, a first drive unit configured to be attached to the fixed member, and configured to turn the lens unit in one of the two directions. The image blur correction apparatus further includes a second drive unit configured to be attached to the fixed member, and configured to turn the lens unit in another of the two directions.

A solar light distribution system includes a solar light concentrator that is affixed externally to a light transfer tube. Solar light waves are processed by the concentrator into a collimated beam of light, which is then transferred through a light receiving port and into the light transfer tube. A reflector directs the collimated beam of light through the tube to a light distribution port. The interior surface of the light transfer tube is highly reflective so that the light transfers through the tube with minimal losses. An interchangeable luminaire is attached to the light distribution port and distributes light inside of a structure. A sun tracking device rotates the concentrator and the light transfer tube to optimize the receiving of solar light by the concentrator throughout the day. The system provides interior lighting, uses only renewable energy sources, and releases no carbon dioxide emissions into the atmosphere.
