A non-lethal dazzling device includes a laser operable in the visible spectrum. The laser can be a relatively low-powered laser, such as a laser having a maximum output power of 2.5 mW, or it can be a higher-powered laser with a drive circuit that lowers the maximum output power to a safe level based on the range of the hostile target from the laser. In certain embodiments, disclosed non-lethal dazzling device can be coupled to the bridge of a binocular device.

The present invention relates to an automotive vision system, in particular for providing rear and/or side view, comprising; an image capturing device, and an optical filter device included in an optical path to the image capturing device, wherein the optical filter device comprises an optical filter medium that is moveable by a driving device with respect to the optical path in order to adjust filter characteristics, wherein the driving device comprises a cam transmission that imposes a reciprocating movement on the optical filter medium over an adjustment range between two extreme positions and wherein the cam transmission has a stop arrangement defining an operative position of the optical filter medium with respect to the optical path, wherein the operative position is within the adjustment range and the operative position is in the vicinity of any of the two extreme position.

A prism and light transmitter module includes a prism holder, a light transmitter, a prism module, a drive circuit board, a shield, and a fixing assembly. The light transmitter is configured to emit or receive a light beam along a light axis. The prism module includes an inclined plane and is disposed within the prism holder with the inclined plane exposed. The drive circuit board is disposed above the inclined plane, and intersects with the light axis at a first angle. The shield is disposed on the drive circuit board. The fixing assembly connects to the prism holder, is configured to fix the drive circuit board, and includes a hole through which the light transmitter is exposed. A binocular capable of measuring distance includes a first optical system and a second optical system. The first optical system or/and the second optical system include the prism and light transmitter module.

A selectable fixed-focus binocular that is highly functional and simple to operate for the end consumers. The binocular combines the close and fine focusing advantages of a traditional binocular with the ease of use offered in a fixed-focus or focus-free style unit to make a versatile, user-selectable focus style binocular. The end-user can use the binocular in a typical, manual focus mode or manipulate the control knob to transition for use as a simple, fixed-focus unit.
