The disclosure relates to a viewing optic. In one embodiment, the disclosure relates to a viewing optic having an integrated display system. In one embodiment, the disclosure relates to a viewing optic having an integrated display system for generating images that are projected into the first focal plane of an optical system.

The invention is directed at a miniature grism system. The miniature grism system is a single compact device that comprises a grism with collimating and focusing optics. In an aspect, the grism includes at least one prism and a grating. In an aspect, the miniature grism system, and more specifically the grism, includes at least one prism which is placed on either side of the grating. The focusing optics and the collimating optics are found on opposite sides of the grism system, sandwiching the prism and grating of the grism. In an aspect, the miniature grism system is configured to be retained within a filter wheel. The miniature grism system is configured to be used with telescopes having a small focal ratio.

A satellite imaging system uses multiple cameras. For example, the incoming light from a telescope section of the satellite goes through a dichroic beam splitter, with the standard visible spectrum going to a first camera and wavelengths outside of the standard visible spectrum, such as in the infrared or coastal blue range, are sent to a second camera, allowing image data from multiple wavelength ranges to be captured simultaneously. The image data from the different wavelengths of the two cameras can then be selectively recombined. In a more general case, there is a first range of wavelengths and a second range of wavelengths.

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.

Whole eye optical coherence tomography (OCT) imaging systems and related methods are disclosed. According to an aspect, an OCT imaging system includes a source having an associated source arm path. Further, the OCT imaging system includes a reference arm coupled to the source arm. Further, the OCT imaging system includes a sample arm having an associated sample arm path and coupled to the source arm. The sample arm includes at least one optical component configured to simultaneously scan both an anterior and posterior portion of an eye of a subject.

An endoscope includes a four color separation prism having a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism which respectively separate light incident from an affected area into a blue, red and green color components, and an IR component, first, second, third and fourth color image sensors, and a signal output. The first color separation prism, the second color separation prism, the third color separation prism, and the fourth color separation prism are sequentially disposed from an object side when receiving the light incident from the affected area. The first color image sensor is disposed opposite to the second color image sensor and the third color image sensor across an incident ray which is incident vertically to an object side incident surface of the first color separation prism.
