A compact integrated optical system including an eyepiece, a reflective telescope, and a multi-spectral combiner optically coupled between the reflective telescope and the eyepiece, and configured to direct visible light received via the reflective telescope assembly along a direct view optical path to the eyepiece assembly. In one example, the multi-spectral combiner includes a display that displays a visual representation of the imagery of the viewed scene, and laser range-finder transceiver that transmits and receives a laser beam via the reflective telescope. A pair of beamsplitters is used to separate the imaging optical path from the direct view and laser range-finding optical paths. A blocking device is used to enable laser range-finding capability during daytime viewing of the imaging optical path imagery on the display. The reflective telescope provides a common aperture for the direct view optical path, an imaging optical path, and the laser range-finder transceiver.

An optical device includes a digital visual data system, a forward optical assembly, and an elevation manual adjustment and a windage manual adjustment. The elevation manual adjustment and the windage manual adjustment are configured to adjust a position of a movable optical assembly containing an optical merging assembly independently moveable in relation to the forward optical assembly. The optical merging assembly includes a first wedge-shaped component receiving optical data from the forward optical assembly and a second wedge-shaped component adjacent to the first wedge-shaped component that receives and transmits the optical data from the first wedge-shaped component through the second wedge-shaped component toward an eyepiece assembly and that reflects digital visual data from a micro-display toward the eyepiece assembly to present a merged data view when viewed through the eyepiece assembly.

A ranging telescope includes an object lens unit, an image turning module, an eyepiece unit and a display. Ambient light passes through the object lens unit, the image turning module and the eyepiece unit to form an ambient light path. The display is configured to generate display light which passes through the image turning module and then through the eyepiece unit. The light flux regulator is disposed in the ambient light path and between the object lens unit and the eyepiece unit, for regulating flux of the ambient light or the display light that passes through the eyepiece unit, so as to regulate an intensity difference between the ambient light and the display light passing through the eyepiece unit.

There is provided an endoscope system in which a depth of field is widened, and which is capable of acquiring a high-quality image with an aberration corrected favorably.

The endoscope system includes an objective optical system OBL, an optical path splitting unit which splits an object image acquired by the objective optical system OBL into two optical images having a different focus, an image pickup element which acquires the optical images, and an image synthesis processing section which selects in a predetermined area an image with a relatively high contrast from the two optical images acquired, and generates a composite image, wherein the objective optical system OBL includes a first lens L1 having a negative refractive power which is nearest to object, and the endoscope system satisfies the following conditional expressions (1) and (2).

3<D_diff/im_pitch100(1)

0.005<D_diff/R1_r<1.0(2) where, D_diff denotes an air conversion length of a difference in length of optical paths of the two optical images, im_pitch denotes a pixel pitch of the image pickup element, and R1_r denotes a radius of curvature at an image-side surface of the first lens having a negative refractive power.
