20080259449 | Telescope and Panfocal Telescope Comprising Planoconvex or Planoconcave Lens and Deflecting Means Connected Thereto - The invention relates to a telescope which is used to inject and/or to extract, by reflection, emitting and/or capturing bundles of beams. According to the invention, at least one deflecting means is joined to the planar surface by means of at least one lens of the telescope objective unit, which is embodied as a plan convex or plan concave lens. The lens is used as a lens of the objective unit and as a holder for the deflection means. The number of optical components in the telescope about one of the holders is reduced due to the dual function thereof. | 10-23-2008 |
20090080070 | Imaging System Having Enhanced Resolution - Systems and methods for imaging a distant light source at an enhanced resolution is provided. An evanescent field generator an evanescent field generator that receives an incident electromagnetic field representing at least one distant light source and restores high spatial frequency components to the incident electromagnetic field, resulting in an evanescent field. A negative refractive index lens assembly focuses the evanescent field onto a focal plane. A photodetector assembly located in the focal plane detects the focused evanescent field as an image of the at least one distant light source. | 03-26-2009 |
20090109528 | Top Angle focus scope - A rifle scope has a front end receiving light and a rear end passing light to the user eye. The rifle scope has an elevation adjustment; an inside body is hollow and tubular and fitting inside a middle body which is also hollow and tubular shaped and a top angle focus adjustment mounted on the inside body in front of the elevation windage. The top angle focus adjustment has a top angle focus knob, a focus shaft mounted to the focus knob, and a top angle gear mounted to the focus shaft. The top angle focus knob and the focus shaft and the top angle gear are fixed so that they rotate together on an axis of the focus shaft. The inside body focus gear housing has an inside body focus gear meshing with the top angle gear, and the top angle gear rotation rotates the inside body focus gear. | 04-30-2009 |
20100214655 | Telescopic device capable of rapidly switching eyepieces - A multi-functional telescopic device is disclosed which can be used as an optical telescope for general long-distance observation and astronomical observation or as a magnifying glass. More particularly, the telescopic device allows for rapidly switching a terminal eyepiece between long-distance observation and a horizontal eyepiece for astronomical observation. The telescopic device is characterized in that a rapidly switching reflective mirror is provided to an end of the terminal eyepiece and the horizontal eyepiece, so that a user can directly rotate an external switching knob to selectively switch the terminal eyepiece and the horizontal eyepiece. As a result, the user can not only observe remote objects conveniently, but also watch the stars directly through the horizontal eyepiece without having to look upwards at a large elevation angle. | 08-26-2010 |
20110255158 | FOCUSING MODULE FOR LONG FOCAL LENGTH TELESCOPE - A focusing module for long focal length telescope is disclosed. The focusing module comprises a sliding plate, a fixing sleeve, and a fixing blot. The drawtube is disposed on the sliding plate for sliding forward or backward to focus. The fixing sleeve and the fixing blot form a connecting mechanism. When screwing the fixing sleeve to clamp the sliding plate from the bottom, the fixing bolt will be driven to clamp the sliding plate from the top simultaneously. This prevents the main tube and the drawtube from being displaced, and the target can be kept in the field of view of the telescope. | 10-20-2011 |
20130329286 | METHOD AND DEVICE FOR CORRECTING THE THERMOELASTIC EFFECTS, NOTABLY FOR A SPACE TELESCOPE, AND TELESCOPE COMPRISING SUCH A DEVICE - A method for correcting the thermoelastic effects on performance parameters of a telescope on board a space satellite, comprises a first step prior to the flight of the satellite consisting in determining, a priori, a correction of the thermoelastic effects by using a prior model of variations of the thermoelastic effects on the orbital scale and an algorithm for determining correction fed by programming data of the space satellite, and a second step carried out in flight, based on the correction determined a priori, consisting in establishing control messages of correction means for correcting the performance parameters of said telescope. | 12-12-2013 |
20140111852 | TELESCOPE WITH IMPROVED FORCE TRANSMISSION PATH - A telescope having an axially movable optical assembly, in particular, a focusing device and an adjustment device for actuating the optical assembly. A force transmission path from the adjustment device to the optical assembly is formed at least partially by a multitude of force transmission elements arranged abutting on one another in a force transmission channel. | 04-24-2014 |
20140160561 | ADJUSTING DEVICE ON AN OPTICAL INSTRUMENT - An adjusting device for linearly displacing an assembly has a rotary knob rotatable in first and second rotary directions. A gear unit rapidly displaces the assembly in a first linear direction when the rotary knob is rotated in the first rotary direction and slowly displaces the assembly in a second linear direction opposite the first linear direction when the rotary knob is rotated in the second rotary direction over a defined rotation angle. | 06-12-2014 |
20150015945 | ELECTRONICALLY ADJUSTABLE LONG-RANGE OPTICAL DEVICE - A long-range optical apparatus includes an optical unit defined by lenses and an eyepiece and has at least one manually operable adjusting device for adjusting an optical unit defined by the lenses. With the adjusting device, the optical unit can be adjusted relative to a mounting device. The adjusting device is mechanically coupled to at least one optical element or the mounting device. The optical apparatus has an electronic unit including a memory and the electronic unit performs an electronic function in dependence upon a setting parameter stored in the memory. The adjusting device is coupled with a position detection unit so that actuation of the adjusting device triggers an electrical signal of the position detection unit as a function of the position of the adjusting device. The electronic unit stores or changes a setting parameter in the memory in response to the electrical signal of the position detection unit. | 01-15-2015 |
20160004073 | GEODETIC INSTRUMENT WITH DIFFRACTIVE OPTICAL ELEMENTS - The invention relates to a geodetic instrument, in particular a geodetic telescope, for example for a theodolite, or geodetic overview, photogrammetry or axial camera, comprising an imaging optical system which defines an optical axis and comprises an observation beam path for imaging a target object by an eyepiece and/or on a camera sensor, for registering and/or providing an image of the sighted target object. According to the invention, the imaging optical system comprises at least two diffractive optical elements in the observation beam path. | 01-07-2016 |

The target mark is positioned in the beam path between the eyepiece and the objective and the target mark and the eyepiece are supported by a first body and the objective is supported by a second body. Either the first body or second body has two annular recesses spaced apart from each other along the beam path and disposed coaxially with respect to the beam path. Each of the annular recesses accommodates a ring. The other body has at least sectionally a cylindrical outer surface extending coaxially through the two annular recesses and rings along the beam path and is guided by the ring such that the distance between the eyepiece and the objective is adjustable by moving the first body and the second body relative to one other along the beam path. | 11-15-2012 |
