359353000 | Including alternative optical path or optical element (e.g., day-night, hi-low magnification) | 8 |
20080231947 | Day/Night-Vision Device - In a day/night-vision device according to the invention, provision is made to view observations made via a day- or night-vision channel (T, N) in a shared receiving channel (E) or via an eyepiece unit ( | 09-25-2008 |
20080297885 | Dual band night vision device - A night vision device provides both an amplified visible light image and an infrared image, overlayed upon each other so that they appear to be a single image. A user may select to utilize either an intensified visual image only, an infrared image only, or ratios of both images simultaneously. Dichroic surfaces within the night vision device are utilized first to separate light into visible and infrared portions, and then to recombine the visible and infrared images to a single image. | 12-04-2008 |
20090122394 | Camera Module - A camera module according to an embodiment includes a lens barrel having a lens, a housing having an upper portion coupled with the lens barrel, a printed circuit board coupled to a lower portion of the housing and provided thereon with an image sensor and an infrared LED that emits infrared rays, and an infrared cut-off filter positioned above the lens barrel. The infrared cut-off filter is movable to inhibit the infrared rays from being incident into the lens barrel or to allow the infrared rays to be incident into the lens barrel. | 05-14-2009 |
20090168152 | Apparatus and Method for Deep Ultraviolet Optical Microscopy - An apparatus and method for performing optical microscopy are disclosed. In at least one embodiment, the apparatus includes a deep ultraviolet light source configured to generate light having a wavelength within a window in the deep ultraviolet region of the electromagnetic spectrum within which a local minimum in the absorption coefficient of Oxygen occurs. Further, the apparatus includes a lens device that receives at least a first portion of the generated light, directs at least some of the first portion of the generated light toward a location, receives reflected light from the location, and directs at least some of the reflected light toward a further location. Additionally, the apparatus includes a camera device that is positioned at one of the further location and an additional location, where the camera device receives at least a second portion of the reflected light, whereby an image is generated by the camera device. | 07-02-2009 |
20100079857 | LASER MICROSCOPE APPARATUS - Observation is performed using bright, clear multiphoton fluorescence images produced by efficiently generating a multiphoton excitation effect, without the need for a complex interference film structure. The invention employs a laser microscope apparatus including a first dichroic mirror that reflects visible laser light guided via a first light path and that transmits IR pulsed laser light guided via a second light path to combine the first light path and the second light path; an XY galvanometer mirror that scans the laser light from the first dichroic mirror on a specimen; an objective lens that irradiates the specimen with the scanned laser light and that collects fluorescence produced in the specimen; a second dichroic mirror that reflects the visible laser light and transmits the fluorescence from the specimen; and a detection unit that detects the fluorescence transmitted through the second dichroic mirror. | 04-01-2010 |
20100103508 | Combined day and night weapon sight - A combination day/night sight includes an image intensifying sensor/display combination and a daytime optical path length compensator that may be selectively placed within the optical path. Use of the optical path length compensator when the image intensifying sensor/display is not being used eliminates the need for moving optical elements. The night sight therefore requires no change in focus or bore sight adjustment after switching between day and night operations. | 04-29-2010 |
20100134878 | LENS MODULE WITH INFRARED-CUT FILTER AND INFRARED-PASS FILTER - An exemplary lens module includes a barrel receiving a lens system therein, an infrared-cut filter, an infrared-pass filter, and a switching mechanism. The switching mechanism includes a connecting member interconnecting the infrared-cut filter and the infrared-pass filter, a first magnetic member fixed at the barrel, and a second magnetic member fixed at the connecting member. The first and second magnetic members are configured for driving the connecting member to move relative to the barrel so as to selectively bring either the infrared-cut filter or the infrared-pass filter into optical alignment with the lens system in the barrel. | 06-03-2010 |
20120120482 | MODULAR DAY MODE/NIGHT MODE HELMENT-MOUNTED DISPLAY - A helmet mounted display (HMD) system comprising (i) a display device adapted to be positioned between an eye of a person wearing the helmet and a vision-related device; and (ii) a step-in visor which is positioned between the eye of the user and the display device. The vision-related device is removably attached to an accessory joint so that it can be interchanged between an outer visor for use during the day and night vision goggles for use during the night. | 05-17-2012 |
