The Dino-Lite AM4113T Pro USB Microscope represents the latest version of the Dino-Lite AM413T which was without doubt the most popular model in the Dino-Lite Pro range. This latest reincarnation still offers 1.3MP image resolution but uses the very latest image sensor bringing with it improved colour rendering and low light performance. The new housing with magnification lock feature and improved thumbwheel action further enhance the product. Other than this the AM4113T inherits all other attributes from the AM413T and offers professional users crystal clear images combined with access to advanced software features. The 1.3MP image sensor provides excellent full screen resolution and the standard working distance optics (10x-60x & 200x) offer a wide range of magnifications for general use (10x-60x & 200x-240x). Advanced software measurement features with calibration and the MicroTouch snapshot function also feature as standard on the Dino-Lite Pro AM4113T.Technician Specifications:Resolution: 1280 x 1024 pixels(1.3MP)Magnification:10x ~ 70x 200xWorking Distance: StandardInterface: USB 2.0Number of LEDs: 8LED on/off switchable: YesLED colour: WhiteMaterial: CompositeExchangeable caps: NoMicrotouch: YesScroll lock: YesOutput: Picture Video Time-lapsed videoVideo Frame Rate: Up to 30 frames-per-second 15fps at 1.3MPMeasurement: YesCalibration: YesFilter/Diffuser: NoneCompatibility: Windows XP Vista 7 8 & 10 MacOS 10.9 +Software: DinoCapture for Windows DinoXcope for MacOSJPEG Codec: NoneDimensions: (L) 105mm x (H) 32mmField of View Specifications:(WD = working distance FOV = field of view)Magnification rates:20: 48.7mm (WD) 19.8mm (FOV:x) 14.9mm (FOV:y)30: 21.7mm (WD) 13.2mm (FOV:x) 9.9mm (FOV:y)40: 9.0mm (WD) 9.9mm (FOV:x) 7.4mm (FOV:y)50: 1.9mm (WD) 7.9mm (FOV:x) 5.9mm (FOV:y)60: -2.3mm (WD) 6.6mm (FOV:x) 5.0mm (FOV:y)220: -0.1mm (WD) 1.8mm (FOV:x) 1.4mm (FOV:y)230: 1.0mm (WD) 1.7mm (FOV:x) 1.3mm (FOV:y)240: 2.1mm (WD) 1.7mm (FOV:x) 1.2mm (FOV:y)
