The D-ELDB Digital Compound Binocular Microscope from National Optical is a four-objective optical instrument designed for university students and laboratory use. It is equipped with achromatic objectives that minimize distortions and enhance clarity. The 100xR magnification objective can be oil-immersed for improved light transmission. This model features a built-in 3 megapixel digital camera. The camera connects to a computer through a 6' USB cable which also powers the camera. Using the included Motic Image software you can view live images, capture and save images, measure, edit, import & export images, and more.This microscope is designed for multiple users and has several features to make its use easy. The 360 rotating binocular viewing head enables the 30 inclined eyepiece to be shared with multiple viewers without having to move the microscope. Interpupillary and dual diopter adjustments allow different users to set the microscope for comfortable use.The focusing and illumination systems have been configured to make viewing specimens fast and easy. It has separate fine and coarse focus adjustment dials. The course focus has tension adjustment to prevent focus drift. The microscope also features a rheostat-controlled dimmer for the 0.06 watt LED light source. The mechanical stage has low-position x-y specimen adjustment controls to accurately center slides.Digital Imaging Built-in 3MP digital cameraConnect to a computer or laptop via included 6' USB 2.0 cable.Included Motic Images software enables live-viewing, image capture, measuring, editing, importing and exporting images, and more.Camera is powered by the USB cable.Optical System Achromatic lenses with color-coded objectives10x, 18mm eyepiece with pointerInterpupillary adjustment 50mm to 75mm4x,10x,40xR, 100xR DIN objectives40x, 100x, 400x, 1000x magnifications100xR enables oil immersion techniques360 rotating inclined head for easier eyepiece sharingFocusing Dual dioptersCoaxial low-position fine and coarse focusing controlsCourse focus has tension adjustment which prevents focus driftFine focus is graduated for precise image clarityRack stop prevents damage to slides and protects lensesLighting 0.06-watt LED with variable rheostat dimmerSwing-out frosted filter holderIris diaphragmBase mounted On/off switch with 4.5V DC auto switch power adapter (110V to 220V)Construction Details Mechanical stage with x-y specimen controlsCast aluminum body with gray enamel finishBall-bearing mounted 4-objective turretTurret is reverse mounted to make changing slides easier Specimen stage has coaxial x-y controls, is bulit-in and positioned low, with a low profile and ball-bearing mounted mechanical specimen holder
