The Ecoline Monocular Corded Microscope from National Optical is a four-objective optical instrument designed for university students and laboratory use. Equipped with achromatic objectives that minimize distortions and enhance clarity, it features a 100xR magnification objective.This microscope is easy to use, with a viewing head that rotates 360 . The 30 inclined eyepiece can be shared with multiple viewers without having to move the microscope. The separate fine and course focus adjustment dials enable quick focusing. The course focusing control has tension adjustment to prevent focus drift, while the fine focusing is graduated to bring specimens into tight focus. The microscope has a 3.4V, energy efficient 0.06W LED light source. The mechanical stage has low-position x-y specimen adjustment controls to accurately center slides.Optical System Achromatic lenses with color-coded objectives10x, 18mm eyepiece with pointer4x,10x, 40xR, and 100xR DIN objectives40x,100x, 400x, and 1000x magnification100xR enables oil immersion techniques360 rotating inclined head for easy eyepiece sharingFocusing Dual dioptersCoaxial low-position fine and coarse focusing controlsCourse focus with tension adjustment to prevent focus driftFine focus is graduated for precise image clarityRack stop prevents damage to slides and protects lensesLighting 3.4V 0.06WSwing-out frosted filter holderIris diaphragmBase mounted on/off switch with 4.5V DC auto switch power adapter (110V to 220V)Construction Details Low-position, built-in, ball-bearing mounted mechanical specimen holderMechanical stage with x-y specimen controlsCast aluminum body with gray enamel finishBall-bearing mounted 4-objective turret
