The 45° inclined viewing KETU17031C23 CoreScope 2 Binocular Microscope with Achromatic Objectives from Ken-A-Vision features a Siedentopf head, a mechanical stage, 4x, 10x, 40xS, a 100xS achromatic objectives, and a 360° rotating head. The retractable 40xS and 100xS objectives have spring-loaded lenses which will retract when it touches the slide in order to protect the lens and the slide. The 100xS objective ought to be used with immersion oil. Both the turret and the included objectives adhere to DIN microscope objective standard. This means that you can use any DIN objective with this microscope without worrying about your microscope ever becoming obsolete. With a wide field 10 x eyepiece, the microscope provides a total magnification of 40x, 100x, and 400x. The supplied achromatic objectives reduce color distortions introduced by imperfections in optical elements better than regular objectives and provide higher contrast images. The lenses are also coated with special coatings that protect their surfaces against mold in high humidity and high heat regions. The parfocalled and parcentered design allows for switching objectives without having to realign your sample and without losing focus. The focusing system has a coaxial coarse and fine focus adjustments with and a scale. To view details of our specimens more easily, the microscope features a white LED illumination system with adjustable brightness and an On-Off switch. The bright white light from the bottom LED emitter is collimated with a 1.25 NA Abbe condenser and can be regulated by a build-in iris diaphragm.
The microscope also features a coated 5.1 x 4.7" mechanical stage with two low position coaxial X-Y motion controls and a bracket for holding your specimen slides. The frame of the microscope is made of cast aluminum with a cream-colored enamel finish. Included with the microscope is a USB cable, a wall charger, three rechargeable AA batteries, and a dustcover.
