Ken-A-Vision TU-19321C overview

  • 1Description

Ken-a-Vision designed the 110 VAC US version of their monocular-head configured TU-19321C Dual-Purpose Dual-View Microscope from the ground up as an ideal instrument for entry level to advanced science courses that is durable and student-friendly. Its dual-angled eyepiece head provides a more comfortable viewing experience for both users that non-angled heads are often unable to provide, and the entire head rotates a full 360° to facilitate sharing among groups. The two eyepieces are set directly opposite from each other eliminating interference, and each sees exactly what the other does - effectively reducing the required number of instruments by half, and allows instructors to accurately assess a student's knowledge and ability in real time.

The optical system features a head with dual 10x monocular eyepieces - one with an integrated pointer, and a four-objective 360° rotating turret with click-stop positions at each lens. Four objectives from 2x to 40x produce a broad magnification range of 20x to 400x making this microscope a versatile observation tool. Its achromatic glass objectives are designed to correct for chromatic and spherical aberrations in the center 60% of the field of view, so images have a true color representation with virtually no distortion at the central point of observation. If users need to change or replace objectives, Ken-a-Vision designed them to DIN standards to enable parts from many manufacturers to be installed without the need for modifications.

The microscope features a floating stage with spring-loaded specimen clips. A floating stage design provides for a larger working distance between the stage and objectives for examining larger subjects. Specimens are lit from below with an LED and an additional LED is set above the stage for use when observing solid or opaque specimens that require them to be lit from the top. The LEDs are powered by either the included power adapter or permanently installed rechargeable battery pack. There are two independent rheostats providing control of each LED intensity, and to help control the amount of light illuminating the specimen from below is a built-in condenser on the stage. This multifunction adjustability enables precise illumination for the perfect image.
