Product Description

Trinocular Microscope 3.5X-90X Zoom

The SM-2T is a turnkey trinocular stereo microscope solution for biological and industrial fields. Using the workhorse SM745 head, it provides remarkable optical quality with a wide zoom magnification range. The dual-illumination base provides solid support, and both transmitted and reflected lighting for observing a range of objects, from biological cultures to PCBs. This trinocular model has an additional port for mounting a camera, so you can record video or photos without replacing an eyepiece.


The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. 10X wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. 0.5X and 2X Barlow lenses are included, which can be alternated to either halve or double the magnification range, expanding the possible magnifications to 3.5X-90X.

Ocular Adjustment

Dual ocular diopters can be adjusted to maintain consistent focus, greatly improving productivity. Rotating interpupillary adjusters simplify the process of aligning the eyepieces for each user.

Trinocular Port

The switched trinocular photo-port provides a dedicated mount for a camera. When the photo-port is switched open, all light from the left objective is diverted to the port to provide maximum brightness for the camera to guarantee the best quality images.

Dual-Illumination Stand

The dual-illumination stand provides a turnkey solution for biological and industrial applications. The pillar-based support system offers flexibility with its ability to quickly adjust height and lateral position. The microscope can be easily set and rotated in the mounting collar, and locked in place once adjusted. Large, symmetrical focus knobs provide the precision control needed, with adjustable tension for light or heavy loads as well as comfort.

Overhead and sub-stage halogen lighting allows you to work with opaque and translucent objects. The top light is mounted behind the head to provide offset light, and can be tilted for varied effect. This is useful for topological examination, such as with circuit boards and biological cultures. Thin tissue specimens, gemstones, and other translucent materials will benefit from the sub-stage transmitted lighting. A frosted glass stage-plate is provided to diffuse the light for more even back-lighting.
