The NEW SZN-4T matches high-resolution optics with a brawny boom stand for demanding biological and industrial applications. The SZN series shows improvements in resolution, contrast, and distortion compared to our staple SM & ZM series. This model is especially popular in the manufacturing, QC, repair, and engraving industries thanks to its ease of use and reliability. This trinocular model has an additional port for mounting a camera, so you can record videos or photos without replacing an eyepiece. With its wide zoom range and double-arm boom stand, this model will become an indispensable instrument in any workshop or lab.
Enhanced features include the ability to set a minimum magnification level by locking the zoom knob, adjustable zoom click intensity, and a shutter pin to switch back and forth between binocular and trinocular modes.
Optics
The advanced optical system in the ZM series microscope produces higher resolutions throughout its zoom range, with stunning contrast and color accuracy. The 0.67X-4.5X objective lenses offer excellent focus depth and a large working distance, with symmetrical zoom knobs to easily move through magnifications. 10X and 25X eyepieces are included, as well as 0.3X and 2X Barlow lenses to provide an expanded magnification range from 2X-225X, with high-eyepoint optics to accommodate glasses or goggles.

Ocular Adjustment
Easy Adjustments for Any User
Dual ocular diopters can be adjusted to maintain a consistent focus, greatly improving productivity. Sliding interpupillary adjusters ensure each user can properly align the eyepieces for comfortable viewing.
Trinocular Port
A Dedicated Port for Imaging
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.
Double-arm Boom-Stand
Heavy-duty, Multi-pivoting Support
The multi-pivoting, double-arm stand provides a stable, flexible support system. A drop-down column allows the head to be positioned at virtually any angle. Ball bearings provide smooth movement of the lateral arms, which can easily pivot the microscope out of the way when it is unnecessary. The heavy, steel base ensures the stability of the microscope, even when laden with attachments.
