Product Core Features – What’s to Like?

AmScope SM-4TZ-144A

One of the professional features of AmScope SM-4TZ-144A that we like is that it enables you to work with large-scale objects.

It does not matter if you are a left or right handed, the bilateral focus on the stand eliminates that problem. The stand could also be pivoted out of the way when you do not need it, thanks to its lateral arms.

Does your work involve manipulation of large objects like computer motherboards, large artifacts? If so, this AmScope stereo microscope double-arm boom stand can help. It has a 20″ arms and 17″ pillar that will enable you to position the microscope head on three axes (X, Y, and Z.

With this 360° pivoting view head, no longer do you have to move the entire microscope back and forth for your fellow research colleagues. You can now conveniently swing the viewing head of the microscope to the colleague sitting beside you or opposite you. 🙂

Additional Barlow Lenses Extend Magnification Power to 90X

If making use of various magnification range forms part of your daily routine, you will be delighted to know that SM-4TZ-144A offers additional lenses that can be added onto various objective lenses.

You can choose to either increase the working distance by using the 0.5X Barlow lenses or power up magnification range with its 2.0X Barlow lenses.

Reflected Episcopic 4 Zones LED Light Bulbs

As we mention at the beginning, SM-4TZ-144A is for you if you need to adjust the intensity of your lighting on a regular basis while working on your specimens. You will fall in love with it’s removable 144-bulb LED ring light. Why? Because it comes with rheostat to help you control the light intensity as well as direction of the light.

This four zones (100,000-hour life span) LED ring light offers cool and shadow-free illumination. Perfect for people working with temperature sensitive objects.

Trinocular port Offers Photo/Video Capability

If you need to take footage or video of your specimen or object, you will come to appreciate the vertical trinocular port (23mm). It can either be used as a C-Mount or a mounting port for camera.
