Motic SMZ-143 LED Stereo Trinocular Microscope

Motic SMZ-143 LED Stereo Trinocular Microscope

Due to high demand and global product shortages due to the pandemic, please call for availability.

Motic SMZ140-LED and SMZ143-LED zoom stereo microscopes utilize a larger base post stand with lighted top and bottom using cool light LED illumination.

The built-in objective provides 1X - 4X zoom continuous magnification. The viewing head rotates 360°.

Eyepieces are inclined at 45°, have dual diopter adjustments, and afford interpupillary adjustment from 55mm to 75mm. All eypeices can accept a 23mm reticle. Includes a pair of widefield 10x eyepieces. Additionally, you may purchase paired wide field 5x, 15x, 20x, or 30x eyepieces.

The range of magnifications with the included objective lens:

  • 5x eyepieces: 5x - 20x
  • 10x eyepieces: 10x - 40x - included w/ microscope
  • 15x eyepieces: 15x - 60x
  • 20x eyepieces: 20x - 80x
  • 30x eyepieces: 30x - 120x
  • 5x, 15x, 20x and 30x eyepieces sold separately

Available in binocular or trinocular. This, the trinocular version, has a beam splitter which selectively directs 100% of the light to the eyepieces, or makes the right eye tube go dark and directs that light to the camera port.

The post stand has built-in top and bottom LED illuminators. Each illuminator has its own intensity control and each operates independently of the other. Includes two stage clips. Vertical post is 300mm (11.8") tall. Maximum specimen height with no auxiliary lens is 203mm (8").

Large dual focusing knobs feature a slip clutch to prevent damage to the mechanism. A tension adjustment eliminates focus 'drift'.

Top and bottom lights are both 3W LED with intensity control and separate on/off switches. Main power supply is 100V~240V.

This product is covered by 5-year warranty.
