GL Series Stereo Zoom

Delivers high quality image resolution with best in class zoom range

Incorporating advanced technology of Greenough optical design into a durable, cost effective microscope to provide crisp, clear images at all levels of it's 7:1 zoom ratio, 6.5X-45X on GL7 or 6:1 ratio, 10X-65X on GL6. Both series from Jenco deliver brilliant contrast, parfocality, flatness and depth of field. Accommodate even tall specimens thanks to the 4"/110mm working distance.

Abundant options and accessories help this dissecting scope adapt to your work space. Stands allow specimens to be viewed directly on the work bench or illuminated from above and below. Auxiliary lenses and eye pieces can increase or decrease both magnification and working distance/field of view.

​Ideal for biological sciences, dissections, geology, paleontology, food science, small device assembly or wherever gross observation of small detail is required, the GL Series will bring individual features to life.
• Save time - no need to refocus when zooming magnification, the GL Series is parfocal

• Minimize fatigue - flat field of view, side mounted zoom controls, low positioned focus control and 45° ocular incline all work together to reduce stress and allow work in a natural position

• Accommodate all users - wide interpupillary adjustment (45-75mm) and diopters in both high eye point eyepieces allow virtually all individuals comfort in viewing

​• Save Money for years to come – the cost effective GL Series will last beyond Jenco’s 5 Year limited warranty due to its all metal focus mechanism and quality optics


Jenco International's GL Series has a model to meet your needs

The Illuminated Stand is an all in one option, simply plug it in and observe opaque or transparent specimens with individual controls for reflected (upper 15W Halogen) and transmitted (lower 15W Halogen or 5W fluorescent) light. LED and fluorescent produce cool light for heat sensitive samples

Stereo Microscopes for Industry and Education
Observation of macro specimens is more enlightening with a Jenco ST-800 Series Stereo microscope.


  • Stage allows ample room for sample manipulation but still fits in a storage cabinet
  • ​ST-800 eye pieces are locked in the eye tubes and don't fall out or walk away
  • ​New Magnification Knob location, keeps hands clear of viewing area, replicates advanced scopes, ergonomic
  • Illuminated from three directions - above, below or both, observe opaque or transparent samples
  • Solid, all metal focusing mechanisms will endure high usage well beyond its five year warranty
  • Erect images don’t confuse the operator and the clear, 3D image is bright and flat.
  • They are parfocal so the image will stay in focus when switching magnification from low to high and back.


The new ST-800 Series two power stereos are more ergonomic because you select magnification by turning a knob located on the optical body as opposed to gripping the shroud, replicating a style used on higher priced stereos like the Jenco GL Series.
