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
