Superb Depth of Field and Contrast

Benefits of all three GL Series Stereo Zoom Optical Bodies:

• Save time - no need to refocus when zooming magnification, the GL Series is parfocal and its continuous zoom is available with detentes at 0.5X increments for precise measurements
• Accommodate all users - wide interpupillary adjustment (45 - 75mm) and diopters built in to the eyepieces allow virtually all individuals to work in comfort
• Minimize fatigue - side mounted zoom controls and low positioned focus control with tension adjustment reduce stress and let the user rest in a natural position
• Save Money for years to come - high contrast, flat images are now cost effective and EMS's 5 year limited warranty protects your investment

The remarkably clear, non-distorted 3D image resolved by the GL Series optics is a result of advanced technologies in optical design. The GL Series Greenough design produces lifelike images in a large field of view and presents upright or erect images with astounding depth perception. A long (100mm) working distance facilitates observation.
