This professional trinocular microscope is designed for teaching and clinical use. Its high quality optics and precision mechanics have made this model a favorite for veterinarians and clinics. It has a large compliment of optional accessories for darkfield, phase-contrast, and fluorescence. The trinocular head can be customized for each user, with a sliding interpupillary adjuster for varying eye spacing, and diopters for both eyes to fine-tune focus for nearsighted users and for asymmetry. The head can be rotated 360°, and has a 45° incline for viewing while seated or standing. Interchangeable eyepieces allow for an expanded magnification range, or the use of special eyepieces with pointers and measuring reticles. The trinocular photo port provides a dedicated mount for using a camera. The port is height-adjustable to match focus with the eyepieces, and does not require switching when used simultaneously with the eyepieces. The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stages low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level. The halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.
