This trinocular compound microscope is designed for clinical examination and teaching demonstration in medical fields, veterinary offices, laboratories and colleges. The observation head has a 30° incline for comfort, and can swivel 360° for flexible viewing angle. The Siedentopf interpupillary adjustment allows easy fitting for any user. The 3D mechanical stage provides a wide range of movement, and is ergonomically designed for low-fatigue use. The variable-intensity LED illumination system provides a super-bright light source while maintaining a much lower temperature than halogen illumination. The trinocular port adds an additional port for a camera. The reversed objective turret is less obstructive than conventional forward turrets, and provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 25X eyepieces extend the maximum magnification to 2500X, and 6 distinct levels of magnification to cover a wide range of specimens. The high-quality lenses are achromatically corrected to improve resolution and color accuracy. This is an ideal instrument for schools, clinics, veterinarians, and general use. It offers a wide range of optional accessories to expand the functionality. The magnification range can be expanded with a large selection of objective and ocular lenses. Specialized condensers are available for dark-field and phase-contrast applications, ideal for bloodwork, fluid-analysis, and pathology.
