The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical limit.\u003c\/p\u003e\n\u003cp\u003eThe 490 series 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.\u003c\/p\u003e\n\u003cp\u003eTo customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain.\u003c\/p\u003e\n\u003cp\u003eThe objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. Additional 20X eyepieces expand the maximum magnification to 2000X with 8 unique levels. This covers magnifications needed for studying hair follicles, cells, and bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.\u003c\/p\u003e\n\u003cp\u003eThe 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's 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.\u003c\/p\u003e\n\u003cp\u003eLED sub-stage lighting provides bright illumination with high color-temperature for natural colors. The cool, energy-efficient lighting reduces heat for viewing live specimens, and provides high contrast for digital imaging. 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.\u003c\/p\u003e\n\u003cp\u003eThis kit includes 50 blank slides and 100 cover slips for dry or wet mounting specimens to view with your microscope.\u003c\/p\u003e\n\u003cdiv style=\"max-width: 800px;
