{"product_id":"40x-2000x-trinocular-compound-darkfield-microscope-with-oil-condenser","title":"AmScope T490B-DKO-IRIS Trinocular Biological Microscope with 2000X Magnification and 20W Incandescent Light Source 3D Mechanical Stage","description":"\u003cp\u003eThe T490-DK adds darkfield illumination to our hardest-working microscope. A 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-lock. The simul-focal trinocular head provides a dedicated photo port which can be used simultaneously with both eyepieces. With brightfield and darkfield illumination, this model is 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 the both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain. The 23mm photo port is height-adjustable to match focus with the eyepieces, and can be replaced with an optional CX series C-mount port which have built-in reduction, and can directly interface with C-mount cameras.\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. LED 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\u003eAn \u003cb\u003eoil darkfield condenser and specialized 100X darkfield objective lens\u003c\/b\u003e are included for darkfield observation. The condenser is designed for use with immersion oil, and can accommodate higher numerical-aperture lenses. Two centering screws allow you to properly center the condenser for optimal contrast. The 100X plan-achromatic lens has a built-in iris to adjust its numerical aperture for fine-tuning contrast. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index. This is particularly useful for observing live cells including blood analysis.\u003c\/p\u003e\n\u003cdiv style=\"max-width: 800px; text-align: left;\"\u003e\n\u003ch3 style=\"padding: 0.5em 0; margin: 0;\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"vertical-align: top;
