{"product_id":"40x-2000x-trinocular-compound-darkfield-microscope","title":"AmScope T490B-DK 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\u003eA dry darkfield condenser is included for darkfield observation using the 40X objective lens or lower. 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. With a 0.9 numerical aperture, the condenser works with non-immersion lenses. Two centering screws allow you to properly center the condenser for optimal contrast.\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical
