The T490-PCS ads phase-contrast to our hardest-working go-to microscope. A top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical q uality. 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. Upgraded with a modular phase-contrast system, new contrast-enhancement techniques are available for studying internal cellular structures and composite materials. To 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.The 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. 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. A phase-contrast kit is included, with three specialized objective lenses (10X, 40X, 100X) and a modular light condenser. Phase contrast is used to reveal detail in indistinct objects, such as unstained cells and microorganisms that would otherwise appear invisible. By using a combination of the specialized objective lenses and the modified light condenser, these invisible objects can be visualized by manipulating variations in phase. Show more
