Key Features

  • 40X to 2000X magnification range for studying a range of specimens including hair follicles, cells, and bacteria. 10X and 20X eyepieces provide 8 unique magnification settings.
  • A top choice for veterinarians, clinics, and classrooms, this microscope provides high quality optics and precision mechanics.
  • Professional features include a Siedentopf trinocular head for precise adjustments, a 2-layer mechanical stage with low-position controls, and coaxial coarse and fine focus for ergonomics and an efficient workflow.
  • Halogen lighting reduces eye-strain for prolonged use.
  • The trinocular photo port allows you to easily mount a camera. The T490 is compatible with our CX series C-mount photo ports with built-in reduction.
  • Includes a phase-contrast kit for live-cell studies. The kit includes 4 plan-achromatic phase-ring equipped objective lenses and a 5-position turret condenser.
  • Includes 5MP microscope camera

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 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. Upgraded with a phase-contrast system, new contrast-enhancement techniques are available for studying internal cellular structures and composite materials. A 5-position turret condenser provides easy access to brightfield and multiple phase-contrast settings with the turn of a dial.

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 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.

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 a 5-position turret condenser and 4 plan-achromatic phase-contrast objective lenses. 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 specialized objective lenses and a modified light condenser, these invisible objects can be visualized by manipulating variations in phase. This turret condenser allows you to easily rotate through the brightfield and four phase-contrast settings (10X, 20X, 40X, 100X). Each phase-contrast setting has a centerable annulus for proper alignment. Each of the phase-ring equipped objective lenses has plan-achromatic corrections for improved color and resolution, as well as edge-to-edge sharpness.
