40X-2000X Trinocular Compound Darkfield Microscope w Oil Condenser

40X-2000X Trinocular Compound Darkfield Microscope w Oil Condenser

Availability: In stock
  • 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 an oil darkfield condenser. Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in refractive index.

The 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.

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 7 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 the 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 of oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field.  The condenser holder uses rack-and-opinion movement for precise height adjustment.  An oil darkfield condenser is included for darkfield observation using high-power objective lenses.  Darkfield observation will provide contrast in otherwise indistinguishable objects by highlighting changes in the refractive index.  This is particularly useful for observing live cells blood analysis.  The condenser is designed for use with immersion oil, and can accommodate medium and high magnification objectives.  Two centering screws allow you to properly center the condenser for optimal contrast.
