40X-2000X Simul-Focal Darkfield Trinocular, Oil Condenser, 100X IRIS Objective, 3D Mechanical Stage

The T490-DK adds darkfield illumination to our hardest-working microscope. A top choice for veterinarians, breeders, & clinics, this instrument has proven reliability & optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, & a precision focus system with easy tension-adjustment & vertical-lock. The Simul-Focal trinocular head provides a dedicated photo port which can be used simultaneously with both eyepieces. with brightfield & darkfield illumination, this model is ideal for bloodwork, fluid-analysis, & pathology.

The 2-layer mechanical stage provides smooth & 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 & 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 & fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, & an iris diaphragm to optimize contrast & depth-of-field. The condenser holder uses rack-&-pinion 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 refractive index. This is particularly useful for observing live cells including blood analysis. The condenser is designed for use with immersion oil, & can accommodate medium & high magnification objectives. Two centering screws allow you to properly center the condenser for optimal contrast.
