AmScope T490A-DKO-IRIS T490 Series Darkfield Trinocular Compound Microscope 40X-1600X Magnification with 20W Halogen, Oil Condenser

T490 Series Simul-Focal Darkfield Trinocular Compound Microscope 40X-1600X Magnification with 20W Halogen, Oil Condenser, 100X IRIS Objective, and 3D Mechanical Stage

Key Features:

40X to 1600X magnification range for studying a range of specimens including hair follicles, cells, and bacteria. 10X and 16X 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 and a specialized 100X darkfield objective lens. 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 16X eyepieces expand the maximum magnification to 1600X 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.

An oil darkfield condenser and specialized 100X darkfield objective lens are included for darkfield observation. The condenser is designed for use with immersion oil, and can accommodate higher numerical-aperture lenses. Two centering screws allow you to properly center the condenser for optimal contrast. The 100X plan-achromatic lens has a built-in iris to adjust its numerical aprture for fine-tuning contrast. 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.
