AmScope T490 Series
Simul-Focal Biological Trinocular Compound Microscope 40X-2500X Magnification
Sku: T490C
Key Features
· The T490 is our
hardest-working, go-to microscope. The 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. The 490 series offers a
wide range of optional accessories to expand the functionality. The
magnification range can be expanded with a large selection of objective and
ocular lenses. Specialized condensers are available for dark-field and
phase-contrast applications, 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 25X eyepieces expand the maximum
magnification to 2500X with 6 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.
