B490/T490 family summary page
This is the 220V version of the T490B for use only in regions which support 220V.
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 photo-port provides a dedicated optical-path for imaging-solutions, with the ability to observe through all three ports simultaneously.
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.
