AmScope, T440QB, 40X-2000X Advanced Student Compound Microscope with Trinocular Head
Features
- Eight widefield magnification levels from 40X to 2000X
- Professional 30 degree inclined 360 degree swiveling Siedentopf trinocular head
- Large 3-D double layer mechanical stage with coaxial coarse & fine focusing
- High quality Abbe condenser with iris diaphragm
- Centerable field-diaphragm for high-contrast Koehler illumination
With the same ergonomic, intuitive design of the 440 Series, the 440Q adds a fifth objective lens, and higher-contrast Koehler illumination for refined control. These improvements make the microscope more appropriate for medical practices and higher education.
The quintuple objective turret provides instant access to 5 magnification levels to easily focus in on minute details from 40X to 1000X when used with the 10X eyepieces. Additional 20X eyepieces extend the maximum magnification to 2000X, and 8 distinct levels of magnification to cover a wide range of specimens. The high-quality lenses are achromatically corrected to improve resolution and color accuracy. Aplanatic corrections improve edge-to-edge sharpness across the entire field of view.
For viewing comfort, the oculars are angled at 30°, and use compensation-free Siedentopf interpupillary adjustment. The head can be rotated 360° for variable viewing angles. For imaging, the head uses a trinocular profile, with a top-mounted photo port for stability. The standard 23mm mount can be used with virtually any microscope cameras on the market, supporting a range of reduction lenses, and relay lenses for SLRs.
Coaxial focusing and stage movements are strategically placed to be highly intuitive while viewing specimens. The daylight-balanced LED, and high-numerical-aperture Abbe condenser provide high resolution illumination with natural colors. The addition of a centerable field diaphragm in the illuminator allows for better light-control and higher contrast.
