Amscope 40X-1000X Quintuple Plan Infinity Kohler Laboratory Trinocular Compound LED Microscope

Sku: T720Q

Key Features

  • The infinity-corrected optical system reduces distortion and improves color accuracy.

  • The quintuple lens turret is equipped with five plan-achromatic objective lenses producing high-contrast images with edge-to-edge sharpness.

  • The Koehler illumination system provides centered, evenly-distributed lighting with a field aperture for maximum contrast and definition.

  • Rackless mechanical stage provides extremely smooth movement over a wide range.

The T720Q is an economical microscope designed for professional biological applications. Its infinity-corrected optical system ensures reliable, low-distortion magnification, with plan-achromatic corrections for accurate colors, excellent field flatness and edge-to-edge sharpness. A quintuple lens-turret is used, providing five levels of magnification. The Koehler-design LED illumination system provides bright, evenly-distributed light for maximum contrast and definition. This model is a popular choice for veterinarians and university laboratories.

The trinocular head accommodates simultaneous viewing through both eyepieces and the top-mounted photo port. The binocular viewing tubes use Siedentopf adjustment to easily fit any user. Focusable eyepieces are used to compensate for users with astigmatism or asymmetrical sight. For mounting a camera, the photo port provides a 23mm tube and a C-mount adapter for use with most microscopy imaging systems available.

The quintuple objective turret provides instant access to 5 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, soil, and bacteria. The turret's reversed orientation provides more working room above the stage. These high-quality lenses are achromatically corrected to improve resolution and color accuracy, with planatic flat-field correction to provide edge-to-edge sharpness.

The large 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The rackless design provides a wide range of movement without the obtrusive, exposed teeth of conventional mechanical stages. 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.

Built on Koehler illumination principals, the sub-stage lighting provides evenly-distributed light for optimal contrast. The LED light-source ensures cool, energy-efficient illumination with low heat for live specimens. The bright light-source is daylight-balanced to produce natural colors for imaging. 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 height adjustment for precision control, and is centerable for proper alignment. The illuminator's field lens provides an iris diaphragm to control light-spread, optimizing contrast and definition in specimen features.
