The T550 is designed to be an intermediate-level biological microscope for professional use or classrooms, with bright, high-efficiency LED illumination and precision ergonomic mechanics. The elegant modern look adds an aesthetic appeal to the functional design, with the trinocular Siedentopf viewing head, coaxial focusing system with tension control, and low-heat sub-stage lighting. The simul-focal CX series photo port allows for various optional camera mounts with a range of magnifications to accommodate any C-mount sensor-format. 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 left ocular tube 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 head uses a simul-focal optical system to project the image simultaneously to both eyepieces and the photo port without the need for any switching. The objective turret provides instant access to 4 magnification levels to easily focus in on minute details from 40X to 1000X. This covers magnifications needed for studying hair follicles, cells, 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. 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. LED sub-stage lighting provides bright illumination with high color-temperature for natural colors. The cool, energy-efficient lighting reduces heat for viewing live specimens, and provides high contrast for digital 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.
