The T590 is a mid-level trinocular compound microscope with scalable features to accommodate growing labs and classrooms. The heavy-duty design will hold up to years of hard use, and is supported by a large set of accessories including epi-fluorescence, phase-contrast and darkfield kits. This instrument is ideal for scaling laboratories and scholastic demonstrations.
The microscope's head is uses a trinocular designed, with a binocular viewing platform and a third port intended for mounting a camera. Siedentopf interpupillary adjustment allows any user to easily align the oculars for comfortable viewing. For users with astigmatism or asymmetrical vision, the right ocular has dioptric adjustment to fine-tune focus. The switched trinocular port provides a dedicated mount for a camera to record photos or videos, and is height-adjustable to match focus with the eyepieces. The ocular tubes are set to a 30° incline, and can be rotated 360° to accommodate viewing from various positions.
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.
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 or 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. A swing-out filter holder can be used to mount a color filter for band-isolation or to change the light's hue. The condenser holder uses rack-and-pinion movement for precise height adjustment.
