This phase-contrast microscopy system includes a T490B trinocular microscope and a phase-contrast kit with a multi-position turret. It is a perfect laboratory instrument for clinics, vets, doctors, and professional students.
The T490B features a "simul-focal" optical system with an adjustable trinocular port to enable well-focused, clear images on your PC or video screen while simultaneously obtaining sharp, focused images through the eyepieces. Most trinocular microscopes allow you to view either through the trinocular port or the eyepieces only, forcing you to switch between the two. Since these trinocular ports are not "simul-focal" with the rest of the microscope optical system, you have to re-focus the microscope after each switch. The T490B, however, erases this step by providing "simul-focal" viewing. Especially handy for teaching demonstrations, clinical examinations and laboratory applications, the "simul-focal" feature allows your students or colleagues to view clear images simultaneously while you work through the eyepieces.
The T490B includes a 30-degree inclined 360-degree swiveling, compensation-free trinocular head, a 3-D mechanical stage, and an intensity-variable halogen illumination system. The phase-contrast kit is complete, coming with a phase-contrast turret condenser with iris diaphragm, a CT lens, and a set of phase contrast 10x, 20x, 40x and 100x plan objectives. The 1.25NA turret condenser includes open bright field position, and 4 phase-contrast positions.
