AmScope 40X-2000X Full-Size 17 Lbs Professional Trinocular Lab Biological Compound Microscope with 3D Two-Layer Mechanical Stage

• Three unique features: 1) Simultaneously views sharp clear images through the trinocular port and eyepieces; 2) Has both 23mm photo port and C-mount; 3) The Length of the trinocular port is adjustable
• Professional widefield optical system offers eight magnification settings 40X-80X-100X-200X-400X-800X-1000X-2000X
• Heavy-duty graduated 3D two-layer mechanical stage with coaxial coarse & fine focusing, rack & pinion adjusting Abbe condenser and iris diaphragm
• High quality intensity-variable halogen illumination system provides full spectrum light, giving the most colorful microscopy images
• Trinocular port uses the third port for camera capabilities, or a third party to view as well, giving you the remaining two ports to view your specimen

The T490B features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused clear images on your computer 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. In addition, the T490B's industry standard 23mm photo port can be converted into a C-Mount port, allowing you to attach most microscope digital cameras and video systems on the market. The T490B includes a 30-degree inclined 360-degree swiveling trinocular Siedentopf head, a 3-D mechanical stage, and an intensity-variable halogen illumination system. This versatile microscope is also capable of being upgraded with various accessories and attachments listed in the optional section for additional functions. It is a perfect laboratory instrument for clinics, Vets, Doctors, and professional students.
