This advanced trinocular polarizing microscope is an advanced microscope system specially designed for petrographic applications. It has two light sources: a 20W halogen Kohler transmitted light and a 50W EPI reflected halogen illuminator. The trinocular head inclines at 45-degrees and is 360-degree rotatable. The microscope assembly includes a bertrand lens for special polarized light analysis and a built in 1.25x auxiliary objective in the light path, further increasing the power of the microscope. The microscope offers five magnification settings with its included objectives and eyepieces, which are 50X, 125X, 312.5X, 500X, and 787.5X. Each of the four objective mounts offers centering adjustment. The circular stage is rotatable and accurate to 0.1 degrees using the vernier scale. The kit also includes many accessories for analysis and operation, such as a blue light filter for transmitted light, a green light filter for reflected light, a HDMI C-Mount digital microscope camera system, three extra eyepieces with various reticles for counting, centering, or measurement, a mechanical stage attachment, and polarizing compensators for use with the Bertrand lens.
This 1920x1080, 60fps via HDMI, 30 fps via USB2.0 digital camera kit allows for live viewing and recording of your microscope image with ease and extremely high quality!
This is a perfect microscopy system for mineral applications. It is an ideal instrument for those in mineralogy and/or geology areas.
