Prepared for use in regulated laboratory conditions, the Transmitted Light Microscope OBL Series OBL 137 Trinocular falls under the category of light field microscopes. This model boasts flexible and versatile functionality, particularly suited for laboratories dealing with translucent, low-contrast specimens such as living mammalian cells, bacteria, and tissues. Its infinity corrected optics guarantee superior image quality, while the 4-slot lens revolver comes equipped with four high-quality, infinitely corrected E-PLAN lenses for enhanced edge definition. Additionally, the 1.25 Abbe condenser with aperture cover facilitates easy Köhler illumination, ensuring optimal specimen illumination without any negative flare effects. The mechanical cross table allows for swift specimen working and positioning, featuring a coaxial coarse and fine focus drive for adjusting height and
