1. Product Overview
The EX-33 series is ABN's laboratory-grade upright microscope, including biological, fluorescence, digital and other models. It adopts an infinite achromatic optical system and plan achromatic objectives. Equipped with 2X/4X/10X/20X/40X/60X/100X objectives as standard, paired with PL10X eyepieces, it achieves a total magnification ranging from 20X to 1000X. The front-mounted LCD screen displays magnification, light intensity, color temperature and ECO status in real time. Objective encoding and light intensity memory enable quick switching. The 360° rotatable observation tube supports multi-person operation. The double-layer ceramic linear stage can hold two slides simultaneously and is compatible with fluorescence modules and microscope cameras. It is widely applied in clinical diagnosis, cell research, material analysis and teaching demonstration. The observation tube of the EX-33 series features a hinge assembly for 360° rotation, with adjustable interpupillary distance and eye point height, delivering a more flexible and comfortable operating experience for operators of different heights. As a new member of our laboratory biological microscope family, the EX-33 inherits ABN's consistently excellent optical performance, incorporates an intelligent management mode, and adopts a brand-new design style for an all-round upgraded user experience.
