The XD-series inverted biological/fluorescence microscope is a professional inverted microscopic imaging system launched by Abner for the fields of life science, cell biology and medical research. Adopting a high-performance infinity-corrected optical system and inverted optical path structure design, the system is especially suitable for long-term observation and fluorescence imaging of living samples such as petri dishes, culture flasks and multi-well plates.
On the basis of ensuring high-resolution imaging and system stability, the XD series integrates brightfield and multi-channel epifluorescence imaging capabilities, and can flexibly expand digital imaging and image analysis modules. It is widely used in experimental scenarios such as cell culture, live cell imaging, fluorescent labeling and dynamic process research.
I. Product Features
Inverted optical structure, suitable for cell culture experiments
The objective lens is positioned below the sample, enabling direct observation of petri dishes, culture flasks and multi-well plates and reducing sample interference.
Infinity-corrected optical system
Designed for high image quality and low chromatic aberration, supporting both brightfield and fluorescence imaging to meet research-grade observation requirements.
Multi-channel epifluorescence imaging
Compatible with a variety of fluorescent dyes for cell labeling, protein localization and functional research applications.
Highly stable integrated body
Metal frame structure effectively suppresses vibration and drift, ideal for long-term and live-cell imaging experiments.
Modular and expandable design
Fluorescence modules, cameras, filter sets and software functions can be configured as needed for easy upgrade and maintenance.
