Accu-Scope EXC-250 Microscope - KOH Microscope

The EXC-250 Trinocular Microscope from Accu-Scope is a modern laboratory workhorse engineered for reliability, optical clarity, and everyday ease of use. Designed as the successor to the 3000-LED series, the EXC-250 delivers upgraded optics, improved ergonomics, and full digital-imaging readiness—making it an excellent choice for clinical labs, education, and research environments. Exceptional Optical Performance The advanced Infinity Plan achromat optical system paired with a super-bright 5-watt LED illuminator produces crisp, flat, high-contrast images across the full field of view. With a best-in-class 20 mm field, the EXC-250 excels in brightfield, phase contrast, and 100x oil immersion applications. Built for the Lab and Classroom A durable cast-alloy frame, compact footprint, and intuitive controls make this microscope ideal for high-usage environments. Thoughtful conveniences like an integrated carry handle, cord wrap, and built-in USB power port for charging mobile devices add day-to-day practicality. Ergonomics That Reduce Fatigue User comfort is front and center with a 30° inclined trinocular viewing head, low-positioned coaxial focus controls, and low-profile stage controls—all designed to minimize strain during extended sessions. Digital Imaging Ready The standard trinocular head with a 50:50 light split supports Excelis™ cameras and USB, HD, or Wi-Fi imaging solutions, making the EXC-250 ideal for documentation, instruction, and collaborative viewing. Expandable & Versatile The EXC-250 supports phase contrast, darkfield, and polarization upgrades without compromising image quality, allowing the system to grow with your application needs.
