EXC-250

EXC-250

The NEW ACCU-SCOPE® EXC-250 Microscope Series is a fully redesigned laboratory and educational microscope built to deliver outstanding optical performance, long-term reliability, and exceptional value. As the successor to our popular 3000-LED biological microscope, the EXC-250 brings enhanced clarity, brighter illumination, and improved ergonomics to today’s clinical laboratories, veterinary practices, physician offices, and higher education programs.

Featuring an advanced Infinity Plan optical system, a best-in-class 20mm field of view, and a new super-bright 5-watt LED, the EXC-250 produces crisp, high-contrast images suitable for routine diagnostics, teaching applications, and demanding life science research.



KEY FEATURES

Brilliant LED Illumination & High-Resolution Optics

Engineered for precision, the EXC-250’s Infinity Plan optical system works in harmony with its newly developed LED illumination to provide flat, high-resolution, high-contrast images across every magnification. The long-lasting 25,000+ hour LED light source maintains a stable color temperature—ideal for brightfield, phase contrast, and challenging 100x oil immersion work.

Perfect for clinical, veterinary, and teaching environments where image quality matters most.

Classroom Friendly. Laboratory Ready.

Designed for seamless setup, this biological microscope arrives ready to use—no complicated assembly needed. Its compact, sturdy footprint and cast alloy aluminum frame ensure durability in busy teaching labs and diagnostic settings.

An integrated, ergonomic carry handle makes moving the EXC-250 from bench to storage quick, safe, and efficient.

Ergonomic Design for All-Day Use

The EXC-250 supports comfortable, strain-free operation for students and professionals alike. Low-positioned coaxial focusing knobs allow hands to rest naturally on the workbench, while newly designed low-profile stage controls make slide navigation precise and effortless.

A variable-intensity illumination wheel and a 30° inclined viewing head with HWF PL10x eyepieces help maintain proper posture during extended observation sessions—ideal for high-volume labs and multi-hour instruction.

Clutter-Free Storage & Easy Handling

With its integrated cord wrap and compact rotating head, the EXC-250 simplifies storage in classrooms, clinics, and lab facilities. The head rotates 180° to reduce shelf depth, and the built-in carry handle ensures safe, stable transport for routine storage or quick lab reconfiguration.

Digital Imaging Ready: Cameras & Monitors

Every EXC-250 comes standard with a trinocular microscope head (50:50 split), making it easy to add digital microscope cameras, including Excelisâ„¢ 4K, HD, USB, and WiFi models. Connect directly to HD monitors or projectors for group instruction, case reviews, or live demonstrations.

Pair with our compact HD imaging monitors for a computer-free digital microscopy solution—perfect for classrooms and space-conscious laboratory environments.

Get Charged Up!

A built-in 5V/1A USB charging port keeps mobile devices powered—ideal when using a WiFi-enabled camera to live-stream or capture microscope images directly to a phone or tablet.

Phase Contrast, Polarization & Darkfield Options

Expand your EXC-250 to meet evolving laboratory requirements. The microscope supports slider phase contrast, polarization with gout analyzer, and darkfield techniques—making it a versatile choice for routine diagnostics, veterinary sample analysis, and life science instruction.
