Leica DM500 Upright Biological Microscope

Overview

The Leica DM500 is an upright biological microscope engineered for reliability, ease of use, and pedagogical clarity in academic teaching laboratories, quality control environments, and clinical diagnostic settings. Built on the same optical architecture as Leica’s research-grade upright platforms, the DM500 delivers consistent Köhler illumination, high-contrast brightfield imaging, and precise mechanical stability—without requiring advanced user calibration. Its optical train features achromatic objectives (4×, 10×, 40×, and a proprietary 100× dry objective), a pre-aligned Abbe condenser (NA 1.25), and a fixed-tube-length optical path optimized for reproducible magnification and minimal chromatic aberration. The instrument operates on a rigid, low-vibration chassis with a self-supporting SAFESTAGE™ mechanical stage, eliminating reliance on external support arms and reducing mechanical drift during extended observation sessions.

Key Features

• True “Plug-and-Play” Operation: Factory pre-centering and pre-focusing of the condenser eliminate manual alignment—users achieve optimal illumination immediately after power-on.
• Ergonomic & Infection-Control Design: AgTreat™ antimicrobial coating applied to all high-touch surfaces (focus knobs, stage controls, eyepiece tubes) inhibits bacterial colonization per ISO 22196:2011 testing protocols, supporting hygiene-critical environments such as undergraduate labs and clinical training suites.
• Dry 100× Objective: Eliminates immersion oil handling, cleaning cycles, and associated risks of lens contamination or refractive index mismatch—ideal for rapid student-led microscopy workflows.
• Integrated LED Illumination (EZLite™): Cold-white LED light source (CCT ~5,700 K) provides uniform, flicker-free illumination across the full field of view; rated for 25,000 hours at nominal brightness, reducing maintenance intervals and total cost of ownership.
• Modular Observation System: EZTube™ binocular head integrates eyepieces with factory-set diopter correction, preventing misconfiguration; optional ICC50-series digital cameras connect directly via rear USB 5 V / 1.5 A port—no external power adapters or cable clutter required.
• Transport & Storage Safety: EZStore™ vertical grip and front-panel recessed channel enable two-handed, stable lifting; integrated cable management prevents strain on connectors during storage or relocation.

Sample Compatibility & Compliance

The DM500 accommodates standard 1″ × 3″ (25 × 75 mm) glass slides and 0.17 mm coverslips. Its mechanical stage supports both manual and motorized slide advancement (with optional upgrade). The system complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-1 (immunity), and its construction adheres to RoHS Directive 2011/65/EU. While not certified for GMP production environments, the DM500 meets essential requirements for GLP-compliant documentation when paired with Leica Application Suite (LAS) X software and ICC50 camera systems—including audit-trail-capable image metadata logging (time stamp, objective ID, exposure settings) aligned with FDA 21 CFR Part 11 principles.

Software & Data Management

The DM500 is fully compatible with Leica Application Suite (LAS) X v3.7+ for image acquisition, annotation, measurement (length, area, particle count), and report generation. When used with ICC50 HD cameras, LAS X enables real-time streaming, time-lapse capture, and multi-channel overlay (e.g., phase contrast + fluorescence simulation). All captured images embed EXIF-style metadata—objective magnification, condenser position, LED intensity level, and user-defined tags—ensuring traceability in educational assessment or QC documentation. Optional LAS X Education Edition includes guided workflows for common undergraduate experiments (e.g., mitosis staging, blood smear analysis, plant cell structure identification).

Applications

• Undergraduate life science instruction: histology, microbiology, botany, and physiology labs requiring rapid setup and consistent image quality.
• Industrial quality assurance: routine inspection of cultured cells, tissue sections, or particulate contaminants in pharmaceutical raw materials.
• Clinical training: peripheral blood smear evaluation, urinalysis sediment screening, and basic parasitology under brightfield and phase contrast modes.
• Veterinary diagnostics: rapid examination of skin scrapings, ear swabs, and fecal flotation preparations.
• Environmental education: pond water microfauna observation, algal identification, and soil microorganism surveys.

FAQ

Does the DM500 support phase contrast imaging?
Yes—the Abbe condenser includes dedicated slots for phase contrast sliders, including Leica’s 4-position slider that combines brightfield and multiple phase contrast settings (Ph1, Ph2, Ph3) in a single unit.
Is the 100× objective truly oil-free?
Yes—the proprietary 100× dry objective achieves NA 0.85 without immersion oil, delivering resolution comparable to conventional 100× oil objectives while eliminating cleaning steps and refractive index variability.
Can the DM500 be used with third-party digital cameras?
It supports C-mount and CS-mount cameras via optional adapter tubes; however, only Leica ICC50-series cameras receive native USB power from the rear port—third-party devices require separate power supplies.
What is the warranty coverage for the DM500?
Leica offers a standard 2-year limited warranty covering parts and labor for defects in materials and workmanship, extendable to 3 years with registration and service plan enrollment.
Is the AgTreat™ coating effective against viruses?
AgTreat™ is validated per ISO 22196 against Gram-positive and Gram-negative bacteria (e.g., Staphylococcus aureus, Escherichia coli); antiviral efficacy is not claimed or tested per current regulatory frameworks.
