Nikon ECLIPSE Ni-L Motorized Research-Grade Upright Microscope

Overview

The Nikon ECLIPSE Ni-L is a high-performance, motorized research-grade upright microscope engineered for demanding life science applications—including live-cell imaging, electrophysiology, tissue section analysis, and multimodal fluorescence microscopy. Built upon Nikon’s proven CFI60 and CFI75 infinity-corrected optical platforms, the Ni-L delivers exceptional chromatic correction, high transmission efficiency, and scalable modularity across brightfield, phase contrast, DIC, darkfield, and epi-fluorescence modalities. Its dual-motorized focusing architecture—supporting independent vertical movement of either the stage or nosepiece—enables precise Z-stack acquisition while preserving sample integrity during long-term time-lapse experiments. The integrated linear encoder (0.025 µm resolution) ensures repeatable, traceable focus positioning, critical for quantitative image analysis and automated assay workflows in regulated environments.

Key Features

• Motorized dual-Z focusing system: Selectable vertical actuation via motorized stage (±13 mm travel) or motorized nosepiece (±13 mm travel), with programmable return-to-reference and auto-refocus functions.
• High-stability CFI60/CFI75 optical architecture: Optimized for low-autofluorescence, high-signal fidelity, and compatibility with high-NA objectives (up to 100× oil immersion) and advanced contrast techniques including DIC and polarization.
• Intelligent illumination management: Dual-source capability—12V/100W halogen lamp with NCB11, ND8, ND32, and diffuser filters—or high-CRI LED (50,000 h rated lifetime) with built-in neutral density control and intensity preset memory.
• Modular port architecture: Supports simultaneous multi-camera output via tilting quad-port tube (NI-TT2-E), motorized zoom port (NI-RPZ-E, 0.6×–2.0×), and standardized C-mount/F-mount DSC interfaces with calibrated magnification options (0.55×, 0.7×, 1.0×, 2.5×).
• Precision motion control: NI-S-E motorized XY stage (78 × 54 mm travel, 0.1 µm step resolution) and NI-N7-E 7-position motorized nosepiece with encoded position feedback for reproducible objective switching and protocol-driven imaging sequences.
• Ergonomic and regulatory-ready design: Fully compliant with ISO 13485-aligned manufacturing standards; supports audit trail generation, user access control, and electronic signature integration when paired with Nikon NIS-Elements AR or other 21 CFR Part 11–validated software suites.

Sample Compatibility & Compliance

The ECLIPSE Ni-L accommodates a broad range of specimen formats—from standard glass slides and Petri dishes (with optional NI-SH-D dish holder) to thick-sectioned tissues, organotypic slices, and live-animal preparations on FN1-compatible stages. Its extended working distance condensers (e.g., NI-CUD-E, NA 0.88) and LWD objectives support imaging through culture vessels and chambered coverslips without optical compromise. The system meets mechanical and electrical safety requirements per IEC 61010-1 and is designed for use in ISO Class 5–7 cleanroom environments. All optical components are certified free of hazardous substances per RoHS Directive 2011/65/EU. For pharmaceutical and clinical research labs, the Ni-L’s deterministic hardware control layer enables full alignment with GLP documentation standards and GMP validation protocols—including IQ/OQ/PQ execution and calibration traceability to NIST-traceable references.

Software & Data Management

The Ni-L operates natively with Nikon NIS-Elements platform (v5.0+), supporting fully automated acquisition, multi-dimensional stitching, spectral unmixing, and AI-assisted segmentation. Hardware-level synchronization ensures sub-millisecond timing accuracy between stage motion, filter wheel actuation, shutter control, and camera exposure—essential for FRET, FRAP, and calcium imaging. When configured with NI-CTLB control box and compatible peripherals, the system logs all hardware state changes (objective position, Z-height, illumination intensity, filter selection) into an encrypted, tamper-evident audit trail. This functionality satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures in regulated biopharmaceutical development and QC testing.

Applications

• Long-term live-cell imaging under controlled environmental chambers (CO₂, temperature, humidity)
• High-content screening (HCS) with automated multi-well plate navigation and focus mapping
• Neuroscience applications: Patch-clamp combined with epifluorescence or IR-DIC visualization
• Developmental biology: Time-lapse imaging of zebrafish, C. elegans, and mouse embryo explants
• Pathology and histopathology: Digital slide scanning preparation with consistent focus stacking and color fidelity
• Materials science correlative workflows: Overlay of optical morphology with SEM or AFM topography data

FAQ

Is the ECLIPSE Ni-L compatible with third-party cameras and controllers?
Yes—the Ni-L provides TTL, RS-232, and USB 2.0 interfaces for seamless integration with industry-standard sCMOS, EMCCD, and scientific CMOS cameras, as well as external environmental control systems.
Can the system be validated for use in GxP-regulated laboratories?
Absolutely. With appropriate configuration (e.g., NI-CTLB control box, NIS-Elements AR with audit trail module), the Ni-L supports full IQ/OQ/PQ documentation, electronic signature enforcement, and 21 CFR Part 11 compliance verification.
What is the maximum usable field of view (FOV) at the camera port?
When using the CFI UW10X eyepiece (25 mm FOV) and NI-RPZ-E motorized zoom port set to 0.6×, the effective camera FOV reaches 41.7 mm diagonal—enabling wide-field tile scanning without sacrificing resolution.
Does Nikon provide application-specific training and service support for the Ni-L platform?
Yes—Nikon Instruments offers factory-certified installation, application engineering support, and annual preventive maintenance contracts with SLA-backed response times for global customers.
