Lumencor SOLA Solid-State White Light Source for Fluorescence Microscopy

Overview

The Lumencor SOLA is a high-performance, solid-state white light source engineered specifically for demanding fluorescence microscopy applications. Unlike traditional arc-lamp-based illumination systems—such as mercury or xenon lamps—the SOLA integrates multiple solid-state emitters (including narrowband LEDs, laser diodes, and Lumencor’s proprietary broadband light pipes) into a single, thermally stabilized optical engine. Its core innovation lies in the patented Lumencor Light Pipe technology, which delivers high-intensity, spectrally smooth output across the 500–600 nm range—effectively bridging the so-called “green gap” where conventional LEDs exhibit low quantum efficiency and poor radiant flux. The system operates on a true white-light principle: spectral composition is not generated via phosphor conversion but through precise spatial and temporal combination of discrete, independently controllable emitters. This architecture enables stable, flicker-free illumination with sub-millisecond switching between channels, making it suitable for time-resolved imaging, multi-color FISH, optogenetics stimulation, and high-content screening workflows requiring strict photometric reproducibility.

Key Features

• Mercury-free design: Eliminates hazardous material handling, disposal compliance burdens, and regulatory reporting under RoHS, WEEE, and REACH directives.
• Thermally managed solid-state architecture: No warm-up or cool-down cycles required; achieves operational stability within seconds at ambient temperature (20–25°C).
• Independent channel control: Up to six discrete spectral bands (configurable per model), each with analog intensity modulation (0–100%) and TTL-triggered on/off capability.
• Lumencor Light Pipe technology: Delivers >100 mW broadband output in the 520–580 nm window with <±3% intensity drift over 8 hours—validated per ISO 9022-18 photometric stability protocols.
• Long service life: Rated for ≥25,000 hours of operation (L70 lifetime metric), translating to ~15 years under typical lab usage (8 hrs/day, 5 days/week).
• Plug-and-play integration: Includes 3 mm liquid light guide (LLG), USB 2.0 interface, and power supply; compatible with standard microscope epi-illumination ports via C-mount or fiber-coupled adapters.

Sample Compatibility & Compliance

The SOLA is designed for use with fixed and live biological specimens across widefield, confocal, TIRF, and light-sheet modalities. It supports fluorophores spanning DAPI, FITC, TRITC, Cy3, Cy5, Alexa Fluor dyes, GFP/RFP variants, and newer far-red/near-IR probes (e.g., Cy7, IRDye 800CW). All optical components comply with ISO 10110 surface quality standards; electrical safety meets IEC 61010-1 Ed.3 requirements for laboratory equipment. The device is CE-marked and conforms to FCC Part 15 Class B emission limits. For regulated environments (GLP/GMP labs), firmware supports audit-trail logging via optional software modules compliant with FDA 21 CFR Part 11 Annex 11 requirements.

Software & Data Management

The SOLA is operated via Lumencor’s proprietary SpectraViewer™ GUI (Windows/macOS), offering intuitive channel selection, intensity ramping, preset recall, and external synchronization (via TTL, USB, or Ethernet). Software logs all illumination events—including timestamped power settings, duration, and trigger sources—for traceable experiment documentation. Export formats include CSV and JSON for integration with LabArchives, Benchling, or custom LIMS platforms. Firmware updates are delivered through secure HTTPS channels with SHA-256 signature verification.

Applications

• Fluorescence in situ hybridization (FISH) with multi-target probe sets requiring simultaneous or sequential excitation.
• Optogenetic actuation using ChR2, C1V1, or ReaChR opsins under precise temporal control.
• High-content analysis (HCA) in automated cell screening platforms where illumination consistency directly impacts Z’-factor reliability.
• Endomicroscopy and microendoscopy illumination where compact size, low heat load, and flexible light delivery are critical.
• Microfluidic chip-based assays requiring uniform, low-phototoxicity illumination over extended acquisition periods.

FAQ

Is the SOLA compatible with Nikon, Olympus, Zeiss, and Leica fluorescence microscopes?
Yes—mechanical and optical interfaces are available for all major OEM platforms via standardized C-mount, SMA905, or liquid light guide couplers.
Does the SOLA require recalibration after installation?
No. Factory calibration is retained across power cycles; optional annual verification services are available through Lumencor-certified labs.
Can output intensity be modulated during image acquisition?
Yes—intensity is continuously adjustable via analog voltage input (0–5 V) or digital commands, supporting real-time exposure matching in synchronized acquisition modes.
What maintenance is required over its operational lifetime?
None beyond periodic inspection of the liquid light guide coupling interface; no consumables, filters, or lamp replacements are necessary.
How does the SOLA handle thermal management during extended operation?
It employs passive conduction cooling combined with intelligent thermal feedback loops that dynamically adjust drive current to maintain junction temperature below 65°C—ensuring spectral stability and longevity.
