Laite CX33-UVBGY-E Four-Channel Motorized Upright Fluorescence Module for Olympus CX33 Microscope

Overview

The Laite CX33-UVBGY-E is a purpose-engineered, four-channel motorized fluorescence illumination module designed exclusively for integration with the Olympus CX33 upright microscope platform. It operates on solid-state LED excitation principles—replacing traditional mercury or xenon arc lamps—with discrete, narrow-band LED sources centered at ultraviolet (UV), blue (B), green (G), and yellow (Y) wavelengths. This architecture enables precise spectral matching to common fluorophores while eliminating warm-up delays, ozone generation, and rapid photobleaching associated with broadband sources. The module adheres to Köhler illumination geometry and incorporates optimized excitation/emission dichroic beam splitting and barrier filtering within each integrated filter cube. Its optical path maintains full compatibility with standard 10×–100× objective lenses used on the CX33, preserving native resolution and field uniformity across all channels.

Key Features

• Motorized four-position filter turret with programmable positioning repeatability ±0.1°, enabling sub-second channel switching without manual intervention.
• Modular LED light engine with independently controllable 3W, 5W, or 10W output per channel—adjustable via front-panel encoder or external TTL/USB interface for intensity ramping and pulse modulation.
• Integrated thermal management system featuring copper heat sinks, low-noise axial fans, and real-time temperature monitoring—ensuring stable LED output over continuous operation (>8 hours at rated power).
• Pre-aligned, factory-calibrated fluorescence filter cubes (DAPI, GFP, FITC, Cy3, TRITC, mCherry, Cy5) mounted in precision-machined aluminum housings; all cubes comply with ISO 10110-7 surface quality standards (scratch-dig 20–10).
• Optomechanical design fully compliant with Olympus CX33 trinocular port specifications (23.2 mm thread, 160 mm mechanical tube length), requiring no adapter or optical correction.
• EMC-compliant power supply (IEC 61326-1 Class A) and reinforced insulation for laboratory-grade electrical safety (IEC 61010-1).

Sample Compatibility & Compliance

The CX33-UVBGY-E supports fixed and live biological specimens—including cultured cells, tissue sections, whole-mount embryos, and microorganisms—mounted on standard 1 mm-thick glass slides or #1.5 coverslips. It is compatible with aqueous, glycerol-based, and silicone oil immersion objectives up to 100× magnification. As a research-use-only (RUO) instrument accessory, it is not intended for clinical diagnosis or therapeutic use and carries no regulatory clearance under FDA 21 CFR Part 809, EU IVDR, or ISO 13485. However, its hardware architecture and firmware logging capabilities support GLP/GMP-aligned documentation workflows when paired with validated acquisition software. All optical components meet RoHS 2011/65/EU and REACH SVHC screening requirements.

Software & Data Management

The module interfaces natively with third-party imaging platforms including NIS-Elements (Nikon), ZEN Blue (Zeiss), and open-source tools such as Micro-Manager and Fiji/ImageJ via USB HID or RS-232 protocols. Motorized filter position and LED intensity settings are timestamped and embeddable into TIFF metadata (using ImageDescription and UserComment tags per TIFF 6.0 specification). Optional SDK provides C++ and Python APIs for synchronization with stage controllers, shutters, and camera exposure triggers—enabling automated multi-channel z-stack acquisition, time-lapse series, and spectral unmixing workflows. Audit trail functionality records user-initiated configuration changes with UTC timestamps and operator ID fields, satisfying basic ALCOA+ data integrity expectations for non-GxP research environments.

Applications

This module serves core applications in academic and industrial life science laboratories, including but not limited to: immunofluorescence localization of subcellular structures (e.g., actin, tubulin, nuclear lamins); co-localization analysis of protein–protein interactions using dual-labeling strategies; live-cell calcium imaging with Fluo-4 or Fura-2 dyes; developmental biology studies involving fluorescent reporter transgenic lines (e.g., Tg(fli1a:EGFP)); and routine QC of antibody labeling efficiency in histopathology workflows. Its UV channel supports DAPI and Hoechst staining for nuclear counterstaining, while the extended red sensitivity (Cy5/mCherry) facilitates detection of far-red probes in multiplexed assays—without cross-talk from adjacent excitation bands due to steep LED spectral roll-off (<5% out-of-band irradiance beyond ±20 nm FWHM).

FAQ

Is the CX33-UVBGY-E compatible with Olympus CX33 microscopes equipped with halogen transmitted-light illumination only?
Yes—the module mounts directly to the vertical fluorescence port and requires no modification to the base microscope’s transmitted-light path.
Can I retrofit this module onto an older CX31 or BX41 system?
No—mechanical and optical interfaces are specific to the CX33’s trinocular head design and flange focal distance; cross-platform installation is not supported.
Does the module include a camera adapter or imaging software?
No—it is an illumination and filter-switching subsystem only; cameras, acquisition software, and mounting adapters must be sourced separately.
What is the expected LED lifetime under continuous operation at maximum output?
Rated minimum L70 lifetime exceeds 25,000 hours for all channels when operated within specified thermal limits (case temperature <45°C).
Are custom filter sets available for specialized fluorophores such as Alexa Fluor 647 or CF dyes?
Yes—custom cubes can be ordered as OEM configurations; lead time and MOQ apply.
