Horiba JY FM-4 Fluorescence Spectrometer Compatible 150 W Ozone-Free Xenon Lamp

Overview

The Horiba JY FM-4 Fluorescence Spectrometer Compatible 150 W Ozone-Free Xenon Lamp is a precision-engineered replacement light source designed exclusively for integration with the Horiba Scientific FluoroMax-4 fluorescence spectrometer platform. This lamp utilizes a high-stability, short-arc xenon discharge architecture to deliver intense, continuous spectral output across the deep UV (190 nm) to near-infrared (1,100 nm) range — critical for high-sensitivity steady-state and time-resolved fluorescence measurements. Unlike mercury or deuterium lamps, the xenon lamp provides broad, smooth spectral irradiance without discrete emission lines, enabling accurate excitation scanning and reliable quantification across diverse fluorophores. Its ozone-free quartz envelope eliminates the need for external ventilation or ozone scrubbing systems, supporting safe operation in standard laboratory environments while maintaining optical path integrity and minimizing background interference in low-light detection.

Key Features

• 150 W DC-stabilized xenon arc lamp with optimized electrode geometry for extended operational lifetime and reduced thermal drift
• Ozone-free fused silica envelope with high UV transmission (>85% at 200 nm) and minimal solarization under prolonged use
• Pre-aligned lamp housing compatible with Horiba JY FluoroMax-4’s internal illumination optical train — no recalibration required upon installation
• Factory-tested for spectral radiance uniformity and arc stability (±0.5% intensity variation over 30 min at rated power)
• Integrated thermal management design compliant with IEC 61000-3-2 harmonic current emission standards
• RoHS-compliant construction with traceable manufacturing batch documentation per ISO 9001:2015 certified production line in Japan

Sample Compatibility & Compliance

This lamp supports all standard FluoroMax-4 measurement configurations, including front-face, right-angle, and fiber-coupled detection geometries. It is validated for use with aqueous, organic, and solid-state samples — from dilute protein solutions (e.g., tryptophan quantum yield assays) to quantum dot suspensions and thin-film phosphors. The lamp meets essential regulatory requirements for analytical instrumentation in GLP and GMP environments: its electrical safety conforms to IEC 61010-1; UV emission profile complies with EN 62471 (Photobiological Safety of Lamps); and operational traceability aligns with FDA 21 CFR Part 11 data integrity expectations when paired with Horiba’s DataStation software. No modification to the spectrometer’s firmware or hardware is required for full functional compatibility.

Software & Data Management

When installed in a FluoroMax-4 system running Horiba’s DataStation v4.x or later, the lamp is automatically recognized via the instrument’s internal lamp identification protocol. Software-controlled lamp ignition, warm-up stabilization (typically 15–20 min), and power ramping are fully integrated into acquisition workflows. All lamp usage metrics — including total operating hours, ignition cycles, and average current draw — are logged in the instrument’s audit trail and exported as CSV-compatible metadata alongside spectral datasets. These logs support preventive maintenance scheduling and satisfy laboratory quality system requirements for instrument qualification (IQ/OQ/PQ) documentation.

Applications

• Quantitative fluorescence spectroscopy of biomolecules (proteins, nucleic acids, coenzymes) requiring excitation below 220 nm
• Time-resolved fluorescence decay analysis using TCSPC modules, where stable, pulse-capable excitation is essential
• Fluorescence anisotropy studies demanding high polarization purity and minimal spectral shift during intensity modulation
• LED and phosphor material characterization under broadband excitation mimicking solar spectrum conditions
• Environmental analysis of polycyclic aromatic hydrocarbons (PAHs) in water matrices using synchronous scanning techniques
• Pharmaceutical formulation stability testing per USP Analytical Instrument Qualification guidelines

FAQ

Is this lamp an original Horiba JY OEM part?
No — it is a Ushio-manufactured 150 W xenon lamp engineered to meet Horiba JY FluoroMax-4 mechanical, electrical, and photometric specifications. It is not branded by Horiba but is functionally identical to the original lamp assembly supplied with the instrument.
What is the expected operational lifetime under standard usage conditions?
Rated for ≥1,000 hours at nominal 150 W DC power with proper cooling and stable line voltage (±2%). Lifetime may vary depending on warm-up/cool-down cycling frequency and ambient temperature.
Does installation require professional service or recalibration?
No — the lamp is designed for user-level replacement following Horiba’s documented procedure (Service Manual Rev. 4.2, Section 5.3). Optical alignment remains unchanged; no post-installation wavelength or intensity recalibration is necessary.
Can this lamp be used with other Horiba models such as the FluoroMax-3 or NanoLog?
It is mechanically and electrically incompatible with earlier FluoroMax generations due to differences in lamp socket interface, power supply protocol, and cooling duct geometry. Use only with FluoroMax-4 systems.
How is lamp performance verified prior to shipment?
Each unit undergoes spectral radiance profiling (200–800 nm), arc centering verification, and DC current stability testing at Ushio’s Yokohama facility. A certificate of conformance with test data is included with every shipment.
