Oxxius FlexxRay lasers – compact CW and modulated lasers (375–1064 nm, diode and DPSS)

FlexxRay is a series of compact CW and modulated lasers from Oxxius, covering more than 30 wavelengths in the 375–1064 nm range (UV–VIS–NIR), with power up to 1000 mW. It combines two technologies — diode lasers (LBX) and DPSS lasers (LCX/LPX) with frequency conversion — delivering a TEM₀₀ beam of excellent quality, low optical noise and high stability. It is a versatile light source for fluorescence microscopy, flow cytometry, spectroscopy and OEM integration.

FlexxRay lasers are designed as ready-to-integrate laser sources with industrial reliability. Integrated control electronics, a stable mechanical design and a standard 100×40 mm footprint make them suitable both for laboratory use (plug-and-play version) and for embedding in equipment (OEM version). Diode models (LBX) provide fast direct modulation and a wide choice of wavelengths, while DPSS models (LCX/LPX) offer a narrow spectral linewidth for wavelengths not directly available from a diode — 532, 553, 561 and 607 nm.

The FlexxRay series combines two complementary technologies. The choice depends on the wavelength and the required spectral purity:

• TEM₀₀ beam (Gaussian) — smallest focal spot, highest brightness, best fiber coupling
• Low optical noise — as low as ≤0.2 % rms (10 Hz–20 MHz)
• Power stability ±0.5 % over 8 h
• Fast modulation — digital up to 150 MHz (diode models)
• Integrated control electronics, USB and RS-232 interfaces
• Compact, standard footprint 100×40 mm
• Full compatibility with MixxWave combiners — combining multiple lines in a single fiber

The full range covers more than 30 wavelengths. DPSS models 532, 553 and 561 nm are available in fixed and adjustable power versions. Full data in the brochure below.

• Fluorescence and confocal microscopy — standard lines 405, 445, 488, 515, 532, 561, 638 nm
• Flow cytometry — stable, low-noise excitation
• Raman spectroscopy — 532 nm (DPSS) and 785 nm
• Quantitative imaging and super-resolution techniques
• NIR applications — 785–1064 nm
• OEM integration in analytical and medical instrumentation

Each FlexxRay laser can be configured for a specific application:

• Fiber coupling — single-mode (SM), polarization-maintaining (PM) or multimode (MM), FC/APC, FC/PC, SMA connectors
• Thermal management — HTSK heat sinks (required above 300 mW)
• Electromechanical shutter as additional safety
• Band-pass (clean-up) filter — improved spectral purity
• Laboratory version (PP) — complete plug-and-play kit, compliant with safety standards
• OEM version — laser head only for system integration

We supply Oxxius FlexxRay lasers as individually configured solutions — wavelength, power, fiber coupling type, modulation and version (laboratory or OEM) are selected for the specific application.
