The HL-2000 Tungsten Halogen Light Source Series is a family of fiber-coupled VIS-NIR illumination systems designed for spectroscopy, optical sensing, analytical instrumentation, and laboratory measurement applications requiring stable broadband output across the visible and near-infrared spectral regions. Covering wavelengths from approximately 360 nm to 2400 nm, these tungsten halogen light sources provide continuous spectral output suitable for absorbance spectroscopy, transmission measurements, reflectance analysis, optical characterization, and fiber-optic spectroscopy workflows.

The HL-2000 series includes multiple configurations optimized for either long lamp lifetime or enhanced optical power. Long-life models support operating lifetimes up to 10,000 hours for routine laboratory use and OEM integration, while high-power configurations provide increased optical throughput for applications using large-core optical fibers, probe bundles, integrating spheres, and low-signal spectroscopy systems.

These tungsten halogen light sources incorporate integrated cooling fans, fiber-coupled SMA 905 optical interfaces, and optional shutter and attenuator functionality to support stable and repeatable spectroscopic measurements. Select models also support TTL and RS-232 control for automated spectroscopy platforms and computer-controlled optical instrumentation.

Unlike narrowband laser illumination systems, tungsten halogen lamps produce smooth broadband spectral emission throughout the VIS-NIR wavelength range, making them particularly useful for UV-Vis absorbance spectroscopy, transmission spectroscopy, color measurements, reflectance testing, biomedical optics, and general-purpose optical characterization. Their continuous spectral output enables flexible integration with miniature spectrometers, monochromators, optical benches, and fiber-optic spectroscopy systems.

The HL-2000 family also supports optical filtering and beam conditioning through integrated filter holders capable of accommodating round and square optical filters. Combined with adjustable fiber coupling and stable broadband illumination, these systems are well suited for laboratory spectroscopy, industrial optical sensing, environmental analysis, educational spectroscopy platforms, and OEM analytical instrumentation integration.
