Description

Super Broadband Light Sources for Advanced Optical Testing and Imaging

The Super Broadband Light Sources from Yogel are precision-engineered benchtop instruments designed for applications that demand an ultra-wide spectral range, high power, and exceptional stability. Covering up to 450–2400 nm at a 20 dB range, these sources provide a continuous and flat spectrum that spans the visible, NIR, and extended NIR regions. This makes them highly suitable for modern spectroscopy, optical characterization, and imaging tasks where a single, versatile source can replace multiple narrowband lamps or lasers.

Leveraging advanced supercontinuum generation and fiber-based technology, these broadband sources deliver average output powers of 100 mW, 200 mW, or 400 mW, depending on the selected configuration. The flatness and uniformity of the spectrum help minimize calibration complexity and improve signal-to-noise ratio in measurement systems. Compared with conventional halogen lamps or LED-based systems, these sources offer significantly broader coverage and higher spectral brightness, enabling more accurate measurements across a much larger wavelength window.

A key advantage of these Super Broadband Light Sources is their outstanding power stability. Short-term stability over 15 minutes is specified at ≤±0.02 dB (approximately ≤±0.5%), and long-term stability over 8 hours is ≤±0.05 dB (approximately ≤±1.2%). This level of performance is particularly important in precision spectral analysis, where even small fluctuations can degrade measurement repeatability, shift baselines, and introduce errors. Stable output also reduces the need for frequent reference measurements and recalibration, improving throughput in laboratory and production environments.

The output is delivered through a single-mode Hi-1060 fiber pigtail with random polarization, terminated with an FC/APC connector. This configuration is compatible with standard collimators and fiber-based optical setups found in spectroscopy, OCT, interferometry, and imaging systems. Random polarization helps avoid polarization-related artifacts in many test configurations, while single-mode delivery ensures good beam quality and spatial coherence suitable for precise coupling into instruments or fiber networks.

The platform is designed with user-friendly control and easy integration into automated test setups. A built-in touchscreen interface allows direct local control of operating parameters, while an RS232 serial interface (DB9 female connector) supports remote operation and system integration. The universal 100–240 VAC power supply and less than 150 W power consumption make it suitable for laboratories, OEM racks, and industrial workstations worldwide. With an operating temperature range of -5 to +35 °C and humidity tolerance from 0 to 70%, these units are engineered for reliable performance under typical lab and production conditions.

Typical applications for these ultra-broadband sources include spectral analysis, medical and biomedical imaging, optical inspection, material characterization, and development of photonic components. In spectral analysis, the extended 450–2400 nm or 600–2400 nm range enables simultaneous investigation of visible absorption features, NIR overtones, and deeper NIR-II and NIR-III bands often exploited in chemical sensing and process monitoring. In medical imaging and life sciences, access to NIR-II wavelengths supports higher-contrast, deeper-tissue imaging protocols. For optical inspection and component testing, the wideband output simplifies characterization of filters, waveguides, detectors, and other photonic devices over a very broad spectral window.

Housed in a compact benchtop (B3) chassis with dimensions of 376 mm (W) × 340 mm (D) × 112 mm (H), the Super Broadband Light Sources fit easily into crowded optical tables and test benches. Model configurations cover ultra-broadband ranges such as NIR-II (600–2400 nm) and NIR-III (450–2400 nm), allowing users to select the optimal wavelength coverage and power level for their specific application. This combination of broad spectral coverage, high and stable output power, and flexible control makes Yogel’s Super Broadband Light Sources a robust choice for researchers, system integrators, and manufacturers looking to upgrade or expand their optical testing and imaging capabilities.

Frequently Asked Questions

What is the SC-LS ultra-broadband supercontinuum light source and what wavelength range does it cover?
The SC-LS is a benchtop ultra-broadband supercontinuum light source designed for applications that require a very wide and continuous spectral output. According to the datasheet, it offers two main wavelength configurations: NIR-II with a 600–2400 nm range and NIR-III with a 450–2400 nm range (specified at a 20 dB bandwidth). This broad coverage makes it suitable for visible to shortwave infrared (SWIR) applications such as spectroscopy, imaging, and optical characterization.
What are the typical applications of this super broadband light source?
This ultra-broadband light source is used where a flat, high-power spectrum over a wide wavelength range is required. Typical applications include: (1) spectral analysis and optical spectroscopy in the VIS–NIR–SWIR bands, (2) medical and biomedical imaging (e.g., tissue imaging and optical diagnostics in NIR and SWIR windows), (3) optical inspection and quality control in manufacturing, semiconductors, and materials research, and (4) characterization of optical components, fibers, filters, and detectors across 450–2400 nm.
What output power levels and stability can I expect from the SC-LS broadband light source?
The SC-LS provides average optical output powers of 100 mW, 200 mW, or 400 mW, depending on the selected model. It is designed for high output stability: power stability over 15 minutes is specified as ≤ ±0.02 dB (approximately ≤ ±0.5%), and over 8 hours as ≤ ±0.05 dB (approximately ≤ ±1.2%). This performance is comparable to other high-end supercontinuum and broadband sources on the market used in demanding metrology and imaging applications.
What fiber output, connector type, and polarization state does the light source use?
The SC-LS uses a single-mode fiber pigtail based on Hi-1060 fiber, which is commonly used for supercontinuum and broadband NIR applications. The standard output connector is FC/APC, which is widely compatible with commercial collimators and fiber-optic accessories and helps reduce back reflections. The polarization state is random, which is typical for many supercontinuum sources; users requiring a defined polarization state would typically add external polarization optics at the output.
How do I control and integrate this broadband light source into my setup or automated system?
The SC-LS offers both local and remote control. Locally, it features a touchscreen interface for convenient operation on the benchtop. For system integration and automation, it provides RS232 serial communication via a DB9 female interface. This allows you to control output parameters and monitor status from a PC, test bench controller, or lab automation system. The universal AC input of 100–240 VAC and power consumption under 150 W facilitate integration into standard laboratory environments and test racks.
What are the mechanical dimensions and environmental operating conditions of the SC-LS light source?
The SC-LS is supplied in a benchtop package (type B3) with dimensions of approximately 376 mm (W) × 340 mm (D) × 112 mm (H), which is comparable in size to many laboratory supercontinuum units. It is specified to operate over an ambient temperature range of −5 to +35 °C and a relative humidity range of 0–70% (non-condensing). These conditions cover typical research laboratories, production test floors, and many field or industrial setups where environmental control is moderate.
How do I select the right SC-LS model for my application (NIR-II vs NIR-III and power options)?
Selection primarily depends on your required spectral range and power level. If your application only needs near-infrared to SWIR (600–2400 nm) coverage, the NIR-II configuration is sufficient and can be advantageous where visible light is not needed. If you require visible wavelengths for spectroscopy, microscopy, or white-light imaging, the NIR-III version with a 450–2400 nm range is more appropriate. Then choose among 100 mW, 200 mW, or 400 mW average output power based on your detector sensitivity, required signal-to-noise ratio, and any power limitations of your samples or optics. All versions share the same benchtop form factor, Hi-1060 single-mode output, and control interfaces.
