AvaSpec-ULS4096CL-EVO – High-Resolution UV/VIS/NIR Spectrometer
High-resolution spectral measurement with 4,096 pixels
The AvaSpec-ULS4096CL-EVO is a high-resolution fiber-optic spectrometer for demanding spectral measurements in the UV, visible and near-infrared range from 200 to 1,100 nm.
With its 4,096-pixel CMOS detector, the system is specifically designed for applications requiring particularly detailed spectral resolution. Depending on the optical configuration, resolutions of up to 0.05 nm are possible.
At BF Engineering, we use the spectrometer in particular for the detailed characterization and development of advanced light sources. The high number of detector pixels enables narrow spectral structures and emission lines to be analyzed with high precision.

Spectral analysis with 4,096 pixels
The AvaSpec-ULS4096CL-EVO combines a 4,096-pixel CMOS detector with a high-performance optical system and fast processing electronics.
The key advantage is its ability to capture spectral structures with particularly high detail and resolution.
This is especially relevant for light sources whose spectra consist of numerous narrow emission lines or complex spectral structures.
The ULS4096CL-EVO is therefore particularly suitable for high-resolution spectral measurements, plasma applications and emission spectroscopy.
For the development of modern light sources, the system provides a powerful basis for detailed spectral investigations.

High-resolution spectral measurement for advanced light sources
The AvaSpec-ULS4096CL-EVO is particularly suitable for applications requiring high spectral resolution and precise detection of individual spectral structures.
Typical applications include:
- Plasma light sources
- Plasma diagnostics
- Emission spectroscopy
- Solar simulation
- UV light sources
- LED characterization
- HMI light sources
- Spectral irradiance measurements
- Research & development
- Quality assurance
- Development of new light source technologies
At BF Engineering, the focus is particularly on the detailed spectral analysis of HMI, LED, UV and plasma light sources.
4,096 pixels for maximum spectral detail
The CMOS detector of the ULS4096CL-EVO features 4,096 individual pixels.
In combination with suitable gratings and entrance slits, this enables a spectral resolution of up to 0.05 nm.
This allows closely spaced spectral structures to be differentiated and individual emission lines to be analyzed in detail.
This is particularly relevant in the development of plasma light sources, as their spectra can contain numerous different emission lines and spectral structures.
The high spectral resolution makes it possible to precisely analyze changes in the spectrum under different operating conditions.
Detailed analysis of artificial solar spectra
In the development of solar simulation systems, the ULS4096CL-EVO also enables detailed analysis of the spectral irradiance distribution.
The measurement range from 200 to 1,100 nm covers key regions of UV, visible light and near-infrared radiation.
This allows different light source technologies to be spectrally characterized and compared.
The measurement data can be used for tasks including:
- Analysis of spectral irradiance
- Comparison of different light sources
- Investigation of individual emission ranges
- Optimization of spectral composition
- Development of new light sources
- Validation of solar simulation systems
High-resolution spectroscopy therefore complements conventional total irradiance measurements by providing a significantly more detailed analysis of the actual spectral characteristics of a light source.
High-end spectral measurement in our own laboratory
At BF Engineering, we use modern spectral measurement technology for the development and validation of high-performance lighting and irradiation systems.
The AvaSpec-ULS4096CL-EVO expands our measurement capabilities, particularly in the field of high-resolution spectral analysis.
We analyze various light source technologies, including:
HMI · LED · UV · Plasma
Especially in the development of modern plasma light sources, the high spectral resolution enables detailed analysis of individual emission ranges and spectral changes under different operating conditions.
The measurement data obtained is incorporated directly into the research, product development, optimization and validation of new light source technologies.
This provides us with in-house measurement capabilities from the initial prototype through to the final characterization of a lighting system.
