Are you looking for a versatile and precise way to measure UV LED output? The EIT 2.0 LEDCure® Profiler and LEDCure® Profiler Four Band radiometers offer two distinct yet complementary approaches to UV LED measurement, catering to both production line simplicity and in-depth laboratory analysis. This blog post explores the unique features and benefits of each, helping you choose the right tool for your needs.

Simplified Production or Detailed Analysis? You Choose.

Both the LEDCure® Profiler and Profiler Four Band support two operational modes:

Display Option: Ideal for fast-paced production environments, this mode provides essential data (W/cm², J/cm², and a low-resolution irradiance profile) directly on the instrument’s display. Single-button operation ensures ease of use, minimizing downtime and maximizing efficiency.
Profiler Option: Designed for laboratory, R&D, field service, and troubleshooting, this mode unlocks advanced analysis capabilities. Data, including the detailed irradiance profile, is transferred to a computer for in-depth evaluation using EIT 2.0’s UV PowerView Software® III.

Unlocking the Power of the Profiler Option and UV PowerView Software® III

The Profiler option, combined with the UV PowerView Software® III, provides a comprehensive platform for UV LED characterization. Here’s what you can achieve:

Comprehensive Data Analysis: Analyze irradiance profiles, energy density, and other critical parameters to understand the performance of your UV LED systems.
LabView Compatibility: Utilizing the LabView (*.tdms) file format, the software seamlessly integrates with all EIT 2.0 Profiling radiometers, including LEDMAP, PowerMAP II, Power Puck II Profiler, and UviCure Plus II Profiler.
Streamlined Data Management: USB download, multiple right-click options, and an enhanced notes section simplify data organization and documentation.
Easy Reporting: Quickly transfer screenshots, profiles, and data tables into reports and other programs, or export data to Excel for further manipulation.
Performance Monitoring: Track the performance of individual sources in multi-array systems, identify changes over time, and address maintenance issues proactively.
Versatile Applications: Analyze different sources, cure conditions, multiple LED arrays, and readings over time, including height and power levels of the LED source, and variations in process speed and exposure time.

LEDCure® Profiler Four Band: The Ultimate Multi-Wavelength Solution

The LEDCure® Profiler Four Band is specifically designed for professionals working with multiple LED wavelengths (365, 385, 395, and 405 nm). Its key features include:

Four Bands in One: Consolidates all four EIT 2.0 L-Bands into a single, portable unit, simplifying multi-wavelength measurements.
Accurate Measurements: Features EIT 2.0’s patented Total Measured Optical Response (TMOR™) for precise and repeatable UV LED measurements.
Easy to Use: Displays individual L-Band irradiance (W/cm²) and energy density (J/cm²) values, along with a low-resolution irradiance profile.
Detailed Analysis: Transfers data and profiles from all four L-Bands to the UV PowerView III Software® for thorough analysis.

Understanding the LEDCure® Profiler Four Band’s L-Bands

The Four Band LEDCure® simplifies the measurement of various LED types with one instrument. Each narrow L-Band (FWHM of 52 nm ± 2 nm) is calibrated to its respective LED type for optimal performance. It’s crucial to note that when using the Four Band, you should only consider the values in the L-Band that matches the source type and not add L-Band values together.

Choosing the Right Tool

LEDCure® Profiler: Ideal for single-wavelength UV LED measurement in production and laboratory settings.
LEDCure® Profiler Four Band: Perfect for those working with multiple LED wavelengths, offering a convenient and accurate multi-band solution.
