Introduction
The EIT® LED-R™ Series of instruments is a new family of instruments with optics designed for the measurement of UV LEDs. The instruments build on EIT’s
32+ years of UV measurement experience and previously released products that have bene used to measure broadband UV sources. The first products
released are LEDCure Radiometers in Profiling and Non-Profiling (Standard) versions.
The EIT® LED-R™ Series of instruments feature a Total Measured Optics Response.
The LEDCure builds and improves on the success of previous EIT radiometers, instruments which are widely used for accurate, repeatable UV measurement of
broadband sources throughout the global UV industry. The LEDCure features selectable sample rates, reference modes and UV irradiance profile graphs. The
new instrument is designed specifically to measure UV output from industrial UV LED light sources. As with other EIT products, the instrument is simple to use
with easy push-button operation.
The LEDCure is a self-contained, electro-optic radiometer that measures and displays the total UV energy and UV irradiance of a UV LED curing system. The
LEDCure combines compact size and robust design to withstand the extremes of UV LED curing environments while providing accurate measurements.
The carefully engineered optical sensing systems only measure LED wavelengths that are relevant to the UV process in the LED band specified. The output of
the sensing system is converted to digital form and displayed on an easy-to-read OLED display.
The LEDCure provides measurement from a choice of one of the available EIT wavelength bands designated LXXX, where XXX is the center wavelength of the
source to be measured in nanometers (e.g. the LEDCure Model L395 measures 395nm center wavelength LED sources).
EIT Instrument Markets LEDCure is manufactured in the USA. Patent Pending.
The Process Values
The two process values read by the LEDCure are total energy and peak irradiance. The irradiance reading is instantaneous and is the highest amount of UV
energy that the unit senses during an exposure run. The irradiance value is energy at one instant in time during the exposure run. The radiometers measure
and display irradiance in Watts or milliWatts per square centimeter (W/cm2, mW/cm2).
Total energy density (sometimes referred to as “dose”) is a factor of irradiance over time. The instruments derive this value from the irradiance values during
the exposure run and the length of time of the run. Total energy is measured in Joules or milliJoules per square centimeter (J/cm2, mJ/cm2).
Reaching the energy and irradiance values specified by your process is necessary for achieving a complete UV cure.
Ultraviolet Radiation
Although this product is not a source of UV light, it is used in a
UV environment. Refer to the UV source's documentation for
recommended protective measures against UV radiation present
in the UV environment.
