UV energy for industrial applications has historically been generated by mercury/mercury-additive based lamps using arc or microwave technology. UV generated by mercury sources is "broad band" with output across the ultraviolet, visible and infrared spectrum. UV LED sources generate UV in a relatively narrow band. Power levels, spectral choices available, LED features and the form factor of the equipment have allowed LEDs to be used in new UV applications and in some cases be used in place of broadband UV technology.
EIT has developed a line of LED UV measurement instruments specifically designed and engineered with a response (L-Band) to accurately, reliably and repeatability measure industrial UV LEDs. EIT LED radiometers are NIST traceable and are available in different LED specific responses or L- Bands.
- EIT’s LED products feature a patented L-Band (365, 385, 395 and 405) response optimized for UV LEDs and superior performance
- Radiometers provide calibrated irradiance (W/cm2) and energy density values (J/cm2) in one to four L-Bands
- Profiling Radiometers also provide the irradiance profile (W/cm2 as a function of time)
The Importance Using an EIT L-Band to Measure UV LEDs
- The L-Bands (L-365, L-385, L-395, L-405) have been designed specifically to measure UV LEDs.
- Each L-Band response is designed to accurately measure the Center Wavelength variation (+/- 5 nm) of an LED.
- LEDCure L-Band instruments feature a patented "Total Measured Optic Response".
- ALL optical components in instrument stack are included in the instrument response. This results in repeatable and accurate absolute readings:
- EIT instrument-to-instrument
- EIT LEDCure instruments have a dynamic range that supports UV LEDs
- EIT offers responsive ongoing technical support. You can reach EIT staff via telephone or email (email@example.com) and receive prompt support and help.
