Consistent light curing requires periodic monitoring of light energy intensity and dosage levels. The ACCU-CAL™ 50-LED radiometer is simple to operate and offers accurate measurement of curing energy. The ACCU-CAL™ 50-LED can measure energy levels emitted from lightguides (3 mm, 5 mm, and 8 mm), BlueWave® QX4™ LED heads, and LED flood lamps. A spectral sensitivity range of 350 to 450 nm and intensity measurement from 1 mW/cm2 to 40 W/cm2, makes this unit ideal for measuring LED curing source energy levels. A specially designed photo-sensor assembly provides repeatable measurements and protection from high temperatures associated with some LED systems on the market.

Complete radiometer with 3 mm, 5 mm, and 8 mm lightguide adapters, lightguide simulator (A lightguide simulator is used to measure direct spot lamp intensity (required to calculate lightguide transmission)), and an optical adapter for use with the BlueWave® QX4™; includes storage/carrying case.

Dymax® ACCU-CAL™ Radiometers

N/A Dymax® offers ACCU-CAL™ radiometers for spots, floods, and conveyors. Kits for spot lamps include the complete radiometer with 3, 5, and 8 mm lightguide adapters and a lightguide simulator. Adapter kits are available separately for users who have an existing flood/conveyor kit and need to use it for spot systems. All radiometer kits include a storage/carrying case. ACCU-CAL™ radiometers are calibrated to measure either UV-A (320 to 390 nm), LED (~ 350 to 450 nm), or visible (395 nm to 465 nm) light intensity.

Radiometer Calibration

N/A Dymax® recommends calibrating the ACCU-CAL™ 50-LED radiometer annually to ensure proper operation of the instrument. Calibration services are available through Dymax®.

Three Reasons to Use a Radiometer

N/A

  • Maintaining a Reliable Light-Curing Process – A radiometer helps to ensure that a light-curing system is providing the intensity and dosage levels required for successful curing.
  • Providing a Worker Friendly Light-Curing Process - The ACCU-CAL™ 50-LED is sufficiently sensitive to measure the intensity of stray or reflected energy (as little as 1 mW/cm2). Dymax® recommends that worker UVA exposure not exceed 1 mW/cm2. For reference, UV (320 to 395 nm) intensity on a sunny day can range from 2 to 6 mW/cm2.
  • Measuring Transmission Rates Through Substrates - A radiometer can be used to measure the transmission rates of various wavelengths through substrates that sometimes absorb various frequencies of energy. To assure an effective curing process it is critical to measure the light intensity reaching the cure site below any intervening substrate.
