Description
The document describes the X1-1 radiometer by Gigahertz-Optik GmbH, designed for measuring irradiance in UV-A and blue light radiation curing processes. These processes involve the use of high-intensity UV-A and blue light to activate photoinitiators in liquids like inks and adhesives, triggering polymerization. Traditionally reliant on gas discharge lamps, these processes are increasingly using LEDs. The X1-1 radiometer, equipped with an RCH-116-4 detector, measures irradiance levels up to 40,000 mW/cm² and features a passive radiation absorber for stability in high-temperature environments.

Specifications
The X1-1 is a handheld radiometer with a separate detector for high-power LED lamps in UV-A and blue light curing. It has a measurement range from 1 mW/cm² to 40,000 mW/cm² and is calibrated for LED wavelengths of 365 nm, 375 nm, 385 nm, 395 nm, 405 nm, and 430 nm. The device supports continuous wave (CW) and dose measurement functions and can be remotely controlled via user software.

Calibration
The RCH-116-4 detector is calibrated for standard LED wavelengths, with calibration performed by Gigahertz-Optik’s DAkkS-accredited laboratory. Calibration ensures precise and traceable measurements, confirmed by a calibration certificate.

Purchasing Information
The document lists product numbers for the X1-1 instrument, RCH-116-4 detector, and accessories like a hard case and calibration services. Software options include user software and a software development kit for custom software integration.

Applications
The radiometer is used for monitoring and regulating LED emitters in UV-A and blue light radiation curing, ensuring optimal polymerization by maintaining consistent irradiance levels.
