The ILT5000 radiometer is the ILT1700 for the 21st Century! Improvements on the industry standard ILT1700 include rapid optical measurements (1-100hz), a broader dynamic range (100fA to 1mA), Datalight III for PC and Mac, plus built-in wireless, data storage, and rechargeable batteries.

The ILT5000 is backwards compatible with the ILT1700 sensor configurations, as well as all of ILT's sensor accessories including filters, optics, integrating spheres and ISO/IEC 17025:2017 Accredited/NIST traceable calibrations.

ILT manufactures the ILT5000 and DataLight III radiometer in the USA at our Peabody, MA facility which allows us to rapidly customize system components to meet the needs of our customers and OEMs.

ILT5000 optical measurement systems typically consist of the ILT5000 light meter, a sensor, filter, optic and calibration to allow direct reading in the appropriate empirical units including lux, foot-candles, candela, lumens, watts, W/cm2, cd/m2, foot-lamberts, nits, etc.

Measurement systems: The ILT5000 meter requires a sensor to measure light. Sensors are available to measure from 185 nm out to 40 micron and are supported with a vast array of accessory including bandpass filter, cosine receptors, integrating sphere, and numerous types of calibration.

ILT800 CureRight Radiometer Series
ILT800 CureRight Radiometer Series
Manufacturer: International Light Technologies

Wavelength 215-475 nm; Range 4.5 decade (mW/cm2 to 40W/cm2); Temperature 0-75 °C (internal case temperature)The ILT800 CureRight is a UV curing radiometer that is packed with features, offering unparalleled flexibility and capabilities not found in any other system. Its adaptability enables the device to measure lights used for UV curing and a variety of other applications such as sterilization/disinfection, lithography, and more. The system is designed with the diverse needs of its users in mind and can be tailored to fit your specific environment.The ILT800 CureRight series validates and measures all kinds of UV curing methods and sources, including conveyor, belt, oven, flood, area, spot, fiber optic, collimated beam, side cure, 180° curing, 3D printing, pulsed and traditional UV lamps, and UV/VIS LEDs & light sources.The ILT CureRight is available in five standard configurations:ILT800-UVA: 315 - 390 nmILT800-BAV: 275 - 475 nmILT800-UV: 250 - 400 nmILT800-CUV: 215 - 350 nmILT800-UVF (UV LED): 360 - 400 nm Flat, (275 - 450 nm)Contact us for OEM / Custom FiltrationThe ILT800 CureRight UV radiometer system surpasses competitors with features like standard profiling and programmable settings such as measurement modes (auto/manual/live), minimum light level threshold, and lamp-to-lamp measurement interval (delay). The system also boasts a unique user interface that places the input sensor and optic, device controls, and the readout display all on one side, facilitating simultaneous measurement, monitoring, and analysis of measurement data.The ILT800 UV radiometer allows users to track their curing processes over time by allowing them to store, download, and view both current and all previously saved readings on the device’s integrated OLED display. This built-in data storage and review feature enables users to quickly identify changes that have occurred over time. It also helps users to easily spot potential issues in their systems such as dirty lamps and reflectors, lamp/reflector misalignment, declining lamp output, failed lamps, and power supply problems, among others. Additional benefits include the ability to download the results to a computer for more detailed analysis. With ILT’s proprietary DataLight CureRight software interface, users can download and view their data, as well as generate spreadsheets and reports using their own analysis tools.To further enhance the data storage and capabilities, ILT introduced an advanced sorting feature called Device ID, a feature not found in any other UV curing light meter. Device ID allows users to program up to 20 unique system/light source name tags. Device ID enables users to view and export all saved data for each curing station or light source into separate files, clearly identified with the Device ID. It’s like having the functionality of multiple meters in a single device.The ILT800’s spectral filtration was designed to match the photoinitiators’ response to UV light, which is directly related to its absorption and is highly wavelength selective. Most lamps emit broadband UV/VIS/IR, and the lamp’s output may not change evenly across all wavelengths. The ILT800 filters were designed to monitor changes in output in the areas that affect absorption, and consequently, the effectiveness of the curing. Whether you’re using a low-output fluorescent source for sterilization, high-intensity mercury or xenon lamps for curing, or narrow-band LEDs for photolithography, there’s a version of the ILT800 tailored for your needs.Filtration options covering UVC to UV-VISFiltration to ensure a process matchMeasures only the light that effects the cureApplications: low-output fluorescent sources for sterilization, high-intensity mercury or xenon lamps for curing, narrow-band LEDs for photolithographyPlease note that International Light products are available from us only in Denmark, Finland, Iceland, Italy, Norway, and Sweden.
