International Light Technologies
The ILT350 Spectroradiometer is a low cost, easy-to-use lux and color measurement spectroradiometer with NIST-traceable and ISO 17025-accredited calibration. The device comes with a built-in 12mm-diameter cosine-correcting receptor and a magnetic protective cover. ILT350 has three measurement speeds: fast (0.5 s), slow (2.5 s), and auto (0.5 – 27 s), depending on light intensities. Data is provided in 1 nm increments. Spectral bandwidth is approx. 2.5 nm (half bandwidth) with ±0.3 nm wavelength accuracy. The internal memory can store up to 100 files and export data into both Excel and Word formats.
