Spectroradiometer 200 - 450 nm and 250 - 1050 nm

ILT950 / ILT950UV from International Light Technologies
The ILT950 is equally at home on the production floor as well as in the laboratory combining high performance, accuracy, ease of use, and a wide array of features all in a rugged, compact, portable design. The excellent performance of the ILT950 has been improved further with the addition of a new machined optical bench for reduced stray light and improved thermal stability. The ILT950 and ILT950UV spectroradiometers also now use the new higher pixel SONY CCD array for improved performance including nearly 50% more sensitivity over the entire spectral region, and higher S/N ratio increased from 200:1 to 300:1 with larger quantum well depth. These improvements combined with the new features in our powerful SpectriLight III software, including PAR μmol/m²/s, metamerism, and baseline overlay comparisons, make the ILT950 a top performer in the CCD array spectroradiometer market.Features
  • NIST-traceable, ISO17025 accredited calibration
  • UV-VIS-NIR-Range
  • Resolution: 1.4 nm with 25 micron slit
  • Focal length: 75 mm
  • Symmetrical Czerny-Turner

Further information

SpectriLight III – ILT550 and ILT950 series control & analysis software SpectriLight™ III is a LabVIEW based software package for Windows that allows you to acquire spectral and color data. The new version of SpectriLight™ III has additional calculations for metamerism, and 2 and 20 degree
observer. The new overlay feature allows the user to compare the base reading to current readings. Wavelength range, integration time, scan average and other controls can be easily set through pop up windows, menus and tool bars. Absolute irradiance and chromaticity are calculated instantly. SpectriLight™ III is LabVIEW based software and can be easily customized for specific OEM applications. For API applications, Multiple DLL’s are available. Specifications

Optional input optics
ILT-R2 Radiance optic
Specialized fiber optic produces an average field of view of 2 degrees
for radiance/luminance measurement of extended sources. Requires ILTVS950R calibration.
ILT-RAA4 Right angle cosine adapter
with approx. 6.9 mm diameter aperture, permits measurement of light sources 90º to the standard fiber. Sold with weighted screw-on handle for more stable detector placement when needed. Excellent cosine response, increases signal transmitted to CCD spectrometer, excellent for lower light, low profile, and small diameter light pattern measurements. Calibration required (sold separately).

ILT-INS50 2-inch Integrating sphere
with 2 ports; SMA905 and 5 mm port with lambertian response. For testing mounted and unmounted LEDs, fiber optics and miniature lamps. Provides readout of total flux in watts and lumens, irradiance in W/cm2, illuminance in lux, color purity, spectral distribution and color temperature with ILT550 (requires ILT-VS950P calibration). Alternative: ILT-INS125 5-Inch Integrating sphere and ILT-INS250N 10-inch Integrating sphere.

ILT-FFOSMA2UV1000
2 meter long, 1000 micron, armored fiber optic light guide. Transmits light from 250 -1050 nm. Strong armored cable adds additional protection against breakage often required for longer fiber lengths.
Real-time analysis
  • Irradiance: Total, Visible, UVA, UVB, UVC, PAR and photopic data
  • Selectable bandwidth for irradiance, power and radiance (requires additional hardware and
    calibration options)
  • Chromaticity analysis: x, y, u, v coordinates and display in CIE color spaces
  • Dominant and complementary wavelength and color purity
  • General Color Rendering Index (CRI) and 15 special color rendering indices
  • Correlated Color Temperature (CCT) and DUV
