ILT's "F" Filter provides a nearly flat response over the 400-1000 nm range when combined with ILT's silicon sensors. This flat response allows the ILT5000 and sensor to measure many different wavelengths of lasers, diodes and collimated sources. Neutral density filters can be added to attenuate the signal by a factor of 10 to 1000.

Most commonly sold system configurations:
ILT5000, SED100/F/K15, Larger diode area selected for ease of aiming and assure total flux is measured.

Measurement Range: 7.69e^-13 to 1.5e^-2 Watts
(Note: add QNDS1, QNDS2 or QNDS3 to attenuate by a factor 10, 100 or 1000 as needed)

ILT5000, SED033/F/HNK15  Includes a narrow beam adapter to prevent aiming errors.

Measurement Range: 4e^-9 to 3 Watts
(Note: add QNDS1, QNDS2 or QNDS3 to attenuate by a factor 10, 100 or 1000 as needed)

ILT5000, SED033/F/HMR/HNK15 (HMR filter added to block the IR wavelengths above 700 nm)
Measurement Range: 3.5e^-10 to 7 Watts
(Note: add QNDS1, QNDS2 or QNDS3 to attenuate by a factor 10, 100 or 1000 as needed)

ILT5000, SED033/F/INS125 or SED033/F/INS250. The INS125 5” integrating sphere and INS250 10” integrating sphere allow total flux measurements from sources that are larger than the active area of the SED100 and HNK15.  This include small lamps, lasers, laser diodes and other light sources.  Our Integrating spheres have two ports for connecting the light source (one 20 mm dia port and one 40 mm dia. Port).  Average power measurement ranges cover from 4e^-9 W up to 3 Watts.
(Note: add QNDS1, QNDS2 or QNDS3 to attenuate by a factor 10, 100 or 1000 as needed)
