Total Flux in W
SED100/F/K15, Larger diode area selected for ease of aiming and assure total flux is measured.
Dynamic 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)
SED033/F/HNK15 Includes a narrow beam adapter to prevent aiming errors.
Dynamic Range: 2e-7 to 3 Watts
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 3e-6 W up to 3 Watts.
(Note: add QNDS1, QNDS2 or QNDS3 to attenuate by a factor 10,100 or 1000 as needed)
Radiance in W/cm2/sr
SED033/F/R Narrow field of view, radiance probe. Field of view: 1.5 deg. Designed for average measurement of radiance over a target area greater than 30 mm diameter plus 0.75 degree half angle.
Dynamic Range: 6e-8 to 1e+0 W/cm²/sr
Measurement Range: 400-1064 nm
Dimensions: 87 x 42 mm dia.
