ISP-I Integrating
Spheres
ISP-I Integrating Spheres are convenient sampling optics that couple to our spectrometers and optical fibers to measure the spectral output of LEDs, lasers and other light sources from 200-1100 nm.
Features
-
Spectroradiometric
Analysis. Couple spheres to
spectrometers to analyze LED, laser and light source output
-
Flexible. Spheres are available in
diameters of 30 mm, 50 mm and 80 mm
-
LED-ready.
Spheres accommodate a variety of LEDs
-
Direct-attach
option. Spheres
can couple directly to a spectrometer
Each fiber optic integrating sphere consists of a proprietary PTFE-based, sintered diffusing material -- in diameters of 30 mm, 50 mm or 80 mm -- that provides a Lambertian surface (with >98% reflectivity in the visible) for irradiance measurements. Sample port sizes of 6 mm (for the 30-mm sphere) and 8 mm (for the 50-mm and 80-mm spheres) are available.
LED Measurement Option
The ISP-I-50-8 50-mm Integrating Sphere can be used with an adapter (ISP-LED-ADP) that will accommodate 3 mm, 5 mm or 8 mm LEDs, holding the LED in place to ensure reproducibility. (The adapter screws into the sphere’s sample port; a
setscrew secures the LED.)

Measurement System.
Direct-attach
Option
The ISP-50-I-USB and USB-ISP-80
are irradiance/emission integrating spheres that can be directly attached
to a USB4000 (and USB2000 Spectrometer (spectrometers sold
separately) to measure the spectral output of LEDs, lasers and other light
sources.
Each direct-attach integrating sphere consists of a proprietary PTFE-based, sintered diffusing material -- in diameters of
50 mm or 80 mm -- that provides a Lambertian surface (with >98% reflectivity in the visible) for irradiance measurements.
Each sphere features an 8-mm sample port.
Calibrated Source
Also available is a NIST-traceable calibrated tungsten halogen light source, the
HL-2000-CAL-ISP, that’s designed for use with the ISP-50-8-I Integrating Sphere. The
source is calibrated for the VIS-NIR (360-1000 nm), and sits directly atop the integrating sphere.
