Components for Spectroradiometric Systems

USB4000 Fiber Optic Spectrometer

Our USB4000 Spectrometer can be optimized for LED measurements from 350-1000 nm. Specify a 25 µm entrance aperture and an L2 Collection Lens to increase light collection efficiency.

USB4000: $2540

LED Power Supply

The LED-PS Power Supply provides three useful functions: holding the LED in place, powering the LED and displaying the LED's drive current. Use the adjustable drive current feature to increase or decrease and LED's current up to 50 mA. The LED-PS-NIST is a NIST-traceable version.

LED-PS: $577
LED-PS-NIST: $866

Integrating Sphere for 360° Emission Collection

Powered by the LED-PS Power Supply, the LED is inserted into the 9.5-mm diameter port of the FOIS-1 Fiber Optic Integrating Sphere, which has a 360° field of view. A P400-2-VIS-NIR Optical Fiber collects the light from the FOIS-1 and delivers it to the USB4000 Spectrometer.

FOIS-1: $646

Radiometric Reference Sources

The LS1-CAL-INT is a NIST-traceable light source designed specifically to calibrate the spectral response of a spectroradiometric system that uses the FOIS-1 as a sampling device. It provides known absolute intensity values at several wavelengths. The LS-1 is used as a reference for relative power measurements.

Cosine Correctors

Our Cosine Correctors collect radiation with a 180° field of view. When used in a fiber coupled to a spectrometer, they measure light intensity at the surface of the probe.
