Spectra-PT Power Tunable
Spectral Calibration Sources
Simple uniform sourcesof luminance and radiancefor high dynamic range
test and calibration of imaging
and non-imaging devices

Speed and accuracy in a simple design
Spectra-PT sources are designed for flat fielding
and calibrating cameras and sensors for radiometricresponses from low to high light levels. Spectra-PT
yields high fidelity measurements while keeping theuser experience simple and affordable with turnkey
features and excellent dynamic range. A great
all-around uniform source system for simplecamera and sensor testing.
Spectralon®, a highly diffuse material inside
the sphere, provides stable reflectance andrepeatability over the lifetime of the system.
The integrating sphere and control electronics
are housed in a single enclosure for easy portability,and production ready features such as automation, and easy-to-use software interface with user
defined and selectable light levels.
A 13.5 cm integrating sphere with a 5 cm exit port,
precision automated variable attenuator, and built
in photopic response photodetector allows forcontinuous adjustability and good dynamic range
up to 50,000 cd/m2.

Advancing the Technology of Light: Measure. Create. Reflect.

The automated VA allows the user to quickly
and accurately drive to a preset or selectedluminance value. For cameras with wide angle
FOV’s, Spectra-PT features our WAF (Wide Angle
Field Of View) version. Each system comeswith a uniformity mapping and National Institute ofStandards and Technology (NIST) traceable
spectral radiance and luminance calibrations.
