Cavity Blackbody Sources

EOI provides a large selection of high temperature cavity blackbodies and has built thousands of specialized blackbodies from vacuum chamber sources to airborne calibration sources.

Visible Integrating Spheres

EOI's visible light sources are used as general laboratory instruments or as precision calibration sources for detectors which respond to visible light.

Differential Sources

EOI's differential temperature sources provide precise, adjustable thermal between a target and the background.


Extended Area Sources

EOI provides a large selection of large area blackbodies which cover the range from low temperature small area to high temperature large area sources.

Collimators and FLIR Test Sets

The EOI LC series of high resolution, reflecting collimators are used to provide a collimated source of infrared or visible energy to a system under test.

Test Targets

Four bar patterns or "targets" are the most commonly used standard in determining the performance of infrared imagers.


Standard Freezing Point Blackbodies

The EOI series of primary standard blackbodies are pure elemental freezing point blackbody radiation sources for use as primary standards of spectral radiance.

High Accuracy Thermometers and Calibration Kits

EOI's precision thermometers are used as general laboratory instruments or as calibration thermometers for EOI's infrared sources.

Precision Radiometers and Spectral Radiometers

EOI produces a number of general and application specific radiometers to detect and measure the intensity of radiant energy.


Complete Turnkey Systems

EOI designs and produces custom equipment and we provide solutions for the customers' testing needs based on EOI's standard products.

EOI has built thousands of specialized systems ranging from vacuum chamber sources and airborne calibration to complete testing stations for visible, infrared, and ultra-violet applications.

Precision Apertures

Apertures are used to limit the amount of energy flux emitted by a blackbody. EOI offers an extensive list of precision apertures.

EO Testlab Software (PDF file)

EOI’s TestLAB Software creates a new standard in testing electro optical systems utilizing industry standard methodology.

EO TestLAB is used in several government facilities collecting and formatting data into easy to comprehend reports.

Combined with EOI enhancements, it ensures accurate test data.
