CS SERIESHigh Temperature Sources
The CS Series of cavity type high temperature
blackbodies incorporates three decades of continuous
improvement. EOI infrared sources have set theperformance standard in the most demanding
laboratories worldwide since 1964.
The excellent uniformity, long term stability,
repeatability and high emissivity of the CS Series
provide a known output for testing and calibration of themost sensitive infrared sensors, thermometers, imaging
systems and radiometric devices.
Configuration
The CS Series blackbodies are available in bench top
configuration or integrated into one of the many Target
Projector/Simulators and Automatic Test Stations EOIoffers. Standard cavity sizes from 0.25" to 2.0" cavity
diameters and temperature ranges up to1250 /C areavailable.

Baffle Pate
An air cooled baffle plate is standard with cavities 0.25
inch or larger.
Apertures
Each CS blackbody is equipped with either a manuallyindexed aperture wheel or aperture holder. A water cooled
aperture holder and filter wheels are also available.
Apertures may be added from EOI's extensive list ofstandard apertures. EOI can also supply custom apertures
to meet your requirements.

The CS Series blackbody temperature can be
set manually and feature:Controller
Each CS Series blackbody is supplied with a digitalcontroller. Proportional, integral and derivative (PID)parameters are tuned individually for each blackbody toyield excellent stability (typically ±0.25/C), andrepeatability with fast slew rates and settling times.
Temperature of the blackbody can be set with 1/C
resolution and actual temperature is displayed to 1/C
on the front panel of the controller.

Calibration Each CS blackbody is calibrated at EOIprior to shipment. Recommended calibration cycle is6 months. Calibration is traceable to the National

Institute of Standards and Technology (NIST).
The two point calibration table is stored in memory andis easily updated via the front panel keypad.

Power Requirements
The CS blackbodies operate from 100, 120, 220, or 240 VAC ± 10% (switch selectable), 50/60 Hz. The larger
systems operate on 220V and may require a power amplifier in addition to the controller. Standard cable lengths
between controller and blackbody or controller/output stage and output stage/blackbody are 8 feet. The plug-in mains
power cable is also 8 feet long.
