CDS100 Differential
Temperature Sources
The EOI CDS Differential Temperature sources
create precise, adjustable thermal contrast patterns
primarily used in testing and characterization of IR
imaging systems.
The CDS Series features set point resolution of
0.003°C. These exceptional capabilities enableaccurate evaluation of the most sensitive IR systems.
Configuration
These sources are available in a stand alone
configuration or integrated into one of the many Target
Simulators and Automatic Test Stations EOI offers.
Source sizes (target area with 15°FOV) range from
1.8O× 1.8O to 18O× 18O.

Controller
Each Commercial Differential Source is supplied with a19" rack mount digital controller. Operated manuallyfrom the front panel keypad or automatically using any of
the four built in computer interfaces, this versatile
controller also controls all optional equipment.
Calibration
Each CDS100 System is calibrated at EOI prior toshipment. Recommended calibration cycle is 6 months.
Calibration is traceable to ITS-90 via the National
Institute of Standards and Technology (NIST).
Calibration tables are stored in memory and are easily
updated via the front panel keypad.
Slew Control
A remote hand held controller box is included which may
be used to facilitate observer optimization whilemeasuring MRTD.

Targets
An extensive list of standard four bar, slit andcircular targets is available. EOI also supplies
custom targets. Custom targets can be any patternwith a minimum dimension of 0.001"(.025mm).

OPERATIONAL MODES

Effective Differential Mode
Compensation for emissivity differences or losses inadjunct optical systems so that zero differential
temperature corresponds to zero radiometric contrast.

Differential Temperature Mode
Temperature control of the thermal contrast between
controlled surface (source) and target.

Computer Interfaces
Complete computerized control of the system is available
through built-in interfaces.

Absolute Temperature ModeControl of source at absolute temperatures.
