Filter Definition File Description - FLIR X8400sc User Manual

5.1.6 Filter definition file description

General Filter definition files contain identification and spectral information for the corresponding filter.
This information is used by the camera and ResearchIR Max to adjust measurement
configurations.
Filter definition files must contain all the sections described hereby. Values in section must
not be longer than the specified number of characters. It may be easier to copy an existing
filter file and modify it.
The file structure is described hereby. The text in bold is given as an example.

User Manual X8400 sc
Filter
²
The reference of the filter. This reference is used in the
Slot.ini file and must start with the capital letter F.
The user friendly name which is displayed on the LCD
GUI and ResearchIR Max user interface. FLIR ATS
uses the following naming convention, but it can be
freely modified.
XX_YYYY_ZZZZ_WW%
•
XX : Type of filter (NA : Narrow, LP: Low Pass,
HP: High Pass, BP: Band pass)
•
YYYY : Cut on in nm
•
ZZZZ : Cut off in nm
•
WW : Average Transmission
Application in which the filter is used
BB : Broadband midwave (1.5-5µm)
