Description
Hyperspectral Imaging
Hyperspectral imaging combines digital imaging with spectroscopy, detecting the unique spectral information in
each image pixel. It can be used to identify, measure, and locate different materials and their chemical and physical
properties.
Compared to the conventional visible light imaging, both monochromatic and color, hyperspectral imaging produces
much more detailed information with an expanded wavelength range, also recording the data invisible to the human
eye, to be computed and analyzed.
Pushbroom imaging technique
SPECIM FX cameras use pushbroom line scanning technique, which means that the target is scanned one spatial line
at a time and full spectral data from that line is aqcuired simultaneously.
Using pushbroom technique always requires that either camera or the target moves and the movement builds up
the image. The movement can be achieved for example by mounting the FX camera to a scanner, vehicle, or over a
conveyor belt.
Illumination Overview
In spectral imaging, good illumination plays a bigger role than in conventional digital imaging. When arranging
illumination, pay attention to three main parameters: intensity, spectral response and uniformity.
Intensity
Hyperspectral imaging needs more light than ordinary machine vision system as the light is divided to narrow
wavelength bands and each band is measured separately. As a result, each pixel receives less light during fixed
integration time than, for example, in RGB color imaging and the illumination used for hyperspectral imaging is
brighter than the illumination used for standard cameras. The need for light can be partly compensated by using
longer integration (exposure) times, but at the same time the measurement becomes slower.

| Description | 6
Spectral response
Illumination for hyperspectral imaging must always have a continuous spectrum that covers the full wavelength
range, over which the hyperspectral camera is operating. If the illumination does not have signal in some of the
wavelengths, the measured data on those wavelengths is not valid.
The recommended options for Specim FX are halogen-based and sunlight illumination solutions.

| Description | 7
Uniformity
Another important illumination parameter is the uniformity of the illuminated area. The light coming for each position
of the imaged area should have the same spectral response and intensity. There should be neither no shadows nor
specular reflections, in the illuminated area. It is always better to use several, preferably two or four light sources
instead of one, to illuminate the area.
Camera Overview
FX10 camera series is built around the monochrome CMOS image sensor that provides a resolution of 1312 x 1082
pixels at a wide range of spectral sensitivity. It is aimed at standard applications in industrial and laboratory image
processing. FX10 cameras work in a push-broom mode, and collect hyperspectral data through single fore optics.
There are four versions of the FX10 camera:
• FX10, CameraLink, 400-1000 nm
• FX10e, GigE, 400-1000 nm
• FX10c, CameraLink, 400-780 nm
• FX10ce, GigE, 400-780 nm
These specifications apply to all FX10 camera versions.
Figure 4: FX10 Spectral Camera
The standard lens for FX10 is OLET15 with 38° FOV and 150 mm focusing distance. The filter thread for the
standard lens is M43x0.75. The camera is always delivered with a lens cap. We recommend you use the lens cap
whenever the camera is not in use.
Checking the camera version
The first digit of the camera serial number tells the version of the camera. The serial number can be found from the
camera status line. For more information, see Status Line section of this manual and ASCII for FX -series document.
Serial number Camera version
1xxxxxx FX10
2xxxxxx FX17
3xxxxxx FX10e
4xxxxxx FX17e
5xxxxxx FX10b
6xxxxxx FX10be
7xxxxxx FX10c

Serial number Camera version
8xxxxxx FX10ce
Firmware version and updater
With the new revision of FX-series it is now possible to update the camera firmware via software updater on-site with
the software package provided by Specim.
Note: It is not possible to use this feature previous revision’s FX-cameras without hardware changes.
See the camera's serial number to check if your camera belongs to the new revision: the third digit of the old revision
is xx0xxxx, while the new revisions' serial number is xx1xxxx.

A diagram of the camera data path is shown in the figure below.

Image Correction
The camera includes the following image corrections:
• Offset and hot pixel correction
• Automatic Image Enhancement (AIE) means that spectral calibration will be the same for every FX camera, and
that smile and keystone will be corrected to practically zero for all cameras.
A customer with several cameras can replace one camera with another and still have the same spectral calibration
and smile/keystone without additional calibration.
All rights reserved - Specim, Spectral Imaging Oy Ltd.

| Description | 9
All the corrections are enabled by default.
Regions of interest
The image sensor in FX series cameras is larger than the actual image size. Therefore the image area on the sensor
is defined using the Region of Interest (ROI) feature, and the ROI values are provided in the calibration pack. ROI
feature is reserved for this purpose alone, and the values must not be changed.
You can use Multiple Regions of Interest (MROI) feature to define one or several regions of interest. Using MROI
feature requires 1 x 1 binning.
If you use AIE together with MROI, there must be additional 3 rows in the beginning and in the end of each MROI to
prevent corruption. These extra rows must then be discarded in data processing as their data may be invalid.
External Interfaces

There is one Fischer Connector DBPLU1031Z012|130G in the camera back panel.

Software Options
Lumo Software
Lumo is a family of software products for hyperspectral sensor data acquisition.
• Lumo Recorder, for when there is no Specim scanner used in the setup
• Lumo Scanner, for when there is a Specim scanner in use
With Lumo Software you can select camera and scanner, adjust acquisition parameters, and save raw data of the
camera. It can also control other external devices, required for certain sensors, such as thermal calibrator, triggering
electronics, motors, and so on.
Lumo Software has a built-in scripting and sequential workflow engine controlling all the steps and automation to be
performed for each measurement.
For instructions on how to use your Lumo software, refer to the relevant Lumo Software User Manual.
SpecSensor SDK
SpecSensor SDK is a unified SDK for all our cameras, and it is typically used by OEM and integrators. C style API
can be used from different programming languages.
SpecSensor SDK sends commands to cameras and gets the frames from the cameras, however it does not have a GUI
or record data to the disk.
For instructions on how to use your Specim SDK, refer to the SpecSensor SDK User Manual.
ASCII Commands
the Camera Link version of the FX camera can be controlled with ASCII commands, for example in cases where
hyperspectral imaging is integrated in an existing ASCII based system or when required features are not supported by
LUMO or LUMO SDK Software.
ASCII commands are available in separate ASCII documentation. Note, that Specim does not provide support
packages for ASCII use cases.
GigE Vision
GigE version of the FX camera is complient with GigE Vision interface standard, which is a global standard for
video transfer and device control over Ethernet networks. For more information, refer to GigE Vision Standard
Specification.
