2-3-3 Lens
Prepare a lens compatible for objective performance for magnification rate, field of view and mount
the lens to the front panel of EHD-SWIR series.
 Mount type of lens: C-mount
Caution: In mounting a lens, do not screw it by more than 10 mm in the flange of C-mount. Too much
screw-in could result in damage of FPA.

4 Operation
4-1 Start-up
(1) After making sure of connections between EHD-SWIR series, cables and the frame
grabber, switch on the PC and power supply.
(2) Start to supply +24V to EHD-SWIR series by the power supply.
(3) Wait for about 5 minutes for stabilization.
(4) Execute a sample software for image capture of an attached CD in the PC. The camera
setting, image capture and monitoring can be done by the software.
Regarding how to use the above software, refer to “user’s guide of sample software for image
capture” in the attached CD.
4-2 Shut down
(1) Stop the power supply.
(2) If EHD-SWIR series will not be used for a long time, it is recommended that the plug is
pulled out from the AC outlet.
4-3 External trigger input
EHD-SWIR series can capture images by not only its inner clock but also an external trigger. Its
circuit has an input insulated by photo couplers. Every rise to DC +24V in the trigger signal
executes one shot at the exposure time at current setting.
4-4 External alarm output
Not only to monitor inner status of EHD-SWIR series but also to output alarm from it can be done
by the software. Its circuit has an open collector insulated by photo couplers. When any error
occurs in EHD-SWIR series, it makes output pins short-circuited.

5 Maintenance
5-1 Camera body
In cleaning the camera body, remove the cables from it and attach the lens cap to the lens
mount. Cleaning the body with cables connected could result in electric shock. Use a cloth which
hardly generates dust such as nonwoven fabric. Do not use alcohol, thinner, benzene and strongly
acid or alkaline chemicals for cleaning.
5-2 Air filter
When the air filter at the rear panel of E H D -SWIR series is soiled and blocked, take it off
together with a retainer as shown in Figure 8 and make it clean. If the air filter is dirty so that it
should be exchanged, make contact with us.
