1.5. Operation of Blue-X-Lite
WARNING!
Risk of injury due to optical radiation: Risk Group 2 acc. EN 62471:2008
Looking directly into the light of the Blue-X-Lite can cause eye damage if the
duration of the eyelid closure reflex of 0.25 s is exceeded. Under real circumstances
(for exposure time, conditions of the eye pupils, observation distance), it is assumed
that no endangerment to the eye exists from these devices. As a matter of principle,
however, it should be mentioned that intense light sources have a high secondary
exposure potential due to their blinding effect. When looking at bright light sources
(e.g. headlights), temporary reduction in visual acuity and afterimages can occur,
leading to irritation, annoyance, visual impairment, and even accidents, depending
on the situation.
•Before switching on, make sure that no person is in the light beam of the
lamp and can be blinded by it!
•Do not look directly into the light of the Blue-X-Lite!
•Always turn down the intensity of the Blue-X-Lite during setup and
adjustment so that the user is not blinded!
•Always use the enclosed safety goggles while handling the Blue-X-Lite
during installation and operation!
Risk of epileptic shock
Stroboscopic light can trigger seizures in photosensitive epilepsy.
•Do not use the device in the presence of persons who are at risk of
epileptic attacks!
Risk of burns when touching the Blue-X-Lite
Depending on the ambient temperature, the housing and lens of the Blue-X-Lite
can become very hot during longer operation. Touching the Blue-X-Lite can cause
slight burns in this case.
•Always allow the Blue-X-Lite to cool down before touching it!
•Never use a Blue-X-Lite with a damaged lens.
•Under any circumstances keep the minimum safety distance(s) given in the
technical specification to avoid damages caused by light beam(s) and / or
thermal radiation and / or heat radiation to person(s), animal(s) and / or item(s)
and / or object(s).

Page 7 of 18 Blue-X-Lite V1 © isi-sys GmbH 2023 Rev.:23/10/2023
•In the case of a defect or damage of the lens (particularly while it is in operation):
switch of the power supply immediately, disconnect it from the power socket,
let it cool down completely and contact isi-sys for replacement of the lens.
•Never use a Blue-X-Lite unattended.
•Always disconnect the power supply from the power socket if it is not in use or
in operation.
•In the case of overthrowing, falling down and/or jarring heavily a Blue-X-Lite has
to be checked by isi-sys for damages
1.6. Maintenance
NOTICE!

2. Blue-X-Lite
The Blue-X-Lite is a light source specially developed for Digital Image Correlation (DIC). The short
wavelength and low bandwidth blue light improves the optical transmission function of lenses and
reduces chromatic aberrations and diffraction, especially in high-resolution setups with a small field
of view. The Blue-X-Lite is an entry-level, cost-effective professional flicker free lighting solution for
digital image correction. Its compact design offers a practical solution that can be easily attached
directly to the stereo bar. The passive cooled fanless design offers the advantage of no vibrations
transmitted to the stereo bar.
The Blue-X-Lite can be used in continuous operation or in pulsed operation with 20 W. Due to its
fast rise times < 100 ns in combination with special trigger unit it is also suitable for synchronization
with DIC high-speed systems for frame rate up to 10.000 fps with stroboscopic illumination. Two
versions are availed with trigger frequency up to 1000 Hz or 10.000 Hz.
Variable focusing allows a beam angle from 5° to 60° - removable and interchangeable lenses
provide for small to large FOV, same as the Blue-X-Focus. The Blue-X-Lite can be equipped with a
polarization filter with adjustable polarization direction to reduce direct reflections.

2.1. Technical description
The Blue-X-Lite can be synchronized with DIC-Systems through a trigger device e.g. ATB-V or DAQ
and can be triggered up to 10.000 Hz (1.000 Hz) in pulse mode. Two Versions are available with
trigger limit of 1.000 Hz or 10.000 Hz. The power of the LED is adjustable via a rotary knob on the
back of the device. It is equipped with passive cooling and an integrated temperature safety
shutdown. The device can be mounted directly with a camera mount to the stereo bar and the
focusing option of the light allows to adjust the light beam from spot up to flood light characteristic.
Simply turn the lens tube to adjust the size of the light beam diameter precisely. The Blue-X-Lite is
designed for 12 VDC with power supply (110 230 VAC, 50/60 Hz) and is equipped with one 20 W
high power single cell LED and generate a flicker-free light.
2.2. Characteristics of the Blue-X-Lite
Stepless intensity control with power switch
The Blue-X-Lite can be switched ON and OFF with the 12 V power supply via the power switch
integrated in the rotary knob. The light intensity can be controlled stepless using the rotary knob.
Recommended intensity adjustments within the operation limits are 0.5- 60% light intensity for
continuous wave mode (CW). For pulse mode 0.5- 100% light intensity is possible.
Operation mode switch for continuous wave mode (CW) or pulse mode (Pulse)
Using the Operation mode switch, change the operation mode from continuous wave mode (CW)
to pulse mode (Pulse) or vice versa. Please check whether the operating limits are within the
permitted range before switching. Operating limits are specified in section 2.6.

DC Input
The included 12V DC switching power supply is connected to the DC input via the power cable.
BNC Trigger Input (TTL)
For operation in pulse mode, connect a trigger source with a TTL level signal via a BNC cable. A
synchronization with the image acquisition of DIC system can be done via this trigger input. We
recommend special trigger devices from isi-sys GmbH.
Optional Polarization filter
The optional attachable polarization filter can be used to reduce direct reflections in combination
with a camera where a polarization filter is attached as well.
Focus locking screw
After setting the illumination range for homogeneous illumination via the focus of the light source,
it can be fixed with the Focus locking screw
Threads for mounting
For mounting on a tripod, beam or adapter plate, there are several options with 1/4" threads
thread or M6 on the bottom of the case. -X-Lite to a camera mount
designed by isi-sys GmbH.
2.3. Exemplary setup scheme
The Blue-X-Lite can be operated standalone in continuous wave mode when connected to the power
supply through the power supply cable. To operate the Blue-X-Lite in pulse mode, the Blue-X-Lite
must be connected to a trigger device (TTL Signal). The Power is adjustable manually or external by
pulse length and frequency. The Blue-X-Lite can be synchronized with a camera system via the
trigger unit.
For installation and operation note and obey the safety instructions in section 1!
