1. Safety and Operation Instructions for Blue-X-Focus • Before the system’s initial operation, read the operating instructions carefully and pay particular attention to the safety instructions. These contain important information for your protection. • Save these documents together with the technical brochures and accessories for later reference.
The Blue-X-Focus is used exclusively for illumination purposes. The scope of delivery includes the Blue-X-Focus light source and a power supply. The information in the operating instructions, in particular the safety instructions and permitted operating ranges, must be observed, and obey at every phase of the product’s life.
-15 °C to + 60°C, 5% to 95% humidity (non-condensing). Attach the lens cap to the Blue-X-Focus! The lens cap is used to protect the lens during transport and for long-term installation to protect the lens from dust and dirt.
Operation of Blue-X-Focus WARNING! Warning against melting of the lens cap and destruction of the Blue-X-Focus due to heat build-up. Always remove the lens cap before operating the Blue-X-Focus! The lens cap is primarily used to protect the lens during transport and for long-term installation to protect the lens from dust and dirt.
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-Focus • has to be checked by isi-sys for damages 1.6.
Technical description The Blue-X-Focus can be synchronized with a DAQ and can be triggered up to 100 kHz in pulse mode. The power of the LED is adjustable via a rotary knob on the back of the device. Besides it is equipped with a special active fan cooling and an integrated temperature safety switch-off.

Warning against melting of the lens cap and destruction of the Blue-X-Focus due to heat build-up. Always remove the lens cap before operating the Blue-X-Focus! The lens cap is primarily used to protect the lens during transport and for long-term installation to protect the lens from dust and dirt.
The Blue-X-Focus can be operated standalone in continuous wave mode when connected to the power supply through the power supply cable. To operate the Blue-X-Focus in pulse mode, the Blue- X-Focus must be connected to a trigger device (TTL Signal). The higher power of 220W can only be reached through pulse mode (depending on the duty cycle).

The DAQ is connected via USB with a Laptop or Desktop PC and is fully integrated in VIC Snap Data acquisition software. The BNC Trigger Input of the Blue-X-Focus is connected to Trigger I/O of DAQ with switch to “internal trigger”, optional the PFI13/ TTL can be used. In the “Timer Control”...
2.4. Focusing mechanism and Illumination area The Blue-X-Focus can be equipped with two different lens tubes. For larger field of view (FOV) we recommend using the focusing tube LFOV with the small knurled ring (left image). Depending on the flange focal distance the beam expands from 10° to 60°. For small areas the SFOV lens tube with the bigger knurled ring (right image) is recommended in combination with the diffus er, it expands from 7.5°...
Application examples for combination with DIC system (NO POLARIZATION FILTER ATTACHED!): → Scenario 1: Frame rate: 75 fps max. camera exposure time: 13.33 ms → max. Blue-X-Focus exposure time: 3.95 ms → Scenario 2: Frame rate: 35 fps max. camera exposure time: 28.5 ms →...
