Illumination optics contains a fiber optic light guide. This provides versatility for different illumination requirements. A focusing lens is installed to the end of the light guide for the generation of uniform illumination. Cavitar can also provide other illumination solutions such as back illumination or line illumination (see Chapter 6). - Page 16 TRIG IN connector of the control unit. Two TRIG IN connectors are available: an optical trigger provided by Cavitar shall be connected to the D9 connector o other trigger signals shall be connected to the BNC connector, allowed signal: TTL, 0…+5 V (input impedance approx.
- Page 17 NOTE! • To enable laser operation, the terminals of the Remote Interlock (RIL) connector (LEMO EPG.0B.302.HLN socket) need to be short-circuited together (do not connect to ground!). To disable operation, disconnect the terminals from each other. The device will not emit laser radiation when the terminals of the RIL connector are open-circuited (IEC/EN 60825-1).

5 Operation After successful installation CAVILUX Smart is ready for operation. In the following the operation of the system is described in more detail. 5.1 Preliminary issues Before operation the following preliminary issues need to be performed: • check that laser unit, illumination optics and control unit are installed appropriately and that all optical surfaces are clean •... -

5.2.1 General The front panel of the CAVILUX Control program is presented in Figs. 5.1 (Normal Mode) nd 5.2 (High Speed Mode). The software version in the figures contains eight output hannels, but the number of output channels can be e.g. two. Fig. -

60 s cooling period will take place. It is possible to operate CAVILUX Smart at very high duty cycle (up to 90 %) for very short time (max. total laser active time 10 μs). Please see Section 5.4.5 for more details. -
Page 21: Programming Pulse Patterns
5.2.3 Programming pulse patterns CAVILUX Control program can be used to create new pulse patterns and to load or modify existing pulse patterns. The programming of a new pulse pattern begins by selecting File New. The pulse patterns are programmed in the ”Pulse Pattern” block. Odd channels are for cameras (Cam) and even channels for laser units (Laser). -
Page 22: Trigger Settings
5.2.4 Trigger settings After the pulse patterns have been programmed, it is time to choose trigger settings. CAVILUX Smart contains versatile trigger properties, which are described in more detail below. Trigger settings are set in the ”Trigger” block (cf. Fig. 5.1). -
Page 23: Power Settings
NOTE! • Max. repetition rate depends on the laser active time. When using external triggering, the control unit will ignore those trigger signals that appear at higher frequencies than allowed. For example, if the maximum repetition rate is 1 kHz, there has to be at least 1 ms duration between successive trigger signals. - Page 24 After the “Set” button has been pressed, the outputs can be activated by either: • clicking the ”Start” button in CAVILUX Control software (requires USB2 connection!), • pressing the Start/Stop button in the front panel of the control unit, or •...

All spot sizes are approximate values. Table 5.1. Spot sizes at different working distances. Fiber core Ø... -
Page 27: Maximum Repetition Rates For Different Pulse Durations
Note: With shortest pulse durations the actual pulse energy is lower due to rise and fall times. 5.4.4 Dependence of wavelength on temperature The output wavelength of CAVILUX Smart depends on temperature. Typically the output wavelength increases with increasing temperature by approximately 0,3 nm/°C. CAVILUX Smart has been characterized in normal room temperature (~20 °C). -
Page 28: Ultra High Speed Operation
In some applications there may be need for using the system at very high duty cycle for a short time. For this reason it is possible to use CAVILUX Smart at max. 90 % duty cycle provided that the total laser active time is max. 10 μs. For example, one can generate 10 pulses of 1 μs duration at max. - Page 29 o find out the optimal laser/camera delay by adjusting the respective delays in CAVILUX Control software (first “0” row in laser/camera channel, see Sections 5.2.3 and 5.2.7) o an optimal delay is found when: the image is bright and stable AND reducing the laser delay (or increasing the camera delay) by even a small amount makes the image darker and/or unstable (this ensures that the laser pulse is fired at the beginning of the camera exposure)

(front illumination, side illumination, back illumination, mirror reflection, almost mirror reflection …) o note: the light output of CAVILUX Smart is essentially plane-polarized. The effect of polarization in the images can be checked by rotating the laser unit around the optical fiber (rotating the fiber doesn’t have any effect) - Page 31 a) check that all system components seem to be intact pay special attention to cables and connectors check the condition of the protective window of the illumination optics b) check that the fiber-optic light guide is intact if the fiber is broken or if the input or output end is dirty or damaged, the fiber will not transmit light properly.

Page 32: Maintenance And Service Information
6 Maintenance and service information CAVILUX Smart is essentially maintenance and service free so normally there is no need for these operations. However, sometimes there may be need to clean optical surfaces or casings or to replace the protective window of illumination optics. -
