1. Introduction The EQ-400 Laser-Driven Light Source (LDLS®) is a broad-band lamp system for use in a wide variety of applications. The lamp produces high brightness, broad-band light from deep ultraviolet (UV) wavelengths through visible and beyond. The output is very stable and has a long lifetime before any service is required. A simple control interface ensures ease of use.
CAUTION: The EQ-400 emits dangerous levels of UV radiation. Even short exposures to skin or eyes may cause burns. Ensure that only authorized personnel are in the vicinity of source during operation. Personnel in vicinity of operating source should wear protective eyewear, clothing, and gloves.
2.3. Laser Information The EQ-400 uses a patented* laser drive system to excite a plasma that radiates in the ultraviolet as well as the visible bands. A Class 4 laser is located in the Controller enclosure. The optical configuration of the Lamp ensures that the direct laser beam cannot exit the unit.
2.4. Labels and Safety Notification Table 1 shows the location of The following safety labels appear on the product. each label on the EQ-400 system and Table 1 describes their meanings. Figure 1: EQ-400 Safety labels location...

Lamp Control Connector Provides various power and control signals to/from the Lamp module. No other connector (9-pin D-sub) or cable may be used with the EQ-400 other than the one supplied.
addition to the light output, invisible laser radiation exceeding Class 1 emission limits is emitted from the output aperture. Laser collimator Device that narrows the beam of light Figure 5: EQ-400 Lamp back view EQ-400 Lamp – Back view Component Description Nitrogen Purge These are the fittings for the required nitrogen purge gas.
Connect the laser fiber to the Lamp as follows: WARNING: The collimator must never be detached from its mounting bracket. Doing so could allow dangerous invisible laser radiation to be emitted a. Remove plastic cap from the end of the laser collimator Note: always keep this cap in place when the laser fiber is not connected to the Lamp.
5. EQ-400 Operation 5.1. Startup Once the lamp is set up properly, verify that all personnel that will be in contact with the lamp system are aware of the potential hazards involved. It is the responsibility of the user to verify that the lamp is being used safely and to consult their laser safety officer for safety measures specific to their use of the source.
If there is a component failure, do not attempt to open the Controller or Lamp enclosure of the EQ- 400. Any service to the system must be performed only by factory authorized and trained technicians. To avoid injury, under no circumstances should the user open or modify the Lamp or Controller enclosure. 7.
8. Accessories The EQ-400 requires a chiller to maintain the cooling requirements in Section 3.4. For your convenience Energetiq offers a suitable chiller produced by SMC Corporation. You may also choose to procure a chiller directly through your local SMC Corporation representative (SMC PN HRS018-A-10-T). Description EQ-400-CHILLER-KIT EQ-400 Chiller / with Tubing Kit...

full scale power. Laser power can be increased or decreased in increments of 0.5%, from 40% to 100% of full scale. The interface also allows monitoring of system status. Commands consist of a single ASCII character, case-sensitive. This can be transmitted to the EQ-400 via a terminal emulation program, or the user's control system.
