    C h a p t e r 1 GENERAL INFORMATION Safety WARNING This unit emits ultraviolet (UV) radiation that is harmful to humans. Avoid exposure to the direct or reflected output beam. Make certain that the appropriate output beam shields and optics are in place prior to energizing the unit.
  • Page 8 Do not open or attempt to service this unit. Contact Energetiq regarding any problems with the unit. General Precautions The output beam from the EQ-1500 should be blocked when not in use with an electronic shutter or other appropriate beam blocking device.
  • Page 9 There are no user-serviceable parts inside the EQ-1500. For any problems encountered during operation, please refer to the Troubleshooting section of this user manual. If there is a component failure, do not attempt to open the chassis of the EQ-1500. The EQ-1500 utilizes a quartz lamp containing a high-pressure gas fill.
  • Page 10 The unit must not be operated if the covers are removed or it is defective in any way. Contact Energetiq if any problems with the equipment are suspected. Labels and Safety Notification The following safety labels appear on the product.

  • Page 13 The interlock circuit must be connected to enable the operation of the unit. Should the interlock connection open during operation or standby, the source is immediately disabled, and all light output from the aperture ceases. The source is then latched off and will not restart until the interlock is restored and the lamp manually restarted.

    C h a p t e r 2 DESCRIPTION General The EQ-1500 is a DUV lamp system for a wide variety of applications. The lamp features high brightness, broad-band light from DUV wavelengths through visible and beyond. The output is very stable, and has a long lifetime before any service is required. The interface is quite simple, but robust enough for any lab or industrial environment.

Minimum bend radius for the cable is 30 mm (1.2 in). See instructions in Chapter 3 under “Installation Procedure” for details on inspecting, cleaning and installing the fiber.

    C h a p t e r 3 INSTALLATION Installation of the EQ-1500 consists of connecting electrical, water, and gas supplies, and connecting the lamp output to the user’s equipment. Unpacking Upon arrival, start by inspecting all parts of the system for completeness and any damage incurred in shipping.
  • Page 26 Cooling Water The EQ-1500 requires 1.9–3.8 lpm (0.5–1 gpm) water at a minimum of 0.14 MPa (20 psi). The temperature must be held at 22 ± 1 degrees C. The pressure drop at 3.8 lpm (1 gpm) through the cold plate is less than 0.07 MPa (10 psi). There are several thermoelectric and direct water-to-water chillers that can satisfy these requirements.
  • Page 27 So first and foremost, the nitrogen purge gas is intended to displace any oxygen in the system’s optical chamber. The optics assembly is in direct contact with this purge gas. UV optics are quite prone to UV photo contamination. Clean and pure nitrogen from either a dewar or research-grade N bottle is recommended.

  • Page 29: Installation Procedure

    Operating the source without any output target or beam transport is not recommended, and may lead to unsafe operating conditions. Consult Energetiq for applications information and suggested configurations. 3. Set up the Lamp House with appropriate ultraviolet safety measures and laser light safety measures in place.
  • Page 30 Fiber installation procedure Step Picture Description 8.1. Using the supplied 1/16” hex driver, remove the screws securing the lamp house cover. Carefully lift the cover straight up. 8.2. CAUTION: The shielded fiber located on the back of the controller has a minimum bend radius of 30mm. Use care not to bend the fiber too tightly.
  • Page 31 8.4a While supporting the end of the fiber, place the strain relief against the side of the lamp house. You will see two ‘fingers’ that lock the strain relief in place from the back side. These will need to slide over the inside surface of the panel.
  • Page 32 Again, use extreme care not to touch the end of the fiber. Carefully slide the fiber into the SMA connector and tighten finger tight. Using care not to pinch any wires, slide the lamp house cover back into place and install the cover screws. The fiber installation is now complete.

    C h a p t e r 4 OPERATION 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 with its operation. It is the responsibility of the user to verify that the lamp is being used safely.

    Stopping To shut off the lamp, push the Operation Selector Switch down momentarily to the OFF/RESET position. The lamp can also be shut off by shutting off the main power switch on the rear panel. Opening the interlock chain will also stop the lamp, and the EXTERNAL INTLK OK indicator will go out.
