Chapter 1. Introduction Chapter 1. Introduction The EQ-77X Laser-Driven Light Source (LDLS®) is a broadband lamp system for use in a wide variety of applications. The lamp produces high brightness, broadband light from DUV 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. ...
Chapter 2. Safety and Compliance Chapter 2. Safety and Compliance 2.1 General Precautions The output beam from the EQ-77X should be blocked when not in use with an electronic shutter or other appropriate beam blocking device. Due to the possibility of generating ozone with some models of EQ-77X when ambient oxygen is exposed to short wavelength light, the beam should always be enclosed in an appropriate beam pipe, tube, or enclosed space.
Chapter 2. Safety and Compliance WARNING: The EQ-77X utilizes an internal Class 4 IR laser capable of causing severe injury to eyes or skin. Do not open or attempt to service this unit. Contact Energetiq regarding any problems with the unit. WARNING: When working near the emitted light, always wear protective devices (conforming to ISO ...
Chapter 2. Safety and Compliance CAUTION: controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. WARNING: Invisible laser radiation avoid eye or skin exposure to direct or scattered radiation Class 1 laser product. Alternating current The EQ-77X is a Class 1 Laser Product. All appropriate laser safety measures should be in place before operating the system.
