- Page 5 IR Viewers Chapter 1: Safety Chapter 1 Safety Shock Warning Electrical safety requirements must be followed while operating this device. Warning The customer is responsible for light source safety while using viewer as a standalone device or integrated into a system.
- Page 6 Chapter 2 Description About Infrared (IR) viewers (Item #’s VWR1B and VWR2B) are high-grade image converters designed to observe indirect radiation of infrared lasers, light emitting diodes (LED), and other IR sources in the 350 – 1700 nm region. The lightweight, compact device is designed to be used hand-held.
- Page 7 Figure 1 Diagram of the IR Viewer Phosphor Screen Parts List Each of the VWR1B and VWR2B IR Viewers will come with the following parts: 1. The VWR1B or VWR2B IR Viewer 2. One Cap for Removable Filter 3.
- Page 8 IR Viewers Chapter 3: Operation Chapter 3 Operation Caution Do not use the device for direct beam viewing. Long-term over-exposure may cause saturation of screen and decrease of resolution or irreversible reduction of photocathode response. Warning While operating the viewer, do not stare at the direct laser (or other source) light even with safety goggles.
