Product Overview

Beam Imaging Solutions (BIS) introduces the new 90-degree BOS which allows remote imaging of a beam at 90 degrees to the imaging plane. Like the BOS-18-IW and BOS-40-IW, the new BOS-75-IW can be attached to a linear motion feedthrough and placed into and out of the beam allowing for remote imaging, deep within the vacuum chamber. The imaging is accomplished by mounting a standard BOS MCP/phosphor screen stack onto a metal housing which has a mirror mounted at 90-degrees with respect to the imaging plane. The housing is wedged shaped to minimize the physical size of the imager, and has convenient points for attaching to a linear motion feedthrough. Electrical connections are made by attaching flexible electrically insulated wires to a connection block on the wedge from an electrical feedthrough. In their standard form, the BOS-IW units are available with the MCP/phosphor assembly mounted to wedge shaped housing with electrical connection block. BOS-IW kits are also available, and include the BOS-IW unit with electrical feedthrough, viewport, linear motion feedthrough and camera systems. Contact us for more details.
