Device

Specications

The 2D contour maps and the 3D isometric plots can be

displayed with or without scan axis and grids, and the

isometric plots can be rotated for easier viewing of the

detailed structure.

BeamMaster System Components

Each BeamMaster system consists of a sensor head, complete

with a 1.8 m cable, a 1/2-length (187 mm) 32-bit PCI card to

plug into a PC computer, complete Windows software on a

CD-ROM disk, a printed instruction manual, a 0.5” mounting

post (threaded 8-32), and optical lters (for Si-Enhanced).

Optical Filters

The BM-7 and BM-3 Si-Enhanced heads come with two

neutral density lters. NG4 and NG9 lters (complete with

transmission curves) are provided to extend the power range

of the heads from 5 mW to 1W in the 400 nm to 1100 nm

range. The NG4 lter comes pre-installed and provides ~10%

transmission at 633 nm. The NG9 lter is in a protective lter

case and provides ~0.5% transmission at 633 nm. There is no

lter in the BeamMaster InGaAs head congurations.

Computer Requirements

The user provides a Pentium PC (586 or higher, 233 MHz)

operating Windows 2000 or XP with a free PCI card slot. The

system should have 32 megabytes of RAM, a CD-ROM drive,

~20 megabytes of free hard-disk memory, and a display

resolution of 800 x 600 or higher.

BeamMaster Accessories

An optional mount is available to enable rotation of the

BeamMaster sensor head about the optical axis. This mount

has a 360-degree calibrated scale with a locking screw. An

optional C-Mount Adapter Plate allows the attachment of any

C-Mount, threaded optical accessory, such as a BCUBE high-

power attenuator pickoff optic (see the Beam Diagnostics

Accessories section on page 68).
