The board digitizes the output of an Optodyne Laser Doppler Displacement Meter and provides a 32-bit parallel target position in units of 1/256, or 1/128, or about 0.1 microinches (2.5 nanometers). The 32 bit position data may be read over the PC backplane and/or output to the machine tool and other positioning applications. Contains HeNe Tube, Optics a Photodetector Receiver, and electronics. ? Higher loop gain possible for closed loop servo control. ?

ER-400 Extended Range - Extends the range of the laser system to 400 inches. ER-2000 Extended Range - Extends the range of the laser system to 2,000 inches. LD-21RS Cable Set-Connects the Laser Head to the IPB Power Box. > The system configurations below provide information on selection of the proper board for your application. L-109N Narrow Beam Laser Head -Similar to the L-109, but designed to be used with flat mirror targets. The narrow beam heads used with flat mirrors allow simultaneous x-y measurement across flat mirror surfaces. Beam diameter is 0.5mm, and the beam divergence is 1 mrad....

Bit Plug-In Board - Automatic pressure and temperature compensation consists of an air pressure sensor, an air temperature sensor, and a material temperature sensor. This is a board that occupies an ISA bus halfsized slot in your PC. > In a two axis system (e.g. an X-Y stage) as shown in Figs. 1-1 and 1-2, the X-reflector can be allowed to move in the Y direction without affecting the signal strength of the X-measurement. Consequently, both reflectors in a 2-axis system can be mounted on the same moving part to minimize Abb offset error. Defining the measurement as the point where the axis beams...
