XL laser controls and indicators
The front panel includes the shutter mechanism� The top panel includes
a laser status LED and five signal strength LEDs.
System overview
XL laser
The XL laser system is a modular system, capable of measuring
displacement, velocity, angular (pitch and yaw) displacement, flatness,
straightness, parallelism and squareness, depending on the measurement
kits supplied�
The XL laser is a single-
frequency HeNe laser�
It produces an extremely
stable laser beam, with a
wavelength that is traceable
back to national and
international standards�
XL-80Q quadrature laser
The XL-80 quadrature laser allows ‘raw’ interferometry signals to be
supplied to custom-designed circuitry� This allows the laser to be used
as a linear encoder system (not designed for closed loop feedback)�
The quadrature signals are accessed via the auxiliary I/O connector
on the XL laser rear panel. The option provides two levels of
user-selectable quadrature resolution – 80 nm and 10 nm

NOTE:
XL-80Q may be subject to export control restrictions in your region�
