NOTE
This product complies with the RoHS directive
(Restriction of Hazardous Substances) .
2.0 —Description
The DL linear stages Series is a high performance but very affordable,
inear motor driven with an integrated motion controller. Optimized for
l
mall loads, repeatable positioning and fast traverse speeds, it’s an ideal
s
olution for spectroscopy applications ranging from pump-probe,
s
interferometry, 2DIR, etc.
With travel ranges of 125 mm, 225 mm and 325 mm, this offering covers
almost all possible delay needs from femtosecond to nanosecond delays.
The DL stage utilizes an FEM-optimized extruded aluminum body that is
extremely stiff, while minimizing the bending effect caused by the different
thermal expansion coefficients of the aluminum body and the steel rails.
The rails' position relative to the profile’s neutral fiber minimizes the effect
due to bi-metal thermal expansion. The body's rigidity minimizes the
deflection under load.
The stage has been designed to be mounted on standard breadboards
(with a 0.2 mm flatness). This minimizes the effect of the table to pitch,
yaw and roll performance of the stage.
Recirculating ball bearing slides provide excellent payload capabilities and
long life. The movement is smooth with low noise.
Unlike screw driven stages, the DL employs a centered, high efficiency 3phase, synchronous ironless, linear motor as the driving element. This
drive system is absolutely non-contact, and has the advantage of higher
speed, high acceleration and high system responsiveness without wear
associated with motor brushes or drive screws. And because of the fully
integrated linear motor, the DL is shorter than a comparable screw driven
stage.
Precision position feedback is provided by a very repeatable linear scale
mounted in the stage. The encoder signals are interpolated by the
dedicated Newport motion controller with nanometer resolution for
outstanding position sensitivity, repeatability, and stability. A home
position is incorporated on the same scale, avoiding the use of additional
electronics or mechanics for improved reliability and accuracy.
Thus, the DL is the optimum solution for space constrained applications
that require high-throughput, high reliability, and ultra-quiet operation.
To facilitate setups, beam kits consisting of retroreflectors, mirrors,
mounts and other optomechanical parts, are available to suit various
wavelengths and delay line configurations.

DL Stage Series High-Performance Delay Line Stages
Specifications of our products are established in reference to ISO 230
standard part II “Determination of accuracy and repeatability of
positioning numerically controlled axes”.
T
his standard gives the definition of position uncertainty which depends
on the 3 following parameters:
Absolute Accuracy
Difference between ideal position and real position.
Accuracy
Difference between ideal position and real position after the compensation
of linear errors.
Linear errors include: cosine errors, inaccuracy of screw or linear scale
pitch, angular deviation at the measuring point (Abbe error) and thermal
expansion effects. All Newport motion electronics can compensate for
linear errors.
The relation between absolute accuracy and on-axis accuracy is as follows:
Ability of a system to achieve a commanded position over many attempts.
Reversal Value (Hysteresis)
Difference between actual position values obtained for a given target
position when approached from opposite directions.
Minimum Incremental Motion (MIM)
The smallest increment of motion a device is capable of delivering
consistently and reliably.
Resolution
The smallest increment that a motion device can theoretically move
and/or detect. Resolution is not achievable, whereas MIM, is the real
output of a motion system.
Yaw, Pi tch
Rotation of carriage around the Z axis (Yaw) or Y axis (Pitch), when it
moves.
The testing of accuracy, repeatability, and reversal error are made
systematically with test equipment in controlled environment (20±1°C).
A linear cycle with 21 data points on the travel and 4 cycles in each
direction gives a total of 164 points.
Guaranteed Specifications
Guaranteed maximum performance values are verified per Newport's A167
metrology test procedure. For more information, please consult the
metrology tutorial section in the Newport catalog or at www.newport.com

DL Stage Series High-Performance Delay Line Stages
3.5Dynamic Characteristics
Dynamic response of the stage depends on two parameters:
• The force delivered by the motor
• The total moving mass including carriage mass and payload
Newport’s DL Controller includes four parameters allowing dynamic
control optimization of the stage:
• Scaling Force
• Force Limit
• Carriage Mass
• Payload Mass
Although the three parameters are set in the factory perstage, the fourth
(Payload Mass) must be adjusted by the user. Refer to the “FM” command
of the Newport DL Controller user’s manual.
3.5.1Description of Parameters
The DL Controller/driver "ScalingForce" parameter is used by the
controller to scale the output current. It indicates the theoretical
maximum force (friction not taken in account) of the DL carriage with the
controller full scale current (See Controller Manual).
The DL Controller/driver "ForceLimit" parameter indicates the maximum
force of the DL stage carriage limited by current saturation to avoid stage
damage.
Then, stage carriage acceleration can be calculated using the following
formula:
MaxAccelaration =
Carriage Mass + Payload mass
ForceLimit - Friction Constant
See chapter 3.4.3 acceleration/Load graph.
• Due to its linear motor and rails, DL stage Friction Constant is only 4 N.
• Carriage Mass is 0.85 kg.
3.5.2Stages Adjustement Proposal in Function of the Load
In order to improve and have better driving performances, it is advisable
to change the control parameters according to the load. All the stages are
delivered with a crossover frequency of 70 Hz. You can change the
parameters KP, KI, KD, FD, FL and FMP in the controller terminal. Please
see the following table:

WARNING
Always turn the controller's power OFF before connecting to a stage.
Stages may be connected to the rear panel motor connectors any time
prior to power-up with the supplied cable assemblies.
NOTE
These stages are equipped with a chipset memorizing parameters.
Newport's exclusive technology enables Newport DL Controllers to
recognize the connected Newport stage. This ensures that the user can
operate the motion system quickly and safely.
5.2.1Newport cables
DL stages are delivered with two 3-meter pigtailed cables that can be
directly connected to Newport Controllers.
DL Series stages can only operate with cable lengths of 3 m max.
These cables are shielded. For correct operation, make sure to lock
connectors (ground continuity provided by cables).
Keep the cables at a safe distance from other electrical cables in your
environment to avoid potential cross talk.
