Precision Crystal Angular Positioning Stage
                                               --ultra stable, ultra compact, ultra economical!

In response to the demand of precise and flexible angular positioning of nonlinear optical crystals, U-Oplaz now introduces the high precision -- RS Series Rotation Stages. During angular critical phase matching process, wide range, very accurate and repetitive angular positioning has to be realized in order to scan the wavelengths over a very wide range and repeat the optimium power at the same time.  RS Series stages are designed to provide the highest possible degree of angular precision for such applications. With ultra stable design, these rotation stages provides backlash free rotation over a typical angle range of 60 degrees with a resolution down to mrad --- only limited by the resolution of the micrometer drive. At the same time, there is almost no wobble movement in the other direction.  They could be used in either vertially or horizontally, be positioned at any angle and position. They are compact, only half the size of other rotation stages with comparable resolutions --- making tight arrangement of 2 rotation stages possible. For delay lines and other general linear motion, we offer a precision motorized linear stage UP-XYZ.

Along with the 3 RS Rotation Stages, you can choose our high performance, yet very economical Dynaposition Motion Control System for fully automatic synchronized scanning. Also, you can choose a variety of  Fine Positioning Micrometers to control the RS series rotation stages.  When you use RS series rotation stages to position NLO crystals, you can use our specially designed Crystal Mount for NLO crystals which are required to be tuned over a very large angle range.

Features and Specifications:

• Backlash free
• Wobble free
• Economical (starting at $188)
• Ultra-compact, half the size of comparable precise stages

2. Specifications (nominal for RS-1 single axis stage)

3 models with customized design

The RS series rotation stages comes in 3 models.
RS-1
  
RS-1 is a single axis rotation mount. The stage comes with complete mounting holes so that you can use the mount both vertically and horizontally. You can also mount the stage on many standard mechanical parts, which offers you infinite flexibility.

The stage top is a 1" high stadard post holder, on top of which you can install a variety of optics that requires precise rotation.

Applications: Precision angular positioning of optics and crystals.
Order Information: RS-1-Mic, (check the choice  of micrometers to fill the "Mic" option)
 

RS-1L2

(a RS-1L2 controlled by an 850F acuator.)
RS-1L2 is a dual axes rotation stage, and the two axes are linked without play to form a counter rotation mechanism.
It is controlled by a single micrometer.
Separation of the two axis: 3.00"
Applications: compensation of optical displacement, walk-off in birefregent crystals.
Order Information: RS-1L2-Mic, (check the choice  of micrometers to fill the "Mic" option)

RS-2

(shown is a RS-2 with 2 Crystal Mounts for High Power Lasers)
RS-2 is a dual axes rotation stage, and the two axes are closely positioned so as to have a space saving design. The stage is controlled with 2 independent micrometers. It could also be mounted horizontally and vertically.
Standard separation of the two axis: 2.00", customized version could be down to 0.75".
Application: space saving design of precise angular positioning of multiple axes.
Order Information: RS-2-Mic1-Mic2, (check the choice  of micrometers to fill the two axes "Mic" options)
