• Wide Range of Carrier Length and Mounting Hole Options Available
• Low Profile Design with Smooth Movement
• Increased Stability and <1 mrad Straight Line Accuracy
Dovetail Optical Rail Systems are designed for easy and stable installation and positioning of various optical
components along the same axis. The rails feature slotted holes that allow them to be fixed to standard ¼-20
TPI and M6 breadboards or optical tables. Carriers are available with different lengths and hole patterns to meet
various mounting needs including options that are directly compatible with our TECHSPEC® Manual Stages for
precision alignment. Carriers utilize a unique two-piece design to prevent the locking screws from contacting the
rail and to allow easy attachment and removal. All Dovetail Optical Rail System parts are constructed of black
anodized aluminum to minimize stray reflections or glare. Note: Rails and carriers are sold separately.

• Rails and Carriers Available
• Mount on English and Metric Breadboards
• Low Profile Design
Compact Optical Rail Systems are designed to easily mount and position optical components, and to provide a defined
optical axis with a straightness within 1 mm over 1m. Rails feature slots that allow M6 or ¼-20 socket head cap screws
to lock the rail to breadboards or optical tables. Carriers feature mounting holes for metric posts and post holders,
and utilize thumbscrews to lock the carrier to a rail. Rails and carriers are constructed of black anodized aluminum to
decrease glare or stray reflections. Compact Optical Rail Systems are ideal for compact benchtop applications. Compact
Optical Rail Systems are ideal for compact benchtop applications. Note: Rails and carriers are sold separately.
