ST-3PH, ST-3PHB, ST-3PH-INCH-05, ST-3PHB-INCH-05 Post Holders

Aluminium Post Holders 3PH have a precise mounting opening for mounting posts 12 mm (Ø0,5’’ in imperial) in diameter. It provides two lines of contact, thus the position of a precision mounting post becomes definite. A mounting post is locked in position by a screw (included). The post holders 3PH can be mounted to other components using screws, or to breadboards and tables directly using adapters 3AH.

New Original Design of Post Holders 3PHB, which offers more usage convenience and flexibility. This solution was influenced by many requests for more compact optical schemes. Previous design is modified by introducing a slot, which allows clamping post holders to mounting surface using clamps like 3UTC, no additional parts required. Width of post holder with clamp does not exceed 25mm (1").

ST-3PC Post Clamps

Tool to secure mirror holders and other tools
on posts with:

Ø32 mm  -  ST-3PC-32

Ø25 mm  -  ST-3PC-25-01


Material: Aluminium

Finish: Black anodized

ST-3TPH-13 Translating Post Holder

Fine post height adjustment within 13 mm without rotation

One rotation of adjustment ring adjusts height of post by 1 mm

High stability position locking

Material: Aluminium

Weight - 0.15 kg

Translation Post Holder 3TPH-13 is used for height adjustment of components mounted on 12 mm posts 3MP or equivalent. Range of coarse height setting is 50 mm. After coarsely setting position, post is locked inside the 12 mm round bore with stable two-line contact using upper thumbscrew with hex socket. Precise height adjustment is then done by a handy knurled adjustment ring. One rotation of the ring moves the post up or down 1 mm to a total of 13 mm. Precise position can be locked using the lower thumbscrew.

M6 threaded hole in the base can be used for attaching directly to optical table, to other positioners or to magnetic bases 3CMB.

ST- EXC45 Rotary Clamp

The Rotary Clamp is used to fasten components at random positions where they cannot be fastened directly to the optical table. Screw a post or post holder onto the clamp's knob. Then locate the component at the required position. While the knob is firmly attached to the component, it allows the plate to rotate freely. Position the plate's slot over a tapped hole and screw it down to clutch the knob. The component will remain stable.


Material: steel with chemical black finish.

Weight: 0.08 kg

ST-3TC5 Table Clamp

Using Table Clamps 3TC5 you can position any Standa base, available through Laser Support Services, and most base mounted components at any angle on the table and have not to be limited by mounting hole pattern of the optical table. For using clamps the device is positioned so the slot of the clamp is over the base and so the screw can be inserted into a tapped hole. Tightening this screw can generate sufficient force for most mounting applications.

ST-3TC6/ST-3TC7 Table Clamps

Using these Table Clamps you can position any Standa base, available through Laser Support Services and most base mounted components at any angle on the table and have not to be limited by mounting hole pattern of the optical table. For using clamps the device is positioned so the slot of the clamp is over the base and so the screw can be inserted into a tapped hole. Tightening this screw can generate sufficient force for most mounting applications. 
Weight: 0.03 kg

ST-3RPC Right Angle Fixed Post Clamp

The base plates are made of black anodized aluminium and are available in different dimensions for use with mounts for specific components.

ST-3RPB Round Base Plates

Round Base Plates are used for mounting posts and posts holders to position them at random. The post stays stable without fastening. If required, the plate can be fastened using specific Table Clamps.
Material: black finished steel, or black anodized aluminium

ST-3EXP59 Base Plates with Eccentric Clamp

These base plates are used to clamp posts and post holders in random positions. Attach a post to the base using an M6 screw. Set the position. The base rotates around the clamp through 360° and translates within 10 mm. Fix the clamp with an screw. The base is of black anodized aluminium.

Riser Blocks


ST-3RB135 Riser Blocks

Riser Blocks are designed to use with appropriate base plates to elevate the optical axis of mirror and lens mounts. Also another component mounts are assembled to base plate through the Riser Blocks using M4 socket-thread cap screw. The Riser Blocks are made from black anodized aluminium and have a lip on the edge for aligning it with the base and for prevention of its rotation.

ST-3URB111 Universal Riser Blocks

Universal Riser Blocks are the combination of the Riser Block and the Base Plate. They allow all components to be mounted at fixed axis height 10 mm using ST-3URB111-01(03) or 20 mm using ST-3URB111-02(04). The Universal Riser Blocks are made from black anodized aluminium.
