![]() The flexibility of our Cage Assembly System stems from well-defined mounting and thread standards designed to directly interface with a wide range of specialized products. Specialized cage plates that allow smaller optics to be directly inserted into our larger cage systems are also available. The 16 mm cage, 30 mm cage, and 60 mm cage standards are designed to accomodate Ø1/2", Ø1", and Ø2" optics, respectively. Thorlabs offers three standards defined by the center-to-center spacing of the cage assembly rods (see image below). 16 mm, 30 mm, and 60 mm Cage System Standards The Cage Assembly System provides a convenient way to construct large optomechanical systems with an established line of precision-machined building blocks designed for high flexibility and accurate alignment. These parts, along with SM1 Lens Tubes and 1" Post Assemblies, are sold separately. SM1 Lens Tubes and the SM1B3 Lens Tube Bellows (3) allow for a light-tight connection without inhibiting the free movement of the XYZ mount.Ĭomponents used in the configuration pictured below are listed in the table to the right. The SM1ZM zoom housing is mounted directly onto the ST1XY-D XY Translation Mount with Differential Adjusters (6), creating a compact XYZ mount. A lens (5) located inside the SM1ZM High-Precision Zoom Housing (4) focuses the beam onto a precision pinhole (7) located just before the avalanche photodetector's detector element. In the following example of a partial confocal microscope, a light-tight connection is created between a DFM1 Dichroic Filter Cube (denoted by 1 in the image below) containing a Microscopy Filter Set (2) and an APD130A( /M) Photodetector (8). Thorlabs' ST1XY-A, ST1XY-S, and ST1XY-D XY Translation Mounts are useful when precise alignment of optics is necessary. ST1XY XY Translation Mounts - Optic Alignment in a Confocal Microscope Detection Module The parts on this page are compatible with our 30 mm cage system and utilize Ø6 mm ER cage rods. In cases where coarse adjustment is sufficient, the SPT1C(/M) and SPT1CT(/M) Slip Plate Mounts provide ☑.0 mm of manual XY adjustment.Ĭage System Compatibility: Thorlabs offers 16 mm, 30 mm, and 60 mm cage systems designed primarily for Ø1/2", Ø1", and Ø2" optical components, respectively. Our ST1XY Translation Mounts offer up to ☓.0 mm of XY translation controlled by either 100 TPI adjuster screws, micrometer drives, or differential drives. For experimental setups requiring fine adjustment, consider using our CP1XY Flexure Adjustment Plate, CXY1A Cage Mount, or CXY1QA Cage Mount with Quick-Release Plate. SM05 (0.535"-40) or SM1 (1.035"-40) Threadingįor Ø1/2" or Ø1" optical components mounted in a 30 mm cage system, Thorlabs offers several options for XY adjustment (orthogonal to the mechanical axis of the cage system). ![]()
