These vacuum-compatible versions of the AB90, AB90H, AB90A(/M), and AB90C(/M) brackets above are chemically cleaned and prepared for vacuum applications before packaging. They are compatible directly out of the packaging with vacuum environments down to 10-6 Torr. With additional cleaning and processing, they can be used at even lower pressures, only limited by the outgassing rate of the aluminum. The material properties of the aluminum and the cleaning methods completed by the end user should be used to determine the appropriateness of these products and materials in a specific vacuum system.

The photo to the right shows the TS240 with two KM100 Kinematic Mounts, two ME1-P01 Protected Silver Mirrors, and two BA2 Bases. One BA2(/M) base is included with the tombstone mounting block; mounts and mirrors are sold separately.

Our AP90L(/M) Large Right-Angle Plate is a heavy-duty mount, capable of holding breadboards at 90° relative to an optical table's surface. This plate provides a generous array of 31 1/4"-20 (M6) tapped holes and six 1/4"-20 (M6) counterbores oriented at 90° from the optical table surface. Its base contains three 1/4"-20 (M6) clearance slots and six 1/4"-20 (M6) counterbored holes for mounting to an optical table.

For an alternative 90° mounting option, the top plate on our AP180 Adjustable Angle Plate can be positioned to provide mounting configurations similar to the AP90. Thorlabs also offers 45° and 30°/60° mounting plates.

Thorlabs' Smart Pack Initiative is aimed at minimizing waste while providing adequate protection for our products. By eliminating any unnecessary packaging, implementing design changes, and utilizing eco-friendly materials, this initiative seeks to reduce the environmental impact of our product packaging. The updated TS240 and TS240/M packaging consists of recycled cardboard and weighs 6.7% and 14.7% less, respectively, than the original packaging. This weight change results in a respective 0.86 kg and 1.85 kg reduction in travel-based CO2 emissions per year, based on typical product sales. The other products on this page have transitioned, or are in the process of transitioning to recycled paper packaging.As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen above.

Shown to the right are a standard cap screw and a low-profile channel screw installed in an RM1G cube. The low-profile screw's shortened cap height prevents neighboring screws from interfering with each other.

Our MSAP90(/M) Mini-Series Right-Angle Plate, based upon our popular AP90 Right-Angle Plate design, is an ideal solution for constructing rigid three-dimensional assemblies with our Mini-Series components. This bracket provides four 4-40 (M3) clearance slots, seven 4-40 (M3) tapped holes, and two 4-40 (M3) counterbores oriented at 90° from an optical table surface. Its base contains two 1.0" (25.4 mm) long, 4-40 (M3) clearance slots and two 4-40 (M3) counterbores for mounting to a Mini-Series Breadboard.

These right-angle brackets can be used to fasten optical construction rails to each other or to an optical table. Each bracket can be secured to an optical rail by screwing it to T-nuts (not included) inserted into the rail channels. Either the XE50A90 or the XE75A90 bracket may be used with our 50 mm x 75 mm rails, depending on which side of the rail(s) the bracket is attached to.

Our Low-Profile Channel Screws have a reduced cap head height relative to standard screws, permitting them to be used in tight spaces. In particular, they are recommended when neighboring screws are at a right angle and in close proximity, as in our XE25W3 Corner Cube or RM1G and RM1S Construction Cubes.

These Construction Cubes contain three 1/4" (M6) counterbores on adjacent faces. They can be connected to up to three optomechanical components by tightening our Low-Profile Channel Screws (sold below) through the counterbores, as shown in the images to the right. In addition, the RM1S cube has slotted corners to accept posterboard and hardboard walls for the construction of light-tight optical enclosures. Since both these cubes are machined from a single block of aluminum, they are ideal for constructions that need to be as sturdy as possible.

Thorlabs' Right-Angle Mounting Adapters assist in creating sturdy three-dimensional optomechanical assemblies and are suited for setups of virtually any size. They can be used directly with mounted optomechanics or as supports for larger structures. The parts shown below are either machined from a single block of aluminum or constructed from extruded lengths of aluminum for exceptional precision and rigidity. We also offer vacuum-compatible versions of our general-purpose Right-Angle Brackets for 1/4"-20 (M6) Cap Screws.

These construction cubes have one centered tapped hole on each of their sides. Machined from a single block of aluminum, they are ideal for constructions that need a high degree of sturdiness. By using setscrews, up to six optomechanics can be attached to each cube.

Thorlabs also offers a variety of other vacuum-compatible optomechanical components and breadboards that can be combined to build experimental setups for use within a vacuum chamber.

The AP90(/M) Right-Angle Plate is an ideal solution for building sturdy three-dimensional optomechanical assemblies that require vertical positioning. This plate provides four 1/4"-20 (M6) clearance slots, seven 1/4"-20 (M6) tapped holes, and two 1/4"-20 (M6) counterbores oriented at 90° from the optical table surface. Its base contains two 1.30" (34 mm) long, 1/4"-20 (M6) clearance slots and two 1/4"-20 (M6) counterbores for mounting to an optical table.

These Vertical Brackets are designed to mount any of our aluminum breadboards vertically on an optical table. The edges contain 1/4" (M6) clearance holes and 1/4"-20 (M6) tapped holes at regular spacings, providing a high degree of mounting flexibility. The VB01A(/M) has three 1/4"-20 (M6) tapped holes along the 45° edge for additional mounting options. 6", 11.75", and 18" tall brackets are available.

Thorlabs also manufactures an Adjustable Mounting Plate and Right-Angle Clear Aperture Brackets for other applications requiring vertical mounting, as well as 30°, 45°, and 60° angled mounting plates. For mounting two posts at a right angle we offer Ø1/2" Post Angle Mounting Clamps and Ø1" Post 90° Mounting Clamps.

The LCC1111-D from Thorlabs Inc is a Waveplate with Wavelength Range 1650 to 3000 nm, Waveplate Thickness 8.0 mm (0.32"), Waveplate Diameter(Inch) 1 Inch, Waveplate Diameter(mm) 25.4 mm. More details for LCC1111-D can be seen below.

If compatibility with more than three optomechanical components is needed, or if components are to be placed on opposing faces, please consider the RM1F Construction Cube below.

The AP90RL(/M) Large Angle Bracket is a heavy-duty component ideal for mounting breadboards and other bulky optomechanics at right angles to an optical table. The front, sides, and top contain a generous array of 1/4"-20 (M6) tapped holes and clearance holes, and the front additionally provides two parallel 2.40" (61 mm) long clearance slots. The base contains two 1/4"-20 (M6) clearance slots and five clearance holes, as well as two arched 1/4"-20 (M6) slots that provide continuous rotation of ±50° prior to fastening the bracket down.

By offering a total of 160 1/4"-20 (M6) and 8-32 (M4) tapped holes, the TS240(/M) Tombstone Mounting Block provides unparalleled vertical mounting capability. All five exposed surfaces provide a generous array of tapped holes for compatibility with virtually all standard optomechanics.
