Thorlabs offers a wide variety of optical breadboards in different sizes and shapes, including solid aluminum breadboards and honeycomb breadboards. The surface of the optical table and the optical breadboard may or may not have threaded mounting holes. In addition, Thorlabs also provides breadboard support racks, enclosure systems, and other optical platforms and optical breadboard accessories. Thorlabs' breadboards include 1/4 inch-20, M6, # 4-40 or M3 threaded holes. 1. Solid aluminum breadboard Thorlabs offers different sizes of non-magnetic aluminum breadboards with threaded holes in both metric and imperial. These breadboards cover standard series, ultra-thin type with double-density holes, Mini series, large-area mobile table, large-area rotating table and water-cooled breadboard. 1a. Standard series The solid aluminum bottom plate provides an economical and convenient platform for the formation of optical element prototypes, conduction experiments, and installation of small subsystems. The breadboard is anodized to black to minimize surface reflections, and has standard 1 inch (inch) or 25 mm (metric) through holes, which are 1/2 inch or 12.5 mm from the edge of the breadboard, respectively. Figure 1 MB1015 / M-M6 threaded aluminum breadboard 1b. Ultra-thin type with double density holes This solid aluminum elongated breadboard is made of a 1 / 2-inch (12.7 mm) thick aluminum flat plate that maintains flatness throughout its length and provides double-density 1 / 2-inch (12.5 mm) holes Layout. This narrow and long structure is suitable for compact areas and increases the diversity of installation by doubling the number of threaded holes on the mounting surface. Since these threaded holes penetrate the entire bottom plate, the components can be installed on both sides of the breadboard. The breadboard can be mounted on the optical platform through a post with a support, allowing the components on both sides of the breadboard to be operated. Figure 2MB424-Double density holes, 1 / 4-20 thread aluminum breadboard Figure 3 MB1060 / M-Double density holes, M6 thread aluminum breadboard 1c.Mini series Mini series breadboards have 4-40 (M3) threaded holes with a center distance of 1/2 inch (12.5 mm), which greatly increases the number of optical components that can be assembled in a limited space. Four countersunk through holes have been repositioned. On the inch optical breadboard, each hole is located 1 inch x 1 inch from the edge. On the metric optical breadboard, each hole is located 25 mm x 25 mm from the edge. This allows the optical breadboard to be installed on any of Thorlabs ’standard breadboards. Figure 4MS12B-High-density Mini breadboard 1d. Water-cooled breadboard This breadboard consists of MB series breadboards with water cooling system. They have standard 1-inch or 25-mm holes and are suitable for sensors, detectors, lasers, LEDs, and other instruments that require temperature stability. The breadboard can be cooled or heated as required. Figure 5MBC3030 / M-Water-cooled breadboard with M6 threaded holes 1e. Large area mobile platform Designed for experiments with complex systems that require adjustable positions. Rough positioning can be performed by pushing the mobile platform. Use the hex wrench to adjust the frame and gear to achieve fine positioning within the full stroke. Figure 6TBB0606-Large area mobile platform 1f. Large area rotating platform Thorlabs' large-area rotating platform is designed for applications where certain optical components require angle adjustment. There is a Ø3.84 inch (Ø97.5 mm) removable wafer in the middle of the breadboard, which is convenient for placing other components in the middle. At this time, the breadboard rotates around the central component. The platform is characterized by a three-point adjustable installation system, using dovetail positioning to achieve accurate position adjustment; one of the installation positions uses spur gear adjustment, and the other two installation positions use locking screws. The mounting position near the rotating turntable has slots to fix the breadboard to a standard optical platform or breadboard; the position of these slots can be adjusted to avoid equipment installed nearby. Figure 7RBB12-Ø12 inch rotating breadboard 2. Honeycomb Breadboard Thorlabs' honeycomb breadboard product line includes the Performance and PerformancePlus series. The Performance series breadboard combines a double-layer board (top and bottom) and a single honeycomb design, with excellent rigidity and dynamic rigidity, can provide high rigidity and standard damping, is a popular OEM breadboard. PerformancePlus series has vibration isolation performance, adopts three-layer board structure, internal honeycomb structure and internal damping mechanism. 2a.Performance series high rigidity, standard damping breadboard Performance series breadboard adopts adiabatic design to provide excellent thermal stability, steel honeycomb core and internal damping structure provide static and dynamic rigidity, and use the most advanced materials and thermal bonding treatment, with excellent surface smoothness. Figure 8 Performance series breadboard (the picture below is a non-porous breadboard) The PerformancePlus optical breadboard is specifically designed for demanding R & D applications. It has all the characteristics of a Performance breadboard, as well as enhanced damping, increased rigidity, and sealed mounting holes. Its enhanced damping design improves dynamic performance and is suitable for the most stringent laboratory applications. Figure 9 PerformancePlus breadboard 2c. UltraLight series high rigidity breadboard Thorlabs UltraLight series breadboards use high-density cores and internal damping, with high static and dynamic stiffness. Matte surface treatment reduces reflectivity and backscatter. In addition, this series of breadboards provide high strength to weight ratio and excellent thermal stability. These breadboards are ideal for optical systems that require high portability and dynamic rigidity. Figure 10 UltraLight Series I Breadboard Figure 11 UltraLight Series II Breadboard 2e. Non-magnetic breadboard Thorlabs non-magnetic optical breadboards are suitable for applications where the magnetic fields generated by equipment or experiments may be disturbed by ferrous desktops. The breadboard is a double flat plate single honeycomb structure, using a non-magnetic 304L stainless steel top plate and bottom plate. The aluminum honeycomb core and internal damping provide static and dynamic rigidity to minimize deflection under load. The use of thermally matched materials achieves excellent surface smoothness. Figure 12 Non-magnetic breadboard In addition, Thorlabs can customize breadboards to meet specific needs according to user requirements.
