FiberBench Alignment Tools![]()
HWXYT-C Beam Displacement Module AP1.5 Ø1.5 mm Aperture Plate VRC2D05 IR Alignment Disk AP1.5 Mounted on a FiberBench ![]() Please Wait Thorlabs offers alignment tools designed for our FiberBench systems, including XY Tweaker Modules, Aperture Plates, and IR Alignment Disks. The XY tweaker modules allow for the compensation of beam drift by enabling up to ±500 µm of positional displacement parallel to the optical axis. They are antireflection (AR) coated for one of five wavelength ranges: A (350 - 700 nm), B (650 - 1050 nm), C (1050 - 1620 nm), D (1650 - 3000 nm), or E (2000 - 5000 nm). Please see the Graphs tab for more details on the AR coating options. The FBSM Photodiode Mount allows our S130 Series Slim Photodiode Sensors to be mounted vertically into FiberBench systems.

The XY Tweaker Module consists of a precision-polished, AR-coated, plane-parallel plate mounted on a magnetic ball and socket for 360° rotation. The module allows for quick and precise displacement of a beam parallel to the optical axis, thus enabling several hundred microns of positional correction in increments of roughly 10 µm depending on the dexterity of the user. The plates are offered with a thickness of 2.5 mm and can be rotated and tilted in nearly any orientation. The beam is consequently displaced parallel to the optical axis by as much as 500 µm, as shown in the graph to the right. However, the performance of the AR coating on these optics deteriorates at angles of incidence beyond 30°. For general information about optical coating performance, please see our optical coatings guide.

Aperture Plates are a useful tool for system alignment or to measure beam size. The aperture plate should be mounted into the Ø1/2" optic mount (as shown in the image to the right) and then used to establish an optical center line in a FiberBench system. It is also useful for blocking stray light or other unwanted light in an optical system. ![]()
These IR alignment disks are ideally used as drop-in tools to simplify active alignment of IR and visible setups. A small Ø1.5 mm hole at the center enables beams to be aligned with the optical axis of our mounts or lens tubes. The active material on the VRC4D05 does not require charging and will emit light persistently when exposed to light in the 790 - 840 nm, 870 - 1070 nm, or 1500 - 1590 nm spectral region. The active material on the VRC2D05 requires charging by visible light. When charged and exposed to light in the 400 - 640 nm or 800 - 1700 nm spectral region, the disks will emit light. ![]() ![]() Click for Details S130C Photodiode Sensor Mounted in FiberBench System Using FBSM Adapter
The FBSM FiberBench Mount enables stable mounting of our slim photodiode sensors into our FiberBench systems. A side-located setscrew with a 0.050" (1.3 mm) hex can be used to lock the sensor in place. The mount has dowel pins for compatibility with FiberBenches and an optical axis height of 0.56" (14.2 mm) to match other FiberBench components. The target around the aperture uses the same material as our VRC2 Laser Viewing Card and is sensitive to light between the wavelength ranges of 400 - 645 nm and 800 - 1700 nm. | ||||||||||||||||||||||||||||||||||||||||
