Where to Buy Beam Splitters

Edmund Optics offers plate, cube, pellicle, polka dot, and specialty prism beamsplitters in a variety of anti-reflection coatings or substrates. Standard beamsplitters, which split incident light by a specified ratio that is independent of wavelength or polarization state, are ideal for illumination subassemblies or as one way mirrors. Dichroic beamsplitters, which split light by wavelength, are often used as laser beam combiners or as broadband hot or cold mirrors. Non-polarizing beamsplitters, ideal for laser beam manipulation, split light by overall intensity. Polarizing beamsplitters, often used in photonics instrumentation, split light by polarization state. Edmund Optics’ anti-reflection coatings are designed for the ultraviolet (UV), visible, or infrared (IR).

We offer Femtoline beam splitters designed to be used in femtosecond laser applications with fundamental wavelengths of Ti:sapphire and Yb:KGW/KYW lasers and their harmonics. Nd:YAG LaserLine beam splitters are designed for Nd:YAG laser fundamental wavelengths and its harmonics.

LASEROPTIK can produce beam splitters for a wide range of wavelengths from the mid-IR to the ultraviolet region.

Frankfurt Laser Company offers beam splitters based on diffractive optical elements. An input beam is replicated precisely in the pattern determined by the beam split up. The input beam can be any collimated laser beam of white light source with a beam diameter larger than 100 μm and smaller than the aperture of the element.

DataRay offers two unique beam splitters: the Polarization Preserving Beam Sampler (PPBS) and the Compact Beam Sampler (CBS) for various applications.

TOPTICA Photonics AG offers a wide range of optical fibers ideally suited for use with TOPTICAs lasers and FiberDock. These economically priced fibers cover a wide range of wavelengths. TOPTICA recommends to always purchase a fiber along with a laser and fiber coupler, as this ensures maximum fiber coupling efficiency. Also specialty fibers for power monitoring, beam splitting or combining are available with various ratios and also polarization maintaining.

VisiMax process beam splitter coatings are designed to address specific reflection and transmission ratios, wavelengths, angles of incidence (AOI), and polarization states, as well as conform to the index and temperature sensitivities of specific optical component materials. VisiMax can design beam splitter coatings for most optical materials including glass, plastics, molded polymer optics, and semiconductor materials. While VisiMax routinely handles many standard beam splitter designs such as 50/50, 60/40, and 70/30 R/T ratios, we can also design custom coatings to meet the particular requirements of your optical system.

Gentec Electro-Optics offers beam splitters used as optical attenuators for measurements on high-power laser beams.

We produce precision beamsplitters with multi-spectral and hyperspectral coatings. Our beamsplitters provide minimal beam deviation and maximal power throughput using adhesive free manufacturing techniques.

NIL Technology can design, prototype and manufacture fan out diffractive beam splitters meeting customer specifications. For DOE’s we routinely offer up to 16 levels and down to 200 nm feature size. Depending on the application more levels or smaller feature sizes can be obtained.

Optimized beamsplitter designs from G&H demonstrate superior laser damage performance for each unique wavelength, split, and incident angle combination. High-energy coatings are optimized to accommodate specific application requirements.

For maximum power handling, we recommend optically contacted cubes or plate beamsplitters. For durability and handling, G&H suggests cube beamsplitters.

Meeting a wide range of specifications, Knight Optical offers both plate and cube (non-polarising and polarising) beamsplitters for ultimate precision when splitting incident light beams. Offered in a choice of three grades, plate beamsplitters can be supplied in standard, economy and precision λ/4 options.

Optometrics, a Dynasil company, offers standard and custom plate, polka-dot and transmission grating beam splitters with constant reflection to transmission ratio over 250 to 2000 nm. Available on fused silica or SCHOTT B270® ultra-white glass. Transmission grating beam splitters are ideally suited for He-Ne laser beam division and multiple laser line separation.

Artifex Engineering offers high quality custom beamsplitters tailored to your requirements. Coatings for single wavelengths or broadband are possible in the UV-NIR range. We offer beam splitters as plates, cubes and pentaprisms. Artifex offers unpolarized, non polarizing and polarizing versions for the three types. Visit our product page for more information. We look forward to your inquiry.

Shanghai Optics manufactures custom cubic beamsplitters, plate beamsplitters, and lateral displacement beamsplitters. All our beamsplitters are made of high quality glass, with high surface quality to allow tight tolerance on all parameters.

Schäfter+Kirchhoff offers compact, rugged and highly efficient and fully fiber-coupled opto-mechanical units for splitting fiber coupled radiation for the configurations 1 ⇾ 2 and 2 ⇾ 2.
