Where to Buy Beam Splitters

A beam splitter is an optical component used for splitting light into two separate beams, usually by wavelength or polarity. It can also be used, in reverse, as a beam combiner, to join two light beams into one. These specialty mirrors have applications in many fields, including laser, semiconductor and photonics instrumentation.

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.

Custom designed beam splitters for visible and IR applications are a particular specialty. We feedback preliminary performance data in Excel format as part of the quoting process, the link above gives specific examples. Contact us today for expert advice on your needs.

Shalom EO offers the stocked and custom high power narrow band laser line and broad band Polarizing Cube Beamsplitters (PBS), with typical wavelengths of 355 nm, 405 nm, 532 nm, 633 nm, 780-808 nm and 1064 nm, damage threshold of 10 J/cm² at 1064 nm, 10 ns, 10Hz pulses. The extinction ratio is 1000:1. The interface of these beamsplitter cubes is based on an epoxy-free optical contact bonding, which minimizes absorption and scattering loss. It is thermally stable with high transmission and minimal beam displacement. Besides the high power PBS, Shalom EO also offers the general power low cost PBS and non-polarizing beamsplitters.

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.

Knight Optical provides plate beamsplitters in economy, standard and precision ranges. With 30/70, 50/50 and 60/40 ratio available in the visible, NIR and Telecom wavelength regions. Custom beamsplitters are also available including polarising cube beamsplitters.

DayOptics produces polarizing cube beamsplitters with epoxy interface. Coatings are available for a wide range of operation wavelengths.

Laserton offers various types of beam splitters, including lateral displacement polarization beam splitters, polarization and non-polarizing beamsplitter cubes, beamsplitter plates, pellicle beamsplitters and variable beamsplitters/attenuators.

Our Femtoline beam splitters are designed for use 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 the Nd:YAG laser fundamental wavelength and its harmonics.

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).

Perkins Precision Developments (PPD) manufactures polarizing and non-polarizing beam splitters, beam splitter cubes, dichroic laser mirrors, prism polarizers, partial reflectors and output couplers for both R & D and OEM applications. Because we utilize Ion Beam Sputtering (IBS) coating technology, our beam splitters and beam splitter assemblies are environmentally stable, thus there is no spectral shift caused by either time, moisture or temperature.

As with all of our precision laser optics and optical assemblies, PPD's laser-line and broadband beam splitters and output couplers exhibit both low absorption and high damage thresholds (>20 J/cm²!), making them ideal for use with high energy Nd:YAG and fibers lasers as well as other high-power pulsed and CW laser systems.

Custom dielectric beam splitter coatings and low-loss anti-reflection (AR) coatings can also be deposited on customer supplied substrates, including flats, curves and prisms.
