OFS offers a suite of optical fibers, cables, and custom connectorized probes for delivering high laser powers for medical and industrial uses. We offer reusable fibers for aesthetic laser treatments and disposable fibers for urology. Industry uses our fibers in their lasers for cutting, welding, and etching.
Our HCXtreme™ Optical Fiber product line for high power under tight bends offers fibers in a selection of core sizes and numerical apertures, addressing the need to transmit high laser powers at the same time the fiber is subject to extreme bending conditions. Additionally, because many of these fibers are intended for intra-body use, they are biocompatible, non-toxic, and sterilizable.
Other large core HCS® optical fibers are available for specific applications. OH content, numerical aperture, core size, cladding and buffering materials can all be adjusted to meet specific needs.

Beamsplitters are used to reflect a certain percentage of incident energy, while transmitting the remaining energy. In most cases, beamsplitters are angle, wavelength, and polarization sensitive.
Most beamsplitter coatings are highly polarization sensitive. Thus, if the source’s polarization state varies with time, as in some randomly polarized lasers, the beamsplitters transmission will also vary with time.
The beamsplitters described here are designed for use at 45° angle of incidence and 10.6µm wavelength. At this angle of incidence, there can be significant differences in the transmittance/reflectance values for s and p-polarizations. It is essential that the laser’s polarization state be specified when ordering these optics. (See our Polarization tutorial for definitions of s and p polarizations.)

PPC beamsplitter cubes are derived from a unique combination of IBS coatings, ultraprecise fabrication capabilities and our epoxy-free bonding technology--Chemically Activated Direct Bonding (CADB) which results in zero-bondline thicknesses. In addition to the standard sizes and wavelengths shown, we can produce high-energy cube beamsplitters from 1x1 mm2 in size, and in a wide variety of materials including fused silica, BK7, YAG and other optical glasses and crystals.
Whether you need 10 or 10,000 pieces, our precision wafer-based processes result in high yields and competitive costs, especially at higher volumes. These high-precision assemblies have been widely used in telecommunications, semi-conductor and biomedical applications where transmission efficiency, extinction ratio and wavefront quality are all critical specifications.
Call us for more information on high-energy narrowband and broadband polarizing beamsplitter cubes for other wavelengths from 266nm to 2200nm, or to discuss your requirements for custom waveplates, polarizers and micro-optic assemblies.

These are thin film polarizers constructed as a cube. Thin film polarizers utilize the polarization which occurs on reflection from a plane surface. By combining a large number of such surfaces in a stack it is possible to obtain useful extinction ratios. The s-polarization is more than 99% reflected while the p-polarization can be suppressed in the reflected beam and become 95% transmitted. Thin film polarizers can be optimized for a particular wavelength to give superior performance for laser applications.

Thin Film Plate Polarizers and Dichroic Beamsplitters
Thin-film plate polarizers utilize our advanced ion-beam-sputtered (IBS) coating technology to achieve high-power performance and guaranteed transmission at a specific angle of incidence, with no angle tuning required. By combining durable dielectric coatings with fused silica substrates, we produce robust optical components that are stable, easy to align and exhibit high laser damage thresholds in both reflection and transmission.
High energy plate polarizers separate s and p polarizations with an extinction ratio (Tp/Ts) of greater than 750 to 1000:1 in the transmitted beam. Thus, they are ideal for intracavity or extracavity high-power applications where fluences are greater than 500 mJ/cm2 and calcite or cemented cube polarizers cannot be used.
Among the many diverse custom optical components that PPC offers are diode-pumped Nd:YAG resonator mirrors, 50/50 non-polarizing beamsplitters and thin-film plate polarizing beamsplitters. For all the optical components we provide, we use only ion-beam-sputtered (IBS) coatings. The IBS coating process is both accurate and repeatable, resulting in precision coatings that are easy to clean, chemically resistant and insensitive to moisture and other environmental factors.

Beamsplitters are used to split or combine beams of light. Tower provides some standard beamsplitters, but most are custom made.
Plates are used for most laser applications as they exhibit low absorption. Cubes are a convenient, protected form for low power applications. The performance of the beamsplitters is a function of the beamsplitter coating.
Beamsplitter Cubes
These beamsplitters are based upon using two complementary prisms. The output beam, which is parallel to the input beam, is called the p-polarized beam, while the orthogonal output beam is defined as s-polarized.
Basic Specifications:
Material: BK7
Dimension Range: 3.2mm to 50.8mm
Surface quality: 60/40 scratch and dig
Principal transmittance: Tp > 95% and Ts < 1%
Principal reflectance: Rs > 99% and Rp < 5%
Wavelength range: 226nm to 2300nm
Beamsplitter Plates
Are primarily used to split or re-combine a beam of light, especially in high power lasers. When using beam splitter plates the two partial beams travel different optical paths. The optical paths depend on the incident angle and the thickness of the plates.
Basic Specifications:
Material: BK7
Diameter Range: 10mm to 50.8mm
Flatness: l /4 @ 632.8 nm per 25 mm
Surface quality: 60/40 scratch and dig
T/R: 50/50 ± 5%

Beamsplitters are designed to separate a single beam of light into two beams that are normal to one another. The intensity of the separated beams depends upon the type of coating and the specific properties of the light.
Most beamsplitters use dielectric coatings that are wavelength and polarization sensitive; therefore it is highly recommended that one look carefully at the transmission curves to ensure that the beamsplitter will perform as needed.
Cube beamsplitters with hybrid (dielectric/metal) coatings are relatively insensitive to changes over a broad range of polarization and wavelength, and our laser-line coatings are polarization insensitive at their design wavelength.
