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. |

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.
