Beam splitters are optical devices that split a beam of light in two. It is the crucial part of most interferometers.

This beam splitter plate is used not only for 780nm wavelength, but for 650nm or 405nm wavelength.

This beam splitter can be used for dual laser wavelengths (DVDs/CDs ). Transmission and reflection ratio for each wavelength are designed upon your request.

• Wavelength 13.5nm
• Transmission/Reflection ≥30%
• Divergence Comparison 50%
• Substrate: Si
   * Under Development

Polarizing Beam Splitter (PBS) divides an incident beam into P and S polarizations. PBS has a function to divide a beam for recording and playing signals in optical pick-up units.

Polarizing Beam Splitters for Fiber Optics provide isolation with the P-/S-polarization extinction ratio of 1/10,000 or more.

Polarizing Beam Splitters for Fiber Optics provide isolation with the P-/S-polarization extinction ratio of 1/10,000 or more.

This Polarizing Beam Splitter is used especially for high precision LCOS projectors.This beam splitter is made of low photoelastic coefficient glass to avoid heat influence and has low dependency on incident angle.

This Polarizing Beam Splitter Cube was developed specially for Blu-ray Disc, HD DVD applications.

In the latest optical disk technologies (Blu-ray Disc, HD DVD) that use blue diodes, adhesives that have been used without any problems up to now have reached a limit in their reliability due to making luminous wavelengths shorter and the increase in energy density. In NITTO OPTICAL, a beam splitter bonding method with optical contact was developed as a solution for this problem.

Non-polarizing Beam Splitters (NPBS) are a specific type of beam splitter which can equally divide
P and S ratio. It can maintain incident light's Polarization component ratio when it separates.

Polarizing Converter for LCD projectors divides the incoming random light into P or S polarization in order to increase light efficiency. Either the P or S polarization light passes through 1/2 wave plate and the light is unified to one polarization.

Wave plates change the polarization optical path difference that oscillates in a perpendicular direction by 1/2 wavelength.

Wave plates change the polarization optical path difference that oscillates in a perpendicular direction by 1/4 wavelength.

Non-adhesive wave plates are ideal for the usage with high power laser. No deterioration of the glue due to the irradiation of high energy density beam at the bonded surface. Excellent performance in both UV and IR bands.

Non-adhesive agent bonding method; Ideal for the usage under high power laser (no damage or deterioration of bonded surface due to the adhesive agent), No UV absorption at the bonded surface occur to reduce the transmission.

Wollaston Prisms comprise two prisms of calcite or crystals cemented together. The ordinary beam in the first half of the prism becomes the extraordinary beam in the second half, and vice versa.

Double Wollaston Prism generates 4 optical fluxes which have 45 degree axis difference among each other. Used as an analyzer of ellipsometric optical systems, this prism acquires Stokes parameter at one time without using polarizing plate. NITTO OPTICAL produces Double Wollaston Prism with calcite.

These are polarizing prisms that comprise two crystals or calcites with double refraction and turn incident beam into linear polarized beam.

Rochon Prisms are used in applications where good polarization selectivity is required across a large range of wavelengths.

These are polarizing prisms that turn incident beam into linear polarization. The incident beam polarization becomes perpendicular to the output surface.
