Beamsplitters & Polarizing Optics

Beamsplitters & Polarizing Optics 

In order to properly manipulate a light energy, many different combinations of beamsplitters are required as well as 

laser mirrors. Our beamsplitters come with multiple categories; such as, energy beamsplitters, dichroic beamsplitters, 

or even Fabry-Perot etalons. 

Controlling polarity of the incident light energy should be considered when a light travels in angles other than the 

normal to the optics plane. Lattice Electro Optics offers a variety of polarizing optics and devices. They are polarizing 

or non-polarizing beamsplitters, calcite polarizers, waveplates, etc. 

If you need a special beamsplitter or polarizer, please contact our application engineers who are only one phone call 

away. Sometimes, you may need exotic optical materials to satisfy your needs. We are ready to assist you in this 

case, too.

Lattice’s high energy beamsplitters are used to split the incoming energy into two or more beams with 

different angles. Also, they can be used as beamcombiners. The second side is normally coated with high 

power antireflection (AR) coating to ensure no ghost image would appear.

Lattice’s thin film polarizers are designed to 

provide the maximum extinction ratio at near 

Brewster’s angle. Therefore, angle tuning may 

be required to optimize the highest extinction 

between transmitted and reflected beams.

SE 

Etalon 

Lattice’s solid etalons are based a Fabry- 

Perot interference principle. Their substrate 

is highly polished UV grade fused silica to 

ensure near zero wedge effect and the high 

power reflectance coatings are provided on 

both surfaces to maintain certain finesse.
