SciMerTech is a science centered company with core competecies in analytical software technologies and precision optics. We design our products and services to help and support people and globe with our technologies. Here we introduce our state of the art precision optics line manufactured on our own production line. Our main optics line contains  Beam splitters, Neutral Density Filters, Prisms, Lenses, Mirrors, and Wollaston Prisms. Here, below as the first of our product line we show the performance of the wollaston prisms.


Wollaston Prisms

Wollaston Prisms separate the unpolarized light into two orthogonally polarized outputs with an angle of separation based on the prism material, typically from 1 to 20 degrees. Currently, two materials in use are Quartz and calcite. Typically, the extinction ratio is more than 10000:1. The crystal quartz and calcite are capable on the wavelength range of 660nm to 1550nm and theoretically from 400nm to 2000nm and 350nm to 2300nm, respectively.

Calcite polarizers are birefringent calcite crystals. Due to the birefringent nature of calcite, waves polarized in the direction of the optical axis propagate with a different index of refraction than waves polarized orthogonally to the optical axis. The birefringence separates the two orthogonal polarization states of an incident beam. A calcite polarizer can be designed as either a polarization splitter/combiner or as a polarizer element that removes the angled, orthogonally polarized component of a beam. Our calcite polarizers are typically built out of two prisms, as shown in the drawing to the right. Since calcite is a soft crystal that is easily damaged, almost all calcite polarizers can be offered in metal housings. With convenient threading and adapters.

Test Note: The crystals were tested at two different wavelength with circularly polarized light and at one wavelength with a polarized light.

When tested both the crystals at polarized single mode 1330nm the intensity ratio of the orthogonal pairs were 10000:1

Optical Patch Chords

SciMerTech offers single mode fiber optic patch cables with a variety of connector options, including Ferrule Coupled/Physical Contact (FC/PC), Ferrule Coupled/Angled Physical Contact (FC/APC), and hybrid FC/PC to FC/APC and FC/PC to SMA. Also available are single mode patch cables with AR-coated FC/PC or FC/APC connectors for improved fiber-to-free-space coupling, low-insertion-loss patch cables and mid-IR patch cables.

Single Mode FC/APC

The single mode fiber optic patch cables are FC/APC terminated on both ends. Making the FC/APC ideal for systems that are sensitive to back reflections. The narrow key connector utilizes a ferrule that has an 8° angle polished tip, ensuring typical return loss of 60 dB. Each cable is FC/APC terminated on both ends, and cables are available in 1, 2, 5, or 10 m lengths. 

Each patch cable includes two protective caps that shield the ferrule ends from dust and other hazards. Mating are available to connect FC/APC to FC/APC connectors. These mating sleeves minimize back reflections and ensure proper alignment of the cores of each terminated fiber end.

SciMerTech also offers low insertion loss patch cables, which feature single mode fiber with tighter core concentricity specifications for lower insertion loss and higher transmission. We also offer AR- coated Single mode Patch Cables, which have an antireflective coating on one fiber end for higher performance in fiber-to-free space applications.
