Arcoptix Polarization State Generator (PSG)
from Arcoptix S.A

Most SOP generators found on the market are expensive and based on fiber optics technology. The Arcoptix Free space Polarization State Generator (PSG) or also called Eigen state generator (EGS), is a transmitive free space optical system that permits to generate any arbitrary polarization state...

  • Surface Flatness: λ/4
  • Wavelength Range: 350 to 1000
Glan Taylor Polarizer
from Dayoptics, Inc.

Glan Taylor polarizer is made of two same birefringent material prisms that are assembled with an air space. Its length to aperture ratio which is less than 1.0 makes it a relatively thin polarizer. The polarizer with no side escape windows is suitable for low to medium power application where the... [See More]

Glan Laser Polarizer
from Artifex Engineering

Glan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allows the rejected beam...

Achromatic Air-Spaced Waveplates
from EKSMA OPTICS

Achromatic waveplates are made from two different materials: crystal quartz and magnesium fluoride with highly efficient broadband antireflection coatings in an air spaced design. Retardation tolerance of our achromatic waveplates is better than λ/100 over the entire wavelength range. The... [See More]

  • Optical Polarizer: Waveplate / Retardation Plate
  • Clear Aperture: 12.7
Dual Wavelength Waveplate -- W-LPD212
from Ross Optical Industries

The low (multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This results in a single, physically robust component with desired performance. However, even small changes in wavelength or temperature will result in significant changes in the... [See More]

  • Wavelength Range: 266 to 1550
Depolarizers
from Thorlabs, Inc.

At Thorlabs, we constantly reinforce our desire to serve at the pleasure of our customers. From this comes our desire to be connected to our industry in a way that far exceeds what would typically be expected of a vendor. Thorlabs lives this core principle by seeking to enhance, at every turn, the... [See More]

  • Wavelength Range: 350 to 1700
Achromatic Waveplates - Air Spaced
from Tower Optical Corporation

Tower ’s achromatic waveplate (AWP) is similar to a zero-order waveplate, which is made from two pieces of crystal quartz except that the AWP is composed of one piece of crystal quartz and one piece of magnesium fluoride, MgF2. Both of these materials are birefringent, however, by proper... [See More]
