PFG - Optical Polarizer Optics

Our company, PFG Optics, specializes in the production of customized thin film polarizer products that boast an unparalleled combination of characteristics, including a high extinction ratio, elevated damage threshold, minimal loss, superior mechanical durability, and an extended operational lifespan. Our range of polarizers encompasses a wide spectrum of wavelengths, including ultraviolet, visible, and mid-wave infrared, and boasts a diverse array of split ratios. In addition to our polarizer offerings, we also manufacture an array of other optical components, including optical lenses, beam splitters, and optical prisms. Adhering to best practices honed over decades of experience, we employ a variety of techniques, including tight centering, truncation, high included angles, and long radii, to ensure efficient and timely production. As a leading polarized optics manufacturer, we possess a vast library of test plates and employ state-of-the-art Zygo interferometers, all equipped with complete reference spheres for precise surface measurement.

As a leading manufacturer of high precision optical components, we specialize in the production of a diverse array of devices that generate or manipulate polarized light waves. Specifically, we offer a comprehensive range of polarizer optics, including dichroic sheet polarizers, cube or plate beamsplitters, lateral polarizers, professional circular polarizers, Glan laser polarizers, ultrafast polarizers, and more. These polarizers are based on one of the following four physical phenomena: reflection, selective absorption, scattering, and double refraction.

• Reflection – as seen in the example of unpolarized sunlight impinging upon a horizontal glass plane, results in the polarization of light through impingement upon a reflective surface.
• Selective absorption – makes use of an anisotropic material that selectively absorbs one of the perpendicular electric fields while allowing the other to pass through undisturbed.
• Scattering – occurs as unpolarized light rays travel through space and pass through molecules, resulting in linear polarization along the electron vibration plane.
• Double refraction – the polarizer is composed of a material that exhibits two indices of refraction, and the polarization state and direction of the incoming light affects the refraction and resulting polarization state after passing through the material.

• Our company is committed to producing the highest quality optical polarizers by utilizing cutting-edge technology and rigorous quality control protocols.
• Polarization-Based Imaging : Polarizers are used in cameras and other imaging equipment to control the polarization of light, which can be used to reduce glare and improve image contrast.
• Optical Communications : Polarizers are used in optical fiber communication systems to improve the signal-to-noise ratio and reduce crosstalk.
• Display Technology : Polarizers are used in LCD and OLED displays to control the polarization of light and improve the visibility of the display.
• Industrial Sensing : Polarizers are used in industrial sensors to detect the position, orientation, or movement of objects.
• Medical Equipment : Polarizers are used in medical equipment such as endoscopes and microscopes to improve image contrast and reduce glare.
• Spectroscopy : Polarizers are used in spectroscopy to analyze the properties of light, such as its wavelength and intensity.
• Metrology : Polarizers are used in metrology to measure properties such as the birefringence and dichroism of materials.
• Laser Systems : Polarizers are used in laser systems to control the polarization of laser beams, which is important for many laser applications such as laser cutting and welding, laser printing, and laser-based medical treatments.
• Solar Energy : Polarizers are used in solar energy systems to improve the efficiency of solar cells by controlling the polarization of light.
• Military and Aviation : Polarizers are used in military and aviation equipment to improve visibility and reduce glare, such as in helmet-mounted displays and night vision goggles.

A polarization optic is capable of selecting or changing specific polarizations. We can provide a diverse portfolio of polarizing cube beamsplitters, waveplates, and linear polarizers which operate over IR, UV, and visible spectral ranges. Quarter-wave and half-wave plate polarizer can come in achromatic, multiple-order, or zero-order versions. Thin-film polarizers can be utilized in high-energy Nd: YAG applications, as well as Ultrafast lasers and Ultrashort pulse, uses. Reach out to us for your optical polarizer needs.

The polarization of light, both manipulating it and understanding it, is absolutely critical for optical uses. Often we see optical designs ignoring its polarization, instead of paying attention only to the intensity and wavelength. Polarization is an essential aspect that can have an effect on optical systems that are not even specifically measuring it. It can affect many things, such as preventing unwanted back reflections, altering filter cut-off wavelengths, and even changing the focus of laser beams. Metrology applications benefit from light polarization as well, through pharmaceutical ingredient analysis, biological microscopy, and stress analysis of materials like glass or plastic. Materials can absorb varying degrees of different polarizations, which is a critical aspect of 3D movies, glare-reduction eyewear, and LCD screens.
