PANDA PM Polarization Maintaining Optical Fibers

250-2500 nm; Reflectance Value 2-99%; Reflectance Tolerance at 600 nm ±2%-±5%; Reflective Area 50.8x50.8-610x610 mm; Dimensions 57x57x17-616x616x17 mmLabsphere’s Spectralon® diffuse reflectance targets are ideal for laboratory, production and field applications that require long exposure to harsh environmental conditions such as field validation experiments performed to collect remote sensing data. Because of the diffuse reflectance properties of Spectralon, these targets maintain a constant contrast over a wide range of lighting conditions.Spectralon diffuse reflectance targets are available in plates up to 610 x 610 mm, in white or gray material, and are mounted in a rugged anodized aluminum frame. Calibration data from 250 to 2500 nm, every 50 nm, is supplied with the targets. Calibration data is traceable to the National Institute of Standards and Technology (NIST). All targets are thermally and chemically stable and easily cleaned.Targets larger than 610 x 610 mm can be constructed and calibrated, and custom targets of various reflectance values are also available up to 3 x 3 m. Please contact the AMS Technologies reflectance target experts to discuss your customized diffuse reflectance target solution.Key Features:Durable and WashableWavelength Range: 250 to 2500 nmVarious Reflectance Values Available: 2% to 99%Reflectance Tolerance at 600 nm: ±2% , ±3% , ±5%Flatness Range over 350 to 760 nm: ±4% , ±5%Impervious to Harsh EnvironmentsThermally and Chemically StableReflective Area: 50.8 x 50.8 to 610 x 610 mmDimensions Mounted: 57 x 57 x 17 to 616 x 616 x 17 mmApplications: Backlight Illuminators; Environmental Test Targets; Laser Targets; Optical Reflectors; Remote Sensing Targets; Proximity Sensors; Light/Sensor CompensationPlease note that Labsphere products are available from us only in Denmark, Finland, Iceland, Italy, Norway, and Sweden.

PMF/QPMF polarization maintaining (PM) fibers come in a variety of fiber sizes, operating wavelengths, and fiber types, and can be assembled into patchcords or more complex fiber optic components to suit your needs. OZ Optics categorizes fibers based on fiber type, operating wavelengths, core/cladding size, jacket diameter, and numerical aperture (NA). OZ Optics’ PMF/QPMF polarization maintaining (PM) fibers are a special variety of single mode (SM) fibers, designed to maintain the polarization properties of linearly polarized light sources, provided that the light is launched along either the slow or fast axes of the fiber. The most common method to do this is by adding two stress applying parts (SAP) on either side of the fiber core. OZ Optics’ standard PM fibers use a PANDA fiber geometry, with two circular stress rods. OZ Optics can provide fibers with other geometries, such as Bow-tie PM fibers. Like OZ Optics’ single mode fibers, the wavelength range is limited by their cutoff wavelengths and bend sensitivity at long wavelengths. OZ Optics offers special broadband RGB PM fibers for visible light applications, able to transmit light from 400 nm to 650 nm. Standard PM fibers (PMF) normally have a germanium doped core with a pure silica cladding, while for wavelengths shorter than 600 nm, OZ Optics instead uses fibers with a pure fused silica core with a fluorine doped cladding (QPMF fibers). For many high-power applications transmitting tens of Watts of optical power, standard single mode fibers are not suitable because of their small core size. On the other hand, multi mode fibers suffer from speckle patterns and large beam sizes. Large mode area (LMA) fibers offer a compromise by giving a large core size for high power handling at the expense of a lower numerical aperture, making them more sensitive to bending losses. In many cases, these fibers are not truly single mode, but are better described as low-order multi mode fibers. However, by carefully controlling how light is launched in these fibers and how much they bend, one can transmit nearly single mode light, thus generating output beams that can be focused to the small spot sizes needed for laser marking, welding and machining operations.
