FPS-001 Phase Shifter

Inside Diameter 15 to 450 µm; Outside Diameter 90 to 673 µm; Coating Polyimide; Temperature Range -190 to +350 °C; Tensile Strength >600 kpsi Fiberguide’s fused silica capillary tubing is used for micro-fluidics applications and in gas chromatography (GC) separation columns. These capillaries are coated with polyimide for mechanical stability and versatile uses. With inert surfaces and high purity, Fiberguide’s capillary tubing solutions provide a very high phase stability, while their peak mechanical stability leads to greater yield and more cost-efficient tubing. Based on the great flexibility combined with high tensile strength (>600 kpsi), these capillary tubing solutions are pressure resistant to 4,500 psi and allow very small radii during coiling with no kinking. They are impervious to chemicals, allowing usage in harsh environments. A wide range of internal and external diameters with tight tolerances allows users to select a capillary tubing solution that best suits their flow rate requirements. All capillaries can be easily cleaved or cut, allowing to adjust exactly the column length needed for interfacing. While the mirror smooth inner surface provides stable laminar flow profiles and good adherence, the capillary tubing solutions’ Polyimide coating is very durable and abrasion resistant.

Wavelength 400 to 1550 nm; Fiber Types All Silica, Plastic Clad, Round or Square Core; Fiber Core Size 100 to 400 µm; Buffer Types Polyimide, Nylon, Tefzel, Acrylate; Power Supply 5 V Fiberguide’s proprietary de-speckler technology averages the modal noise within an optical fiber. This reduction in speckle is an ideal choice for fiber assemblies used in the life sciences, digital laser projection, interferometry, laser beam homogenization, lithography and metrology. For many fiber coupled applications, modal noise interferes with optimal performance. Fiberguide has developed a small and compact de-speckling system which maximizes performance and reliability.

Delivery System consisting of a laser to fiber coupler, fiber optic patchcord, fiber optic collimator, and fiber optic line generator; Power Transmission ≤1 to ≤ 20 W In flow visualization systems, a visible wavelength laser beam is coupled into an optical fiber, recollimated at the fiber output, and then sent through a lens, generating a line. This line of laser light is then shone through the flowing liquid under inspection. Any particulate matter present, or changes to the flow pattern within the fluid, causes fluctuations in the output beam pattern which are visually observed. OZ Optics offers complete delivery systems for flow visualization, consisting of a laser to fiber coupler, fiber optic patchcord, fiber optic collimator, and fiber optic line generator. The line generator uses a Powell lens. Compared to simple cylindrical lenses, this Powell lens transforms a collimated beam into a line with a uniform output intensity along its entire length. Fiber optic delivery systems are available for a wide range of wavelengths. Other wavelengths are available on request. The maximum power transmission possible depends upon the fiber size chosen 4/125 fiber can handle 1 W to 3 W, 10/125 fiber can handle 3 W to 5 W, 25/125 fiber can handle 5W to 10 W, and 50/125 fiber can handle 10 W to 20 W. For best repeatability and stability, FC connectors are recommended for the fiber couplers and collimators. Pigtail style couplers and collimators are also recommended.By choosing different focal lengths for the collimating and Powell lenses, different line widths and fan angles are possible. Standard line widths for singlemode fibers are 0.8 mm and 1.2 mm. Standard fan angles are 10°, 30° and 45°. Contact us for further information on available line widths and fan angles. Key Features: Uniform Output Intensity over Entire Length Rugged and Compact Design Low Insertion Loss Visible Wavelength Range: 400 to 700 nm Wide Fan Angles Available: 10 to 75 degrees Applications: Flow Cytometry, Particle Measurement, Imaging Systems

Fixed or Variable; Receptacle or Pigtail Style; Fiber Type SM, MM, PM; 400 to 1600 nm; Back Reflection 25 to 60 dB OZ Optics’ FORF series of fiber optic reflectors are used to reflect the light emerging from a fiber back in the reverse direction. They are used to build fiber interferometers, or with fiber fused splitters to measure back reflection within fiber optic components. They can also be used to measure the sensitivity of sources to back reflection from other devices, by providing reference reflection levels. This is very useful for deriving back reflection specifications for transmitters. Fiber optic reflectors consist of a fiber optic collimator and a mirror. The fiber output is first collimated, then it strikes the mirror and is reflected back into the collimator. The angle between the collimator and the mirror is adjusted using OZ Optics' patented tilt adjustment technique, until as much light as possible is reflected back into the fiber. Using this technique, reflectors with typical losses of only 0.6 dB can be constructed. A variable reflector is available that includes a blocking screw, to obtain variable reflection levels. This is achieved by partially blocking the collimated beam between the lens and the mirror. Both connector receptacle style and pigtail style reflectors are available. Connector receptacle style reflectors come with a female connector receptacle to allow the fibers to be easily changed. Pigtail style reflectors come with a fiber of your choice permanently attached to the collimating lens. This type of reflector is recommended for optimum coupling efficiency and stability. The other end of the fiber can be terminated with your choice of connector. OZ Optics also provides fibers with coated ends. Gold coatings are used to provide excellent broadband reflection for infrared wavelengths. Other coating materials are available for other wavelengths. The ends can have total reflecting, or partial reflecting/partial transmitting coatings. Contact AMS Technologies for further information. Reflectors are available for wavelengths from 400 to 1600 nm. Reflectors that operate at both 1300 and 1550 nm are available, with only a slight difference in insertion losses at both wavelengths. Broadband reflectors using achromatic lenses to collimate light at different wavelengths are available. Partially reflecting mirrors are also available, to partly transmit the light. The transmitted light can be coupled into an output fiber as an option, thus forming an in-line reflector. Contact AMS Technologies for further details. Key Features: Wide Range of Available Wavelengths Available in Single Mode (SM), Polarization Maintaining (PM) and Multi Mode Versions Low Insertion Loss Compact Housing Partial Reflectors Available Applications: Interferometric Sensors; Circulators; Return Loss Testing; Reference Beam Power Measurements

780-1550 nm; Total Phase Shift >65π; IL <0.5 dB; RL >50, >55, >58 dB; PDL <0.05, <0.1 dB; Residual Amplitude Modulation ±0.01 dB Coherent or interferometric sensor systems, such as distributed acoustic sensors (DAS), often require a low-loss, low-cost phase shifter or modulator to obtain the desired sensing signals. General Photonics’ FPS-002 is an all-fiber device that shifts or modulates phase shifts up to 75π at frequencies from DC to 20 kHz. The FPS-002 phase shifter requires a lower half-wave voltage than the FPS-001 phase shifter module: only 2 V compared to up to 20 V. Like the FPS-001, it is an all-fiber design and offers the benefits of low loss and back reflection. Two different size packages (small frame or large frame) are available to accommodate the bend diameter requirements of different fibers.

1260-1650 nm; Delay Range >3 mm; RL >65 dB; Fiber Type SMF-28, Other; IL <0.2 dB; PDL <0.05 dB General Photonics’ FST-001 is a piezo-driven fiber stretcher with an optical delay range of up to 3 mm. The device, including the piezo driver, is packaged in a metal enclosure. Each of the FST-001 fiber stretcher’s four piezos can be controlled independently, allowing high resolution or large stroke. Piezos can be controlled with an analog signal or a 12-bit TTL signal. Under analog control, the driving circuit acts as a 4-channel voltage amplifier with 30V/V amplification. Alternatively, the output voltage can be controlled by a computer equipped with a digital I/O card, or by a microprocessor.
