At the core of the PZ2 high-efficiency fiber stretchers is a fiber wound piezoelectric element for use in a wide range of optical interferometric measurement and sensing system applications. The PZ2 is ideal for use in OCT (Optical Coherence Tomography) and OCDR (Optical Coherence Domain Reflectometry) applications requiring scattering or boundary definition measurements. Optiphase’s expertise in the design, manufacture and use of all-fiber interferometers has produced a unique multi-layer winding approach resulting in an enhanced modulation function while maintaining a high operational frequency. PZ2 high-efficiency fiber stretchers are available with single mode (SM), commercial polarization maintaining (PM, Panda or Bowtie) or SM reduced cladding (RC) fiber types PZ2 high-efficiency fiber stretchers are available in two versions: Housed in an enclosure with connectors, making set-up and use quick and easy Bare lead fiber stretcher, not enclosed and including a convenient mounting kit consisting of a top-mount aluminum retainer and two silicone rubber pads - the mounting kit includes top or bottom mount Optiphase fiber stretchers are unique in that they do not require proprietary drivers. For most low-voltage applications (<±15 V) Optiphase stretchers can be driven by standard electronics such as signal generators, op-amps or other laboratory equipment without modification.

405-980 nm; Max. Optical Output Power 40-12 mW; Beam Diameter 0.75-4 mm; Power Stability <0.5%; Fiber Type SM, MM, PM Blue Sky Research’s FiberTec II™ series of high-performance, fiber-coupled diode laser modules incorporates highly integrated, sophisticated electronics for laser drive, protection, modulation and feedback functions. It has been optimized to meet the demanding performance requirements of applications that include medical, life sciences and automated instrumentation. This ultra-compact stand-alone assembly is RoHS compliant and can be ordered with a variety of collimation optics which allow easy integration into your system. A wide variety of wavelength and power options are available including the FiberTec II SLED series covering the visible to near-infrared wavelengths and FiberTec II laser diode modules which include 405, 488, 532 and 635 nm wavelength products. The FiberTec II lasers utilize several distinct technical approaches compared to other laser diode modules. Blue Sky Research’s patented micro lens approach optimizes the efficiency of coupling power into the fiber, allowing to drive the lasers less hard than competitors, which results in more stable power output over time and temperature. This means that with a FiberTecII product you’ll never have to re-align your fiber, as proven by Blue Sky Research with hundreds of thousands of hours of real time test data and extreme environmental test. In the FiberTec II series, the thermoelectric cooler (TEC) stabilizes laser power output and lasing wavelength over varying operational temperatures. Power stability is better than 0.5% over any 1-hour period. Our highly integrated electronic control is entirely contained within the laser module and no separate control box required. The lasers require DC power for operation. Output options include polarization maintaining (PM) fiber (typical extinction ratio of 100:1) and single mode or multi mode fiber. Termination options include fiber connectorization or collimation optics with diameters ranging from 0.8 to 3.3 mm. For the FiberTEC II series of fiber-coupled diode laser modules the dedicated power supply CLPS is available as an accessory. This device provides up to 2.5 A of current for laser diode and TEC and allows the operation of the FiberTEC II series from standard power sockets with 100 to 240 VAC.

Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless Steel Fiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11. Additionally, the fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.

At the same time, the diodes retain the low-noise, low-capacitance, and fast rise and fall times characteristics. To help simplify many design needs, these APDs are also available in Excelitas’ high-performance hybrid preamplifier module type C30659 series, as well as the preamplifier and TE cooler incorporated module type LLAM series. In addition, these APDs are also available with built-in thermo-electric cooler for easier temperature control.

350-2200 nm; Core Diameter 2-20 µm; Cladding Diameter 125, 130, 250 µm; Mode Field Diameter 2.3-10.5 µm; Numerical Aperture 0.08-0.2; Polarization Crosstalk <-20, <-25, <-30 dB OZ Optics offers a wide range of optical fibers suitable for many applications. 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.
