780 nm; Linewidth 200 kHz; Output Power 80 mW; Threshold Current 70 mA; Slope Efficiency 0.8 W/A; Side Mode Suppression Ratio 50 dBToptica eagleyard’s Mini-ECL miniature external cavity laser is a single frequency laser diode with a super fine linewidth of typical 200 kHz and a collimated output. Stable performance is ensured by the integrated cavity in the hermetically sealed standard butterfly package with integrated temperature control and no moving parts. Moreover, wavelengths between 650 – 1100 nm are customizable upon request, opening more freedom across the spectrum. The standard product at 780 nm will mainly be used for spectroscopy (Rb D2 line), metrology and atomic clocks.The advantages of the Mini-ECL become very obvious when looking at the reduced complexity based on the integration of the cavity. Due to the ease of use, the robustness of the package and therefore scalability, not only research applications will benefit from this innovation but commercial and industry requirements are more easily fulfilled than with already available solutions. This will lead to outstanding results and applications along the value chain.Mini-ECL also serves as a perfect seeder for Toptica eagleyard's TPA series of tapered amplifiers, resulting in a MOPA system with up to 3 W single mode poutput power and a brilliant frequency stability inherited from the seeder. Key Features:Center Wavelength: 780 nmVery Small Linewidth for Precise Results: Typ. 200 kHzVery Good Side Mode Suppression Ratio (SMSR): Typ. 50 dBOutput Power: 80 mWForward Current: 180 mAThreshold Current: 70 mAWavelength Customization PossibleIntegrated Beam CollimationLow Complexity due to the Integration of the CavityRobustness due to Hermetically Sealed Butterfly PackageThermal Management by Integrated Thermoelectric Cooler (TEC) and ThermistorBeam Divergence Parallel (Slow Axis) & Perpendicular (Fast Axis): 2 mrad (FWHM)Package: Hermetic 14-pin ButterflyApplications: Spectroscopy (Rb D2 Line); Quantum Technology (Cold Atom), High-coherence Photon Source; Metrology; Atomic Clock  Please note that TOPTICA eagleyard products are not availble from us in Denmark, Finland, Iceland, Norway, and Sweden.

Polarized Diode Laser Sources; 635 to 2050 nm; Output Power 1 mW; Case 60 x 90 x 190 mm; Spectral Bandwidth <5 nm OZ Optics’ PFOSS series of polarized fiber optic sources are produced in a variety of wavelengths. PFOSS sources are available in three versions: Two receptacle versions, one with the polarization axis aligned with the keyway on the receptacle and a second receptacle style version with a rotatable polarizer, allowing one to adjust the polarization axis to any desired angle. Finally, a pigtail style version has a polarization maintaining fiber attached, with the output polarization aligned with the slow axis of the fiber As an option, OZ Optics can include a blocking style optical attenuator to manually change the output. Unlike electrical systems, this method of power control does not affect the spectral properties of the laser diode output. This ensures more repeatable results. While the PFOSS design is quite stable for standard measurements, sometimes reflections or temperature changes can affect the output power and wavelength for applications where stability is critical. OZ Optics recommends using angled connectors and receptacles for optimum stability. With the HIPFOSS series, highly stable polarized fiber optic laser sources using Peltier coolers and isolators are also available from OZ Optics. Key Features: High Polarization Extinction Ratio (up to 40 dB) Stable Output Wide Range of Available Wavelengths Rugged and Compact Design Wide Range of Connector Receptacles Available Optional High-power Version Optional Adjustable Output Power Applications: Extinction Ratio Measurements; Polarization Dependent Loss (PDL) Measurements; Product Manufacturing and Quality Control

Electromagnetic Type; Actuator Voltage 12 to 24 VDC; Load Switching Current 3 to 110 A RMS; Maximum Switching Voltage 4 to 50 kVA pioneer in the development of the original high voltage vacuum relay, Jennings Technology is still recognised around the world as a leading manufacturer of high voltage relays today. Jennings’ relays are noted for fast operating speeds and the ability to withstand high voltages and carry heavy currents (at frequencies up to 75 MHz), while maintaining low and stable contact resistance.Jennings vacuum relays are available in SPST (Single Pole, Single Throw) normally open (N/O) and normally closed (N/C) models up to 33 kV, as well as SPDT (Single Pole, Double Throw) configurations up to 30 kV and gas filled relays up to 70 kV. Latching relays are available in some models.The reliability of Jennings vacuum relays is second to none; many of these relays have guaranteed life ratings set in the multi-million cycle range. The relays' reliability coupled with their small size and high power handling characteristics make the use of Jennings relays in any mission critical application an obvious choice. Many of Jennings relays are fully Mil-Spec rated.Vacuum is the ideal dielectric for high voltage relay switching. It has extremely high voltage breakdown characteristics, a fast recovery rate (up to 10 kV per millisecond) and it provides an absolutely inert and non-reactive environment for switching contacts. If a load is switched, an arc will form. This arc will have a very low voltage of 18 to 23 V and be quite stable in comparison to an arc in air, which is another advantage of vacuum. The vacuum relay constant arc voltage acts as a current limiter and, in combination with the short arc time, generally offers less wear than other types of relays.Key Features: Extremely High Voltage Breakdown Characteristics Available in SPST N/O and N/C Models as well as SPDT Configurations Latching Relays Available in Some Models Contacts Remain Oxidation-free Small, Low-mass Actuators for High Operating Speeds Very Low Arc Voltage: 18 to 23 V Less Wear Than Other Types of Relays Test Voltage (at 60 Hz): 4 to 50 kV Peak Max. Continuous Current: 3 to 110 A RMS Applications: Airborne, Mobile and Marine Communications Equipment; Antenna Coupling; Tap Changing on RF Coils; Transmit/Receive Switching to an Antenna; Switching in Pulse-forming Networks; Heavy-duty Power Supplies

Interchangeable Fixtures for Connectors, Waveguides, Bare Fibers, Other; Film Size 4 Inch Diameter; Capacity up to 8 Components; Connector Apex Offset <50 µm; Connector Radius of Curvature 5-25 mm; Connector Protrusion/Undercut: 50--120 nm KrellTech’s NOVA™ automated polishing system provides maximum flexibility for optical surface processing and supports a variety of polishing applications from connectors to waveguides, and bare fibers to custom components. NOVA™ is scalable for R&D projects, high-volume production and the rigors of harsh environments and field installation. NOVA™ workholders feature KrellTech’s patented independent suspension at each connector position for controlled pressure and uniform contact. Combined with NOVA’s Microfeed™ fixture advancement, connector “airpolishing” and epoxy removal can be performed directly in the machine. Each position is optically aligned for optimal polish geometry using KrellTech’s patented process and calibration mechanism. Connector types can also be mixed and matched in a single fixture. NOVA’s versatility provides the ability to support the polishing of many photonic components. A quick change-out of workholder fixtures provides processing capability for waveguides, optical chips, PLCs, lenses and fiber arrays. Workholders utilize a unique holding mechanism that can secure a wide range of component dimensions. The polishing angle is adjustable and custom fixtures can be fabricated for specialized applications. Bare fiber can be polished at variable angles using specialized workholders and adapters. A variety of fiber types from standard single mode (SM) to polarization maintaining (PM) and sapphire to PCF can be processed into wedge and chisel tip shapes. A quick swap-out of adapters allow the polishing of fiber diameters from 80 um to >3 mm. NOVA™ features an intuitive user interface for creating polishing programs. All parameters including cycle time, pressure and speed settings are easily inputted for all component types and desired surface geometries. A unique “manual mode” allows the adjustment of polishing parameters in real-time during NOVA™ operation. This feature streamlines process development efforts and facilitates easy and quick program creation and refinement. A new NOVA™ operation software kit is available that upgrades NOVA™ polishers with the enhanced microfeed feature. This polishing routine provides greater programming flexibility for advancing components to the polishing surface at slower and more controllable rates. While version 1 NOVA™ software was limited to 10 pre-programmed microfeed rates, with the slowest being 100 µm/s, version 2 software allows to customize rates as slow as 5 µm/min. This yields precise removal of material stock and continual component advancement. The enhanced microfeed is ideal for larger optical surfaces, delicate bare fibers, and connector air polishing. V2 also provides the ability to create "pop-up" window prompts in between each polishing step, very useful as reminder to technicians to clean fibers, inspect polishing lengths, confirm geometry, etc. before initiating the next process step. New folder management allows programs to be organized according to connector types, fiber diameters, component, etc. Bare Fiber Coning and Chisel Option The optional Orbit™ bare fiber coning and chisel system enhances NOVA™'s bare fiber processing with conical and chisel tip shaping. Unique fiber tip geometries can be formed for lensing, sensing and light guiding applications. The fiber rotation module can be mounted on standard NOVA™ variable angle and waveguide workholders. Fiber "spin" speed is user adjustable and can be set for continual rotation or the unique "360 auto-reverse" motion that prevent fiber twisting and torquing. All variables are entered and selected via a touchscreen on the Orbit™ controller. When combined with NOVA™ Auto-Angle Workholders, Orbit™ precisely positions the polishing fixture at the designed angle on a repeatable basis. Inspection Options Optional video inspection systems monitor the polishing process and inspect the polished surface directly in NOVA™.  NOVA™'s Profile Videoscope allows the real-time monitoring of component polishing. This videoscope aids with bare fiber/component positioning and confirms process completion. Teamed with measurement software, this system verifies the endface geometry of a broad range of photonics components. Teamed with measurement software, this system verifies the endface geometry of fibers, waveguides and arrays. NOVA™'s Surface Videoscope allows the in-line inspection of polished surfaces while the component is still loaded in the polisher. This minimizes material handling and streamlines photonic production compared to the traditional process of transferring components to off-line inspection stations. Polishing and specification compliance can be determined in a single workcell.
