AGI Graded Index MM Fibers

Product information "AGI Graded Index MM Fibers"

Multi Mode, Graded Index; 850, 1300 nm; Core Diameter 50, 62.5 µm; Cladding Diameter 125 µm; Coating Acrylate, Polyimide, Aluminium, Gold; Numerical Aperture 0.20, 0.275

Fiberguide’s AGI series of anhydrous graded index multi mode silica core, silica clad, polymer or metal coated fibers feature a graded index profile instead of a step index profile. These fibers are primarily used in data transmission applications where more bandwidth is needed than step index fibers can offer. These fibers are available with acrylate coatings (-Y) and also high performance polyimide (-T), aluminum (-A) and gold (-G) coatings that allow them to exceed the temperature performance levels of standard fibers.


As a further option, AGI series fibers can be provided with a broad selection of shaped tips – standard configurations as well as custom designed shapes. Shaped tip fibers provide optimum control over beam delivery and/or increased efficiency of light collection.


AGI series fibers can also be end capped to achieve higher coupled power into a fiber core by reducing the power density at the air / silica interface, commonly the point of laser damage. End cap diameters and lengths are offered for select numerical apertures and fiber cores size, but can be easily customized for a variety of fiber types and specialized applications.


Additionally, all fiber types 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.

Lord FiVe Finned Tube Condensers and Evaporators
Tube Diameter 5 mm; Tube Material Cu, Al; Tube Matrix 19.05x12.70 mm; Fin Density 7-21 fpi; Fin Spacing 1.2-3.6 mm AMS Technologies’ customized condenser and evaporator offering is based on Lordan’s compact, lightweight Lord FiVE coil pattern with a 5 mm diameter rifled tube– the smallest and most advanced coil on the market today. With its small diameter tube, Lord FiVe provides excellent heat exchange performance while utilizing smaller amounts of refrigerant compared to the usual 3/8” pipes, making Lord FiVe condensers and evaporators for vapor compression circuits more environment-friendly and cost-effective. Lord FiVe condensers and evaporators are helium leak tested at 42 bar and are guaranteed to have less than 0,5 g refrigerant leakage per year. Its dense pattern (19.05 mm pitch and a depth of only 12.70 mm) allows Lord FiVe condensers and evaporators to fit into small areas while providing high heating and cooling outputs. Fin densities from 7 to 21 fpi (fins per inch) are available, as well as marine grade aluminium fins, coatings and other options. Finned height and length, number of rows, number of circuits, fan mount and access valve fittings, among others, are tailored to the customer’s specifications. Please contact the AMS Technologies thermal management experts to discuss your customized finned tube condenser or evaporator solution that exactly matches your requirements. Key Features: Tube Diameter: 5 mm, Much Lighter and Leaner Compared With the 3/8” Pattern Low Space Requirement: Significantly Smaller Housings, Can Fit into Almost Any Small Area Less Ice Build-up Low Weight: Lightest Coil Currently Available Coolant Saving: Requires Less Coolant Than 3/8” Pipes Low Cost: Saves on Operating Expenses Good for the Environment: Less Coolant, Raw Materials and Energy Tube Materials: Copper, Aluminium Tube Matrix: 19.05 mm x 12.70 mm Tube Pitch: Staggered Shape Options: Round Shape, Single Bend, Double Bends, Triple Bends Fin Shape: Corrugated, Sine Wave, Flat Fin Edge: Rippled, Straight Fin Density / Spacing: 7 fpi to 21 fpi (Fins per Inch) / 1.2 mm to 3.6 mm Fin Densities With or Without Special Coatings Available to Suit Any Climate. Applications: The Lord FiVe coil is suitable for refrigerant applications and can be customized to operate with a range of specialized heavy-duty, precision cooling or industrial cooling (gas coils) applications – Electronic & Computer Components; MRI; CAT Scans; Military Sensitive Technology; Refrigeration Units; Heat Pumps; Automotive Condensers; Trucks; Refrigerated Containers; Marine Condensers & Evaporators; Heavy Mining Equipment
