NOA 68 Optical Adhesive 1oz bottle

Refractive Index: 1.56; 300 cps Viscosity at 25°CNOA 61 strong, heat resistant optical adhesive with refractive index 1.56 and curing between 320 - 380 nm UV light MIL-A-3920 compliant (10g syringe)

Refractive Index 1.56; 2000 cps Viscosity at 25°C Norland Optical Adhesive 63 ("NOA63") is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light. Since it is a one part system and 100% solids,it offers many advantages in bonding of optical elements where the bonding surface can be exposed to light. The use of NOA 63 eliminates premixing, drying or heat curingoperations common to other optical adhesive systems. Curing time is remarkably fast, and is dependent upon the thickness applied and the amount of ultraviolet light energy available.NOA 63 is recommended for the bonding of achromats, prisms and all other precision compound optics. The outstanding characteristics of the adhesive are its low fluorescence and its excellent transmission in the near UV range. After fullcure, the adhesive has good transmission from 320 to 3,000 nanometers.Typical Properties of NOA 63 Solids 100% Elongation at Failure 6% Modulus of Elasticity (psi) 240,000 Tensile Strength (psi) 5,000 Hardness - Shore D 90 Shelf life of the liquid is at least 6 months from the date of shipment if stored in a cool  (5-22° C), dark place in the original container. If refrigerated, allow the adhesive to come to room temperature prior to use.

Single and Dual Source; 633-1625 nm; Reflectance Dynamic Range -1--70 dB; Fiber Type SM, MM; 8° Angled NTT-FC/APC Receptacle OZ Optics’ BM series of backreflection meters measure the total accumulated optical return loss that is reflected back through a device or fiber under test. The measured reflections are caused by Rayleigh scattering, sudden changes in the refractive index within the device under test (DUT), or from connector ends. BM series meters are available as portable handheld devices (BM-100 and BM-200) or in a benchtop form factor (BM-1000 and BM-2000). The BM series backreflection meters are configured with an FC/APC connector on the output port, to minimize unwanted reflections. The meters have either one or two built-in laser diodes (plus a choice of SLEDs or LEDs for benchtop models) for return loss measurement at specific wavelengths. An optional detector can be added to the unit for insertion loss measurements. Reference patchcords for calibration are available. BM series meters cover a wide range of available wavelengths, thus providing measurement  capabilities for non-telecom applications as well as telecom. BM-100/200 portable meters' wavelengths range from 8050 nm to 1625 nm, while the BM-1000/2000 benchtop meters are offered with special wavelengths, ranging from 633 nm to 1625 nm. The BM-1000/2000 benchtop backreflection meters feature a colour touchscreen display with a simple graphical user interface. The units come with a built-in memory that allows the user to store measured DUT test results. The BM series backreflection meters can be operated remotely via the built-in USB interface. A universal AC/DC power supply is included with all units. Reference patch cords for calibration are available. Adapter patch cords are also available, to allow the meter to be used with devices having different connectors.

 Refractive Index 1.56; 200 cps Viscosity at 25°C Norland Optical Adhesive 71 ("NOA71") is an optically clear, liquid adhesive that will cure when exposed to long wavelength ultraviolet light (10g syringe). The adhesive is a one-part, 100% solids material that offers advantages in bonding applications that require optical clarity or require fast cure times and long term stability over a wide range of temperatures. The use of NOA 71 eliminates premixing, drying, or heat curing operations common to other adhesive systems.NOA 71 was formulated to provide a strong bond to glass surfaces. This adhesive can also be used for adhering to other substrates, such as metal, fiber- glass, and glass filled plastics. Typical applications are laminating solar cells, holographic plates, flat panel displays and touch screens or as a clear coating on plastic or metal.NOA 71 is cured with long wavelength UV light from 315 to 400 nanometers with peak absorption at 365 nm. The amount of energy required for full cure is 3.5 Joules/sq. cm of UV light. Typical Properties of NOA 71 Solids 100% Elongation at Failure 43% Modulus of Elasticity (psi) 55,000 Tensile Strength (psi) 1,300 Hardness - Shore D 86 Dielectric Constant (1 MHz) 4.0 Dielectric Strength (V/mil) 456 The shelf life of NOA 71 liquid is at least 4 months from the date of shipment if kept in a cool (5-22° C), dark place in the original container. If refrigerated, allow the adhesive to come to room temperature prior to use.

Ridge Waveguide Fabry-Perot Laser Diodes; 808-1060 nm; Spectral Width 0.3-3 nm; Output Power 100-800 mW; Threshold Current ≤70-300 mA; Slope Efficiency 0.8, 0.9 W/A; Forward Current 170 to 1,500 mAToptica eagleyard’s RWL series of Fabry-Perot ridge waveguide laser (RWL) diodes operate on a single transverse resonator mode. This leads to high power output (100 up to 800 mW in cw mode) with diffraction limited beam profile. However, multiple axial (longitudinal) modes may occur which can lead to differing optical frequencies. The frequencies are separated by the free spectral range of the resonator given by the reflecting facets of the laser chip.Additional features such as collimation optics for optimum beam quality or a thermoelectric cooling module for more stable frequency performance can be integrated in the package on request. Direct temperature control of the chip enables optimum wavelength stability and better heat dissipation under continuous high-power operation.Key Features:Fabry-Perot Edge-emitting Ridge Waveguide Laser DiodesBroad Wavelength Range: 808 to 1060 nmTyp.
