The design of these photodiodes is such that their long-wave response (i.e. >900 nm) has been enhanced without introducing any undesirable properties.The C30954EH, C30955EH and C30956EH long-wavelength enhanced APDs have quantum efficiency of up to 40 % at 1060 nm. 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.The C30954EH long-wavelength enhanced silicon avalanche photodiode (Si APD) provides a 0.8 mm active area diameter in a TO-5 package.The C30955EH long-wavelength enhanced silicon avalanche photodiode (Si APD) provides a 1.5 mm active area diameter in a TO-5 package.The C30956EH large-area, long-wavelength enhanced silicon avalanche Photodiode (Si APD) provides a 3 mm active area diameter in a TO-8 package.Key Features:Active Area Diameter: 0.8, 1.5, 3 mmHigh Quantum Efficiency at 1060 nm: ≤40%Enhanced Long-wave Response: >900 nmFast Response Time: 2 nsWide Operating Temperature RangeLow Capacitance @100 kHz: 2 to 10 pFResponsivity @1060 nm: 25 to 36 A/WDark Current: 50, 100 nASpectral Noise Current: 0.5 pA/√HzNEP @1060 nm: 14 to 20 fW/√HzVop Range: 275 to 425 VHermetically Sealed Packages: TO-5, TO-8RoHS CompliantTEC Option AvailableCustomization Available Upon RequestApplications: Range Finding; LiDAR (Light Detection and Ranging); YAG Laser DetectionPlease note that Excelitas products are available from us only in Denmark, Finland, Iceland, Norway, and Sweden. 

1 Channel; Dynamic Range >15 dB; Wavelength 780 nm; Spatial Resolution 10 cm; Measurement Range 250 m; Temperature Accuracy 1.5 °C; Optical Fiber Connectors E-2000 APC, Other Luciol Instruments’ LDT-100 high-resolution distributed optical temperature sensor measures the temperature profile across standard optical fibers. The measurement technique is based on Raman scattering. Due to the temperature dependence of the Raman scattering signal (Anti-Stokes), temperature variations along the sensing optical fiber are transformed in a variation of the backscattered signal. The LDT-100 uses photon-counting technology to achieve a high detection efficiency and very high spatial resolution. An internal temperature calibration reference makes the system ready for testing and minimizes time consuming user re-calibration. The LDT-100 also integrates OTDR testing capability which allows integrity and condition testing of the sensing optical fiber. The LDT-100 is a fully portable, simple and easy-to-use instrument, with user-friendly GUI software. A desktop version with USB interface is available as an option.
