APD Silicon Avalanche Photodiodes

Fiber 8-1000 µm; Standard Length 2 or 1 m; SMA terminatorsAvantes provides a diverse selection of fiber-optic cables, available in various lengths and configurations to suit your specific needs.Fiber-Optic CablesAvantes offers a wide range of fiber-optic cables, which can be manufactured in different lengths and configurations to meet your requirements. For most applications, a 2-meter length is sufficient, making it our standard fiber length.Avantes provides SMA-905 or FC/PC connectors, which can be the same or different on both ends. For certain applications, special round-to-linear fiber cables are recommended. These cables have a bundle of fibers arranged in a round pattern on one end and a linear array on the other. The linear array (typically 1mm in height) aligns with the spectrometer slit height, also 1mm, maximizing light throughput for high-sensitivity applications. Fiber-optic cable types and diameters are recommended based on the wavelength range and sensitivity required for a measurement. Generally, different fiber types are classified as follows: for the UV range, high OH UV/VIS fiber is used. For measurements below 240 nm in the UV, special high OH UV/VIS fiber called solarization-resistant fiber (SR) is available. For longer wavelengths, low OH VIS/NIR fiber is recommended. Our standard broadband fiber combines the performance of UV, UV-SR, and IR fibers, offering the best of both worlds.Depending on application requirements, Avantes offers various jacketing options, including Kevlar-reinforced PVC sleeving with PTFE inner tubing (Standard), heavy industrial chrome-plated brass mono-coil, stainless steel (BX), silicone-coated stainless steel mono-coil (MS), flexible chrome-plated brass outer jacket with hooked profile (ME), and other special jacketings upon request. For high-temperature applications, special high-temperature epoxy (HT) is available and should be specified at the time of order.Recommended wavelengths for different cables:200-2500 nm: UV/VIS/NIR (UVIR)UV/IR available in core sizes 100, 200,400, 600 μm200-800 nm: Solarization-resistant (-SR)250-800 nm: UV/VIS (UV)350-2500 nm: VIS/NIR (IR)Multi-Furcated Fiber-Optic CablesFor simultaneous multi-point measurements and use with Avantes multi-channel spectrometers, multi-furcated fiber-optic cables are essential. These assemblies can function as either a combiner or splitter of light, featuring multiple legs on one side that converge into a single connector on the opposite side. Avantes offers virtually any combination possible, tailored to meet your specific requirements.Typical setups that require multi-furcated cables are:Various types of connectors, jacketings, and fibre sizes are available for these multi-furcated fiber cables.

Users can specify various window sizes to meet desired fields-of-view. PYD DigiPyro dual-element pyrodetectors cover the advanced family of DigiPyros, including Excelitas’ low-power DigiPyros for battery-operated motion detection.Excelitas’ newly improved PYD 1788 and PYD 1798 dual-element DigiPyros are now re-engineered for improved energy efficiency of a mere 1.8 V at 5 µA power requirement, making them ideal motion detection sensors for extended service life in mobile and remote battery-operated devices. Both dual-element pyrodetectors feature two elements in series connection in TO-5 metal housing with optical window options.The PYD 1788 has the standard size window for economy and mid-range sensing, while PYD 1798 has an enlarged window enabling broader fields-of-view. The element configurations are identical, along with the internal electronic circuits. Both the PYD 1788 and PYD 1798 models include a built-in temperature diode which provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal, communicated in one digital bit stream of 2x14-bit output via a single wire “Direct Link” connection to a suitable host microprocessor.The PYD 1794 dual-element Digipyro PIR pyrodetector is the low-profile version of the DigiPyro family and features two elements in series connection in a low-profile TO-39 metal housing with optical window. An internal diode provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal.As the latest addition to Excelitas’ DigiPyro detector offering, the PYD 2792 dual-element PIR pyrodetector features two standard elements in parallel connection designed into a compact SMD (surface mount) housing with optical window. This design streamlines integration to the host system with significantly reduced form factor. An internal integrated circuitry converts the element signals into a 14 bit digital data output which can be viewed through the digital interface. And an internal diode provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal.The PYD 2592 is the low-power version of PYD 2792, with dual-element pyrodetectors in a compact SMD housing. The sensor includes a fully configurable motion detection unit with an interrupt feature to wake up a sleeping host system. This allows for lowest power consumptions and is therefore ideally suitable for battery operation in compact and mobile applications.An internal diode provides output related to the pyro’s internal temperature. This makes the output signal into a 14 +14 bit signal. With its reduced voltage requirements, this device is well suited for battery operation in compact and mobile applications.With a mere 1.8 V power supply voltage and significantly reduced supply current, Excelitas’ PYD 1588 and PYD 1598 are the first real low-power enhanced DigiPyro Pyrosensors. Both are fully integrated, dual-element detectors with two different window size options, offering added features and low-current power consumption for extended remote motion detection in battery operated devices.The power requirements of the system level can be further reduced with the wake-up/sleep feature of this detector series, which also promotes power efficiency and extends service life. PYD 1588 and PYD 1598 low-power DigiPyro pyrodetectors are ideal for prolonged battery-operated motion detection. A selectable band-pass function and pulse count option further compliment the full functionality of these devices.With a diameter of 4.7 mm, the PYD 5731 miniature, dual-element DigiPyro® pyrosensor is one of the smallest designs in the Excelitas pyrodetector portfolio. The PYD 5731 features two miniaturized elements in series connection in TO-46 metal case (4.7 mm dia. X 3.3 mm height) with optical window.The PYD 5731 offers the same Direct Link interface as the regular PYD 1798 DigPyro. The miniature housing, in conjunction with a reduced element size and spacing, enables customers to reduce the size of their optics and innovate more compact product designs.The PYD 2597 Ultra-Low Power DigiPyro sensor extends the DigiPyro Series with one of the lowest power PIR detectors currently available, optimized for battery-operated and remote motion detection systems. It operates at supply voltages as low as 1.4 V and consumes only about 2 µA at 1.8 V, enabling significantly extended service life in energy-constrained designs. The device integrates two fully RoHS-compliant pyroelectric elements with on-chip digitization and a configurable Motion Detection Unit that issues an interrupt on motion detection, allowing the host system to remain in deep sleep until needed. Its single-wire digital interface simplifies host integration while a 130° field-of-view and robust EMI immunity support reliable performance in electrically noisy environments. The PYD 2597 is particularly suited for long-range motion sensing, intrusion alarms, energy-saving controls, horizontal mounting applications and other battery-powered PIR use cases where ultra-low power consumption and compact integration are priorities.Applications: Long-distance Motion Detection (With Lens); Energy Saving Applications; Intrusion Alarms; Horizontal Mounting Applications; Battery OperationPlease note that Excelitas products are available from us only in Denmark, Finland, Iceland, Norway, and Sweden.
