OP-740x air spaced etalons are available in eight sizes with diameters from 25.4 (1”) to 203.2 mm (8”) and apertures from 5 to 150 mm. Wavelength range, finesse, free spectral range (FSR) and design details can be realized based on customer requirements. Etalons are optically transparent, flat components with very precisely parallel reflecting surfaces. While solid etalons consist of solid plates of optical material, air spaced etalons are formed by two mirrors with an air gap between them. One major issue with solid etalons is their instability to temperature changes, which can be unacceptable in certain applications. Air spaced etalons reduce this problem of temperature dependence by using air as the etalon medium to greatly reduce the change in refractive index with temperature. The mirror spacing is now determined by spacers that may still be made from Fused Silica or from even more stable materials such as ULE or Zerodur. Due to their construction, air spaced etalons are significantly more complex since there are now three components involved (two end mirrors and the spacer). The outside surfaces of the end mirrors also need to be wedged and AR-coated to avoid reflections from these surfaces causing additional unwanted etalon effects. Sometimes you need something special – if you are looking for a customized air spaced etalon that exactly meets your specific requirements, please get in touch with the AMS Technologies etalon experts. Our supplier LightMachinery is extremely experienced with specifying, designing and manufacturing custom etalons using the company’s patented fluid jet polishing (FJP) technology. We are looking forward to discussing your customized etalon solution! Fluid jet polishing (FJP) systems use a fine stream of slurry to accurately remove nanometers of material from an optical surface. Many years of refining this computer controlled polishing technology have enabled LightMachinery to use FJP for the adjustment of the shape and flatness of optical components such as etalon mirrors to within a few nanometers as well as the production of very thin components such as wafers and thin etalons that are impossible to accurately polish using conventional technology.

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.
