VXP Variable Optical Attenuators

UV-NIR; 200-1750 nm; Resolution 0.05-50.0 nm; Sensitivity 38,000-665,000 Counts/µW per ms Integration Time; CMOS or InGaAs Array Detector; Interface USB 2.0; 95x68x20 mm Miniature spectroscopy redefined – that's what Avantes considers the CompactLine series spectrometers. The new generation, Avantes’ AvaSpec-Mini MK-II series (AvaSpec-Mini2048CL and AvaSpec-Mini4096CL) is definitely one of the smallest types of spectrometers on the market today. In cases where size matters, the AvaSpec CompactLine family offers spectrometers with the smallest form factor – only the size of a deck of cards. This enables easier integration of Avantes’ spectrometers into machines and handheld devices. Squeezing down the size hardly compromises the performance of the instruments but limits the customer a bit in the number of possible configurations. This instrument with excellent temperature and wavelength stability is easy to take anywhere you like and very well suited for handheld applications. The AvaSpec-Mini-CL series with CMOS detectors and advanced electronics and communications can be equipped with a 2048-pixel CMOS detector (AvaSpec-Mini2048CL) or Avantes’ first-to-the-market 4096-pixel array (AvaSpec-Mini4096CL). And the AvaSpec-Mini-NIR is a compact near-infrared spectrometer with InGaAs detector, based on Avantes’ popular AvaSpec-NIR256-1.7-EVO NIRLine series spectrometer. Enjoy the speed and enhanced native UV/NIR response of CMOS with an incredible resolution of up to 0.09 nm unavailable anywhere else. The low stray light design allows stray light levels from as low as 0.2% and the fast response time boasts data transfer speeds as fast as 4.6 ms/scan and integration times ranging from 30 to 50 s. Customization is possible when adequate volumes are needed. This makes the CompactLine especially suited for OEM users wanting to integrate a spectrometer into their own devices. To learn more about all the available options and to find the perfect setup that matches your needs, please contact AMS Technologies to discuss your wishes with our sales engineers. The possibilities are virtually endless! For customers with urgent needs and general flexibility in their specifications, Avantes keeps a variety of preconfigured AvaSpec-Mini-CL series CompactLine spectrometers in stock so they are readily available within a significantly decreased shipping time. All preconfigured spectrometers are available at discount pricing (as opposed to custom models) and include an upgrade to AvaSoft-Full.

Sercalo Microtechnology's VXA series of miniature MEMS variable optical attenuators (VOAs) has been discuntinued by the supplier. For replacement and new projects, please refer to the mVOA series of ultra-small or VXP1 series of miniature MEMS variable optical attenuators (VOAs). MEMS-based, Pigtail Style, Transmission Mode; Single/Dual Types; Fiber Type SMF28; 1240 to 1640 nm; Attenuation up to 30 dB Sercalo Microtechnology's VXA series of miniature MEMS variable optical attenuators (VOAs) is ideal for fiber optic communication systems and submodules. The non-latching attenuators work in transmission mode and allow for the continuous adjustment of the attenuation with a 0 to 5 V control voltage. The highly reliable attenuation mechanism is based on a micromechanical shutter – a silicon MEMS chip, on which a mirror can be moved in and out of the optical path by electrostatic actuation – and features below 2 ms response time and below 1 dB insertion loss. The VXA variable optical attenuators are composed of an optical subsystem and an electrical driver interface. VXA series is available in single (VXA1) and dual (VXA2) variants and normally open or normally closed designs. The plastic package is one of the smallest in the industry and optimized for low cost production while maintaining high reliability comparable to a solid-state device. The component is designed to meet Telcordia 1221 quality standards. The standard VXA attenuator achieves minimum insertion loss at 0 V input voltage. The VXAxOF variant is normally closed, i.e. at 0 V the attenuation is maximum and is reduced with increasing input voltage. Key Features: Small Size (23 x 10 x 6 mm) Low PDL Very Fast 0 to 5 V Control Single or Dual Channel Applications: Power Management in DWDM Transceivers; Amplifier Gain Control; Optical Subsystems; Array Integration
