The PMA integrates a fast Photomultiplier Tube (PMT), a high voltage power supply and a pre-amplifier. Thermoelectric cooling and automatic overload protection are available as an option.<\/p>\n<p><strong>Housing with dedicated RF and magnetic shielding<\/strong><\/p>\n<p>These devices are built in an iron or nickel coated aluminum housing with titanium nitride or gold refinement to achieve high level of RF and magnetic shielding and protection against interference with other devices. The built in pre-amplifier is specially targeted at timing sensitive applications such as Time-Correlated Single Photon Counting\u00a0(TCSPC). Signal output for all models is a standard 50\u00a0Ohms SMA connector.<\/p>\n<p><strong>Spectral ranges between 185\u00a0nm and 920\u00a0nm<\/strong><\/p>\n<p><a title=\"Quantum effciency of the PMA Series\" href=\"https:\/\/www.picoquant.com\/?ACT=32&amp;f=spectra_pma1g.jpg&amp;fid=27&amp;d=7308\" data-fancy-group=\"image-group\" data-fancybox-group=\"image-group0\"><img decoding=\"async\" class=\"ci-right ci-image perc30 with-border\" src=\"https:\/\/www.picoquant.com\/images\/uploads\/product_images\/7308\/spectra_pma1g__small.jpg\" alt=\"Detection effciency of the PMA Series\" \/><\/a><\/p>\n<p>Various photocathodes can be incorporated into the PMA to meet the user&#8217;s needs. Three different cathode versions are available. A blue sensitive, low dark count version with very high quantum efficiency up to 40% covers the spectral range from 230 nm to 700\u00a0nm. The standard unit is sensitive in the range from 185\u00a0nm to 820\u00a0nm and features a quantum efficiency up to 20%. An extended red sensitive cathode covers the 230 nm to 920\u00a0nm range with a quantum efficiency up to 20%. A thermoelectrically cooled housing is available to reduce the dark count rate (recommended for red sensitive versions).<\/p>\n<p><strong>Integrated shutter, overload detection<\/strong><\/p>\n<p>The housing is available in three different versions. The OEM design contains no safety shutter. Standard PMA-M features a security shutter, which can be interlocked with e.g. a\u00a0sample chamber lid. Cooled versions (PMA-C Series) incorporate in addition an automatic overload detection function that closes the shutter in case of over-illumination. All modules needs a 12\u00a0V\u00a0DC supply line, which is delivered with the PMA-M and PMA-C versions.<\/p>\n<p><strong>Applications<\/strong><\/p>\n<p>The single photon sensitive detectors of the PMA Series can be used in various applications, where the large active area, good sensitivity and good timing resolution of the detector are important, such as:<\/p>\n<ul>\n<li>Time-Resolved Fluorescence<\/li>\n<li>Fluorescence Lifetime Imaging (FLIM)<\/li>\n<li>Phosphorescence Lifetime Imaging (PLIM)<\/li>\n<li>Foerster Resonance Energy Transfer (FRET)<\/li>\n<li>Fluorescence Anisotropy (Polarization)<\/li>\n<li>Time-Resolved Photoluminescence (TRPL)<\/li>\n<li>TRPL Imaging<\/li>\n<li>Lanthanide Upconversion<\/li>\n<li>Bunch Purity<\/li>\n<li>LIDAR\/Ranging\/SLR<\/li>\n<li>Diffuse Optical Tomography and Imaging<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>We offer a range of PMA series photon detectors, The PMA detector is a single photon sensitive, fully integrated, fast time response and low noise photon sensor that covers a wavelength range 230-700nm.<\/p>\n","protected":false},"featured_media":50337,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_brand":[],"product_cat":[236],"product_tag":[],"class_list":{"0":"post-50317","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-photon-counting-and-timing","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.6 (Yoast SEO v27.7) -
