It consists of an array of 23 single photon avalanche detectors (SPAD) with high native fill factor and microlenses (effective fill factor &gt; 80%), high photon detection and low timing jitter.<\/p>\n<p><strong>Optimisation for low dark count applications<\/strong><br \/>\nThe detector array consists of SPADs with low dark count rates of typ. 100 cps, with typically only 1 hot pixel with &gt; 1 kcps. In the PDA-23 these dark count rates are further reduced via an integrated Peltier-cooler.<\/p>\n<p><strong>Versatile mounting options<\/strong><br \/>\nThe PDA-23 detector has a C mount in front of the sensor and mounts for optical tables for easier integration into optical set-ups. Customisation for other mounting requirements is possible.<\/p>\n<p><strong>Available as add-on for MultiHarp 160 event timer<\/strong><br \/>\nThe PDA-23 is available as a detector add-on for the MultiHarp 160. It has a break-out adaptor box with 23 SMA output connectors included, which provide the output signals from each individual SPAD of the array.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cooled Single Photon Detector Array Peltier-cooled array detector with 23 densely packed single photon avalanche diodes Large effective fill factor High photon [&hellip;]<\/p>\n","protected":false},"featured_media":50303,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_brand":[],"product_cat":[236],"product_tag":[],"class_list":{"0":"post-50258","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) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Cooled Single Photon Detector Array - Laser 2000<\/title>\n<meta name=\"description\" content=\"Cooled Single Photon Detector Array.
