It holds 30 % contrast up to 185 lp\/mm on the sensor, about 16 lp\/mm on the part at 0.084x, so a camera with pixels of about 2.7 µm or finer records all the detail it passes (two pixels per line pair). An M160 filter thread takes a polarizer, band-pass or protective window.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSits between the 0.0838x and 0.085x versions of this series\u003c\/li\u003e\n\u003cli\u003eCovers sensors up to 2\/3\" (11.4 mm diagonal) without dark corners; a larger sensor would vignette\u003c\/li\u003e\n\u003cli\u003e0.1 % distortion: a corner point of the 140 mm field lands within about 67.9 µm of its true place\u003c\/li\u003e\n\u003cli\u003eTelecentricity under 0.1°: a 1 mm change in part height moves an edge by under about 1.7 µm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eLS-TCL-1901\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eObject field of view (dia. mm)\u003c\/th\u003e\n\u003ctd\u003e136\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMagnification (x)\u003c\/th\u003e\n\u003ctd\u003e0.084\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking distance (mm)\u003c\/th\u003e\n\u003ctd\u003e288±5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensor format\u003c\/th\u003e\n\u003ctd\u003e2\/3\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax sensor size (dia. mm)\u003c\/th\u003e\n\u003ctd\u003e11.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImage-side F\/#\u003c\/th\u003e\n\u003ctd\u003e4.9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImage-side MTF30 (lp\/mm)\u003c\/th\u003e\n\u003ctd\u003e\u0026gt;185\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTheoretical depth of field (mm)\u003c\/th\u003e\n\u003ctd\u003e±62.4@F11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImage-side distortion (% max)\u003c\/th\u003e\n\u003ctd\u003e\u0026lt;0.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eObject-side telecentricity (deg max)\u003c\/th\u003e\n\u003ctd\u003e\u0026lt;0.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eObject-to-image distance I\/O (mm)\u003c\/th\u003e\n\u003ctd\u003e659±5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal length TTL (mm)\u003c\/th\u003e\n\u003ctd\u003e354.6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount\u003c\/th\u003e\n\u003ctd\u003eC-mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNet weight (kg)\u003c\/th\u003e\n\u003ctd\u003e4.25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront filter thread\u003c\/th\u003e\n\u003ctd\u003eM160 P0.75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMeasured depth of field as shipped (mm)\u003c\/th\u003e\n\u003ctd\u003e15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShipping weight (estimated)\u003c\/th\u003e\n\u003ctd\u003e6.05 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cem\u003ePhoto shows a representative model of this series; see the specifications for this model.\u003c\/em\u003e\u003c\/p\u003e","brand":"LumaSpec Vision","offers":[{"title":"Default Title","offer_id":53079988764954,"sku":"LS-TCL-1901","price":3989.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1018\/5434\/7546\/files\/ls-tcl-1901-drawing-1.webp?v=1792789840"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1018\/5434\/7546\/collections\/20191217145058355835_9674aa55-ffec-4fc9-a029-396fa1024ab7.webp?v=1792763551","url":"https:\/\/lumaspecvision.com\/collections\/2-3-inch-telecentric-lenses.oembed?page=7","provider":"LumaSpec Vision","version":"1.0","type":"link"}
