It holds 30 % contrast up to 120 lp\/mm on the sensor, about 17 lp\/mm on the part at 0.141x, so a camera with pixels of about 4.2 µm or finer records all the detail it passes (two pixels per line pair). An M204 filter thread takes a polarizer, band-pass or protective window.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e0.141x at 318 mm: a 4\/3\" sensor sees a field about 153 mm across (diagonal)\u003c\/li\u003e\n\u003cli\u003eSits between the 0.14x and 0.1411x versions of this series\u003c\/li\u003e\n\u003cli\u003eCovers sensors up to 4\/3\" (24 mm diagonal) without dark corners; a larger sensor would vignette\u003c\/li\u003e\n\u003cli\u003e0.1 % distortion: a corner point of the 170 mm field lands within about 85.1 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-1710\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eObject field of view (dia. mm)\u003c\/th\u003e\n\u003ctd\u003e170\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMagnification (x)\u003c\/th\u003e\n\u003ctd\u003e0.141\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWorking distance (mm)\u003c\/th\u003e\n\u003ctd\u003e318±5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensor format\u003c\/th\u003e\n\u003ctd\u003e4\/3\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax sensor size (dia. mm)\u003c\/th\u003e\n\u003ctd\u003e24\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImage-side F\/#\u003c\/th\u003e\n\u003ctd\u003e7.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImage-side MTF30 (lp\/mm)\u003c\/th\u003e\n\u003ctd\u003e\u0026gt;120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTheoretical depth of field (mm)\u003c\/th\u003e\n\u003ctd\u003e±32.2@F16\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\u003e776±5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal length TTL (mm)\u003c\/th\u003e\n\u003ctd\u003e446.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount\u003c\/th\u003e\n\u003ctd\u003eM58\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNet weight (kg)\u003c\/th\u003e\n\u003ctd\u003e7\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront filter thread\u003c\/th\u003e\n\u003ctd\u003eM204 P0.75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShipping weight (estimated)\u003c\/th\u003e\n\u003ctd\u003e9.90 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":53079989846298,"sku":"LS-TCL-1710","price":4829.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1018\/5434\/7546\/files\/ls-tcl-1710-drawing-1.webp?v=1792789793"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1018\/5434\/7546\/collections\/20191217145058355835_ff8b3197-c0a8-497d-81b0-7c32f9b9cc85.webp?v=1792763546","url":"https:\/\/lumaspecvision.com\/collections\/4-3-inch-telecentric-lenses.oembed?page=6","provider":"LumaSpec Vision","version":"1.0","type":"link"}
