Christie requires it on specific long-throw lenses, namely the 2.71-3.89:1 and 3.89-5.43:1 high-brightness and ultra-high-contrast zooms on the Griffyn 4K50-RGB, the 4.98-7.69:1 zoom on the Griffyn 4K35-RGB and Sapphire 4K40-RGBH, and the 4.1-6.9:1 zoom on the M 4K15 and M 4K25 RGB. The hood is part of keeping those lens and projector combinations within the Class 1, Risk Group 3 laser classification.\u003c\/p\u003e\u003ch2\u003eWhat does the Christie 163-168106-01 lens hood do?\u003c\/h2\u003e\u003cp\u003eChristie classifies its high-brightness RGB laser projectors by laser class and risk group, and with certain long-throw lenses it specifies a lens hood extension so the system meets Class 1, Risk Group 3. The 185 mm hood is the length Christie assigns to the lenses listed below.\u003c\/p\u003e\u003cp\u003eThe hood slides over the projection lens until it meets the shoulder stop and is secured by tightening a gear clamp screw. A lens clamp on the hood has two positions to suit different lens diameters, and Christie's instruction sheet lists which position each lens uses.\u003c\/p\u003e\u003cp\u003eThe hood has a tether. Christie instructs installers to attach the loose end of the tether to a secure structure and leave slack in it, which matters on flown and rigged projectors.\u003c\/p\u003e\u003cp\u003eBecause the requirement is lens- and projector-specific, check the lens part number against the table before ordering. Creation Networks confirms these requirements during projection design for systems built around projectors such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/christie-griffyn-4k35-rgb-36-500-lumens-native-4k-3dlp-rgb-pure-laser-projector\"\u003eChristie Griffyn 4K35-RGB\u003c\/a\u003e and \u003ca href=\"https:\/\/creationnetworks.net\/products\/christie-m-4k25-rgb-pure-laser-projector-compact-and-quiet-rugged-and-reliable-25-000-lumens-uhd-4k\"\u003eChristie M 4K25 RGB\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhat are the key features of the Christie 163-168106-01?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e185 mm extension\u003c\/strong\u003e — Matches the hood length Christie specifies for the listed long-throw lenses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaser classification support\u003c\/strong\u003e — Required to keep listed lens and projector pairs within Class 1, Risk Group 3.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-position lens clamp\u003c\/strong\u003e — Accommodates the different diameters of the compatible projection lenses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGear clamp mounting\u003c\/strong\u003e — Tightens around the lens to hold the hood securely in place.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety tether\u003c\/strong\u003e — Lets installers secure the hood to the structure on rigged projectors.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is the Christie 163-168106-01 typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAuditorium\u003c\/li\u003e\n\u003cli\u003eHouse of worship\u003c\/li\u003e\n\u003cli\u003eBroadcast studio\u003c\/li\u003e\n\u003cli\u003eMulti-purpose room\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto;\"\u003e\u003ctable style=\"width:100%;max-width:100%;min-width:300px;table-layout:fixed;border-collapse:collapse;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:40%\"\u003e\n\u003ccol style=\"width:60%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003ePart number\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e163-168106-01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eHood length\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e185 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eProjector families\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eChristie M RGB Series, Griffyn Series, Sapphire 4K40-RGBH (per lens)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eLens: 2.71-3.89:1 HB (144-107109-XX)\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eGriffyn 4K50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eLens: 3.89-5.43:1 HB (144-108100-XX)\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eGriffyn 4K50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eLens: 2.71-3.89:1 UHC (163-121105-XX)\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eGriffyn 4K50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eLens: 3.89-5.43:1 UHC (163-122106-XX)\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eGriffyn 4K50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eLens: 4.98-7.69:1 HB (144-109101-XX)\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eGriffyn 4K35, Sapphire 4K40-RGBH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eLens: 4.1-6.9:1 (118-100115-XX)\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eM 4K15, M 4K25 RGB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:6px;text-align:left\"\u003eMounting\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eGear clamp with two-position lens clamp; tether\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eIs the lens hood required or optional?\u003c\/h3\u003e\u003cp\u003eIt is required for the listed lens and projector combinations to meet Class 1, Risk Group 3.
