Christie requires it when the Griffyn 4K50-RGB uses the 1.95-3.26:1 zoom lens, in either the high-brightness or ultra-high-contrast version. The hood is part of keeping that lens and projector combination within the Class 1, Risk Group 3 laser classification.\u003c\/p\u003e\u003ch2\u003eWhat does the Christie 163-170109-01 lens hood do?\u003c\/h2\u003e\u003cp\u003eChristie classifies its high-brightness RGB laser projectors by laser class and risk group, and with certain lenses it specifies a lens hood extension so the system meets Class 1, Risk Group 3. The 30 mm hood is the length Christie assigns to the 1.95-3.26:1 zoom on the Griffyn 4K50-RGB.\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\u003eLonger Griffyn 4K50-RGB zooms take the 185 mm or 410 mm hoods instead, so check the lens part number before ordering. Creation Networks confirms these requirements during projection design for Griffyn systems, including the related \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.
