Christie 163-167105-01 – 410 mm Lens Hood Extension

What is the Christie 163-167105-01 410 mm lens hood?

The Christie 163-167105-01 is a 410 mm lens hood extension for Christie Enterprise RGB laser projectors. Christie requires it on the longest-throw zooms: the 4.98-7.69:1 high-brightness zoom on the Griffyn 4K50-RGB and the 6.9-10.4:1 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.

What does the Christie 163-167105-01 lens hood do?

Christie 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 410 mm hood is the length Christie assigns to the lenses listed below.

The 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.

The 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.

Note that the same 4.98-7.69:1 lens takes the shorter 185 mm hood (163-168106-XX) on the Griffyn 4K35-RGB and Sapphire 4K40-RGBH, so the hood depends on the projector as well as the lens. Creation Networks confirms these requirements during projection design for systems built around projectors such as the Christie Griffyn 4K35-RGB and Christie M 4K25 RGB.

Frequently Asked Questions

Is the lens hood required or optional?

It is required for the listed lens and projector combinations to meet Class 1, Risk Group 3. Christie notes hoods are not required when the M 4K25 RGB and M 4K+25 RGB run in low line mode.

Which lenses need this hood?

The 4.98-7.69:1 HB zoom on the Griffyn 4K50-RGB and the 6.9-10.4:1 zoom on the M 4K15 and M 4K25 RGB. Confirm your lens part number before ordering.

How is the hood installed?

Set the lens clamp position, slide the hood over the lens to the shoulder stop, tighten the gear clamp, then attach the tether to a secure structure with some slack.

Why does the same lens need different hoods on different projectors?

Christie assigns hood length by lens and projector pair. The 4.98-7.69:1 lens takes the 410 mm hood on the Griffyn 4K50-RGB but the 185 mm hood on the Griffyn 4K35-RGB and Sapphire 4K40-RGBH.

Can Creation Networks confirm compatibility?

Yes. We check lens, hood and projector combinations as part of projection design and installation. Browse Christie projector lenses or the full Christie Digital collection.
