Christie 163-168106-01 – 185 mm Lens Hood Extension

What is the Christie 163-168106-01 185 mm lens hood?

The Christie 163-168106-01 is a 185 mm lens hood extension for Christie Enterprise RGB laser projectors. 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.

What does the Christie 163-168106-01 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 185 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.

Because 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 Christie Griffyn 4K35-RGB and Christie M 4K25 RGB.

Which lenses need this hood?

See the specification table. The requirement is specific to each lens and projector pair, so 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.

Do I need a hood for short-throw lenses?

Christie's hood table only lists the long-throw zooms shown above. Other lenses do not appear on the list.

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.
