00:00Your laser's cutting ragged edges and you're about to drop real money on a new ZNSE lens?
00:05Hold up.
00:06For this video, ZNSE lens vs lens tube, which is clearer, I dug up 5 cheap parts that fixed
00:12my beam, and I found the best deals on every single one.
00:16First up, this 24x25mm autofocus Z-axis lens tube.
00:21The killer feature?
00:23It handles focus for you, the Z-axis adjusts on the fly, so no more shimming your lens
00:28up and down every time you switch materials.
00:31$14, nearly 5,000 sold, perfect 5-star rating.
00:35If your machine doesn't autofocus yet, this is the cheapest upgrade that actually changes
00:40how you work.
00:42Next, this 25mm laser head lens tube with the 20mm air nozzle.
00:47Best part is the choice, for focal lengths, 38.1 up to 101.6, so you can tune it for
00:54fine
00:54engraving or deep cutting.
00:56And it's $4.65.
00:58That's cheaper than lunch.
01:01Over 4,500 buyers, 4.9 stars.
01:05Grab one as a spare, every workshop should have a backup head.
01:09Then we've got the Hunst lens tube.
01:1225mm outer diameter, takes a 20mm lens, 3 focal lengths, 50.8, 63.5, and 101.6.
01:21What sold me is the fit, it seats the lens dead center, keeps that ZNSE spot clean, no tilted
01:26beam weirdness.
01:28$6.84, 3,000 sold, straight 5 stars.
01:33Solid pick from a brand laser people actually trust.
01:36Number 4 is the QDHW OELC series.
01:4124mm outer diameter for 20mm lenses and that 24mm size matters, because some heads need the
01:48slimmer fit when a standard 25 won't slide in.
01:521178, 2800 sold, 5 stars.
01:55If a regular tube never sits right in your machine, this is the one that will.
02:00Last up, the CloudRay E-series extension ring.
02:04This one's clever, it's not a whole tube, it's an extension that adds length for longer focal
02:09lengths, your 63.5 or 127mm lenses, while keeping the 25mm outer diameter.
02:17696, 2500 sold, 5 stars.
02:21Cheapest way to run a long focus lens without buying a whole new head.
