What this page is
buythis.co.za/laser-machine-consumables is the laser consumables section of Buythis, AM.CO.ZA's online shop. On the live page it is only a heading, a link to laser accessory videos and tiles to mirrors and lenses, CO2 laser tubes, fiber cutter consumables, marker consumables, laser machines and cooling equipment. This knowledge base page explains which laser parts wear out and need replacing, and lists the main consumables currently on Buythis with their prices (118 products in total, counting every nozzle size).
Which laser parts are consumables
- CO2 laser cutters and engravers (TruCUT range) send the beam from a sealed glass laser tube over three reflecting mirrors to a focus lens in the laser head. The lens and mirrors get dirty from smoke and need regular cleaning and eventual replacement, and the glass tube loses power over its working life and is replaced as a whole. The nozzle under the head directs air assist onto the cut.
- Fiber laser cutters (RayCUT range) carry the beam through a fiber cable into a cutting head (Raytools or BOCI). Inside the head a collimator lens and a focus lens shape the beam, and protective windows above and below the lenses take the smoke and spatter so the lenses stay clean. The copper nozzle at the tip wears and is replaced often, in the bore size that suits the material and thickness.
- Fiber laser markers (LabelMark range) use an F-theta field lens under the galvo scan head. The lens sets the marking area: a smaller field gives a finer, more concentrated spot and a larger field covers more area.

25mm ZnSe focus lens, 50.8mm focal length | Φ25mm ZnSe Lens Focal Length 50.8mm with AR/AR Coating | R 726.80 |
Buythis also lists more 15mm, 18mm, 19mm and 25mm ZnSe lenses, with focal lengths between 38.1mm and 63.5mm. Several lens listings point to a more durable "P" version of the same lens for heavy use. Match the lens diameter to the lens holder in your laser head and the focal length to the job: a shorter focal length gives a smaller spot for fine engraving, and a longer focal length keeps the beam focused through thicker material.

Prices are current Buythis prices including VAT from the product dump dated 2026-10-20. Some prices come from slightly older dump entries (2026-10-17, 2026-10-18, 2026-10-19). Check the product page before ordering, since prices change.
How to choose
- Know your machine. CO2 lasers (TruCUT) use ZnSe or germanium lenses, reflecting mirrors and glass tubes. Fiber laser cutters (RayCUT) use nozzles, protective windows and lens housings made for their Raytools or BOCI cutting head. Fiber markers (LabelMark) use F-theta lenses with an M85x1 thread.
- Measure before ordering a lens. Check the diameter and focal length of the lens in your machine; the videos below show how to measure them.
- Keep spares of the parts that wear fastest. On a fiber cutter that means nozzles in the sizes you cut most and lower protective windows (sold singly and in packs of 10). On a CO2 laser keep a spare focus lens, a mirror and cleaning wipes.
- Clean, then replace. Clean optics with
L-OPTICAL/WIPEfirst; replace a lens, mirror or window when it is cracked, burnt or still dirty after cleaning, and realign the mirrors after replacing them or the tube.
