Original Raytools protective window in the 24.8 × 1.5 mm size - the collimation-side optic that guards the collimating lens inside the sealed upper section of a fiber laser cutting head. AR-coated on both faces for 1064-1080 nm with over 99% transmittance, and dimensioned for 4 kW-class Raytools heads with drawer-type holders. Unlike the focusing-side window below it, this one is not a weekly consumable: in a healthy head it stays clean for months, and a dirty one means contamination has found a way inside. GST invoice on every order, with bulk rates for workshops, service engineers and dealers.
The Raytools Original Protective Lens D24.8 x 1.5mm is a genuine Raytools fused-silica protective window sized at 24.8mm diameter x 1.5mm thickness, built for the collimation side of Raytools fiber laser cutting heads rated up to 4kW. It shields the internal collimating lens from spatter, smoke and dust, forming a low-cost sacrificial barrier that keeps beam quality stable during daily cutting.
Raytools is a well-known fiber laser cutting head brand, and this 24.8 x 1.5mm window sits in the same standard collimation-lens size family used on Raytools heads such as the BM109, BM111 and BT-series (Raytools lists a closely related 24.9 x 1.5mm collimation window across its documentation). As a genuine Raytools part, it is made to the manufacturer's own tolerance for a flush, correct seat in the collimation-lens holder, rather than an approximate aftermarket fit. Like any protective window, it is a routine, sacrificial consumable and should be replaced once pitting, haze or a drop in cut quality becomes visible.
A genuine Raytools 24.8mm x 1.5mm collimation-side window rated to 4kW, built to seat directly into standard Raytools collimation-lens holders.
Protects the collimating lens from spatter and dust, helps maintain stable beam quality, and keeps replacement quick and predictable on Raytools-equipped machines.
