Bystronic 4-09046-2 Copper Reflector 50mm x 10mm

Bystronic 4-09046-2 Copper Reflector 50mm x 10mm is a copper folding mirror (MMR) used as a PLM optic in Bystronic laser heads, serving as a precise, drop‑in replacement for the folding mirror path. The part is listed under Bystronic references 4-09046 and 4-11018, specifying a Ø50 mm copper mirror with a 10 mm thickness and a 100 MCC rating, with optical reflectivity greater than 99.8% to help preserve beam quality in high‑power applications such as laser cutting and engraving. This copper MMR is designed for use in Bystronic PLM assemblies and supports compatible SPT/UC optical paths, making it a common choice for maintenance and service to restore original performance. Its copper construction aids heat transfer at the folding interface, helping to minimize thermal distortion during extended operation and maintain consistent focus across the laser train. Typical applications include replacement in Bystronic laser systems where a high‑precision folding mirror is required to sustain accurate beam steering and cut quality.
