Beam Profilers & M²

BEAMAGE-4M — USB 3.0 BEAM PROFILING CAMERA (350–1150 nm)

The core of the BEAMAGE range. A 4.2 megapixel CMOS camera with USB 3.0 connectivity — up to 10× faster than USB 2.0 — delivering accurate, ISO-compliant beam measurements out of the box. Sensor size 11.3 × 11.3 mm; minimum measurable beam 55 µm; dynamic range 1000:1 (60 dB). External trigger for synchronisation with pulsed lasers. Extends to 250–370 nm with the UG11-UV filter and to 1250–1350 nm with the B3-IR filter. Maximum average power 1 W (with ND filter).

BEAMAGE-4M-IR — PHOSPHOR-COATED FOR 1.5 µm (1495–1595 nm)

A variant with a phosphor coating on the CMOS sensor, converting 1.5 µm radiation to the visible band. Purpose-built for fibre laser and telecom applications around the 1550 nm band. Minimum measurable beam: 70 µm. All other specifications match the standard BEAMAGE-4M.

BEAMAGE-4M-FOCUS — LARGE APERTURE (20.5 × 20.5 mm)

Uses a fibre optic taper bonded to the CMOS sensor to increase the effective aperture to 20.5 × 20.5 mm without sacrificing the 4.2 megapixel resolution. Accommodates larger beam footprints where a focusing lens cannot be used. Minimum measurable beam: 120 µm. Accepts SM2 ND filters for power management.

BEAMAGE-M2 — AUTOMATED M² BEAM QUALITY MEASUREMENT SYSTEM

A complete, turnkey M² measurement system. A computer-controlled motorised rail moves two mirrors through a 400 mm optical path, sampling the beam at multiple positions. At each point, a profile is acquired by the integrated BEAMAGE-4M. The software fits the propagation data and calculates M², Rayleigh length, beam waist location, divergence angle, and astigmatism — fully compliant with ISO 11146 and ISO 13694. Measurement time: ~45 seconds (full frame) or ~20 seconds (ROI mode). Five interchangeable AR-coated lenses (200–500 mm focal length) and a three-position flip-mount attenuator (up to ND3.5, 8 levels) are included. M² accuracy ±5%; repeatability ±2%. Compatible with CW and quasi-CW sources, 350–1100 nm.

Main Specifications

Beamage-M2 Specifications

• LASER BEAM QUALITY MEASUREMENT (M²)
  • M² measurement for laser system qualification, acceptance testing, and ongoing QA. The BEAMAGE-M2 provides an automated, ISO-compliant result in under a minute with a full propagation curve and parameter report ready for documentation. Compatible with CW and quasi-CW sources from UV through NIR.
• BEAM PROFILING FOR PROCESS DEVELOPMENT
  • Characterise the spatial intensity distribution of a laser beam at the workpiece plane during process development. Understanding beam shape, centroid position, and ellipticity helps correlate optical performance with machining, welding, or ablation outcomes.
• OPTICAL SYSTEM DESIGN VERIFICATION
  • Verify that a focusing or beam-shaping optical design delivers the expected spot size, shape, and profile at the target plane. The BEAMAGE range covers the beam sizes relevant to most photonics and laser system development work.
• FIBRE COUPLING & BEAM DELIVERY OPTIMISATION
  • Profile the output of fibre cables, beam delivery systems, and collimating optics to verify mode quality and optimise coupling efficiency. The BEAMAGE-4M-IR extends this to 1550 nm fibre outputs.
• POINTING STABILITY MONITORING
  • The beam-tracking display mode plots the centroid position over time, providing a direct measurement of laser pointing stability for applications in precision manufacturing, interferometry, and long-path optical systems.
• POST-MAINTENANCE BEAM VERIFICATION
  • Confirm that beam quality is restored to specification after optics cleaning, lens replacement, or module changes. The BEAMAGE-M2’s repeatable, automated measurement makes before/after comparison straightforward.
• UV & IR LASER CHARACTERISATION
  • With appropriate accessories (UV converter, IR adaptor, filter sets), the BEAMAGE range covers sources from the UV to beyond the silicon cutoff, including excimer, Nd:YAG harmonics, and short-wave IR sources.
