On the door

Unmistakable, from the hallway

Calm green when the lab is safe - bold red and impossible to miss the moment a laser fires. The same display, automatically.

Why Beam Sentinel

Three things every laser lab needs

One device at the door takes care of safety, awareness and record-keeping - without changing how people work.

More safety

The Sentinel Link mirrors the live laser state and can feed a signal into your laser's interlock loop. It de-energises on signal loss and shows unmissable warnings at the door.

Live lab status

See at a glance - at the door or remotely - whether the laser is on, who is inside, which wavelength is in use, and whether the interlock is connected.

Audit-ready records

Every exposure is logged automatically - who, which laser, when, how long, at what wavelength. Append-only and exportable as CSV for your safety records and good-practice record-keeping.

The entrance sign

A glanceable display at the lab door. Green when safe, red and impossible to miss when a laser is in use - with the wavelength, entry policy, who's inside, and the interlock's live status.
