Laser Power & Energy Measurement
Laser power meters you can use out of the box
Handheld meters with their own color display and battery — put it on the bench, aim the beam, read the number. For beams that live inside a machine, we supply online and embedded sensors too, from 500 pW to 3500 W.

Four meters that need no manual
These are the instruments most customers start with: switch on, measure, done. If you are not sure which one fits your laser, send us a photo of the machine and we will point you to the right one.
Handheld · 2 mW – 3000 W
Stellar V2
The all-rounder. Pick a thermopile head, switch on the 3.5-inch color display and read real power in seconds — no computer, no setup. Interchangeable heads cover 2 mW to 3000 W.
For marking & engraving
Caliber
Built for laser marking and engraving machines. Small enough for the tool bag, 10 W / 50 W / 150 W versions, Type-C charging and over 12 hours per charge.
Magnetic · up to 3 W
PowerMag
A one-piece detector with a magnetic back. Stick it where the beam lands, measure, lift it off and move to the next station — ideal for engravers, desktop markers and 3D-printing heads.
Weak beams · 500 pW – 3 W
Stellar-PD300
For beams a thermopile cannot feel. Photodiode probes from 500 pW to 3 W across 250–1800 nm, with automatic ranging and optional fiber adapters.
Building the measurement into your machine? Our Lynk (online), Trill (energy), Lynk-A (analog) and XFPT/XFPD (embedded) series are made for laser equipment builders — serial, USB, analog or TTL output, air- or water-cooled. See all nine series or our OEM & ODM capability.
Selection support
Not sure which meter fits? Tell us the laser
Most enquiries are settled with three numbers: working power, wavelength and beam diameter. Send those — or just a photo of your machine and what you want to check — and we come back with the right model, not the most expensive one.
- Handheld meters from 500 pW to 3000 W, probes 6–50 mm aperture
- Photodiode probes for pW-level and 250–1800 nm work
- Factory calibration with NIST traceability and field self-calibration
- Online and embedded sensors for machine integration
- Export documents handled in-house — FOB Ningbo or Shanghai
What to send us
- Power — average power in W, or pulse energy in mJ
- Wavelength — nm or µm, fixed or tunable
- Beam diameter — at the measuring position
- Mode — CW, pulsed, or both
- Where you measure — on the bench, or inside the machine
- A photo of the machine helps more than a long specification list

How we work
From your laser to a delivered meter
1
Describe your laser
Power, wavelength, beam diameter, CW or pulsed — or simply send a photo of the machine and what you want to check.
2
Get a matched model
We answer within one working day with the meter or sensor that fits your beam and budget — with unit price, MOQ and lead time.
3
Calibration & shipping
Units ship factory calibrated with NIST traceability, packed for export, with documents prepared before dispatch.
Send us your laser details and we will reply within one working day
Power, wavelength, beam diameter — or just a photo. If a meter is not the right answer, we will tell you that too.
