Configuration notes and measurement conditions
- [1] For the TEM00 mode laser beam, with a central incidence, the spot size is2.9 mm. [2] It is working temperature, if it involves directivity test, the temperature should be controlled at 15-25°C.
- Read total power, power density and pulse-energy-density limits with the stated attenuation, wavelength, beam size, cooling and detection time.

From image to measurement
Beam analysis and software
Illustrative software output. Results, analysis functions and acquisition rates depend on the selected hardware, software and beam conditions.
Follow beam characteristics
Analyse beam diameter, ellipticity and position. Suitable configurations support multi-spot monitoring, image stitching and pointing-stability analysis; acquisition and processing rates are model dependent.
Choose the measurement configuration
Check exposure, shutter and external-trigger support for your timing requirements. The 1000 W system specifies beam analysis and optional automatic M² workflows; these capabilities require the stated software and hardware configuration.
Specify the complete measurement
01
Match the wavelength
Choose the exact detection band and the attenuation or window configuration. A family range combines different models; it does not make every instrument broadband.
02
Resolve the spot
Compare the minimum detectable spot with the maximum usable beam size. Sensor pixel size, optical magnification and quoted measurement resolution describe different quantities. Gaussian TEM00 limits may be smaller than the sensor aperture.
03
Check power and exposure
Read total power, irradiance and pulse-energy-density limits together. Include pulse duration, repetition rate, beam diameter, cooling and the permitted measurement time. Attenuation conditions belong to the quoted limit.
04
Plan acquisition and alignment
Match USB or GigE, trigger support, software requirements and beam-entry geometry. Divergence needs measurements at known axial positions; automated M² analysis requires the appropriate scan hardware and software configuration.
Technical FAQ
Configuration questions for CN0204VIS-M
Does the largest model power rating apply to every laser?
No. The rating depends on wavelength, beam diameter, attenuation, cooling and operating time. For example, the 500 W configurations distinguish 200 W, 300 W and 500 W operation by focused-spot size and measurement time. The 1000 W model specifies continuous operation with water cooling.
Is the sensor aperture the maximum Gaussian beam diameter?
Not always. Several models give a smaller TEM00 or 1/e² beam limit than the geometric sensor range. Read the model footnotes and central-incidence conditions alongside the main table.
Can a single camera image measure divergence or M²?
A single profile gives the transverse distribution at one plane. Divergence and M² require measurements along the propagation axis, suitable optics and a defined analysis method. Confirm the translation, attenuation and software configuration for that workflow.
Which computer and interface are required?
Most listed models specify Windows 10 or 11, 64-bit, with MS Office or WPS, at least 8 GB RAM and a processor of at least 2.5 GHz with four or more cores. USB3.0, GigE, 10GigE and trigger availability vary by model; use its exact specification.
