Wavelength & Power
3D scanning typically uses a red laser. The specific wavelength will depend on the sensitivity of the camera being used. The power level of the lasers is extremely important as in this type of application adherence to laser safety classifications is crucial and the lasers must be eye-safe. the compact laser modules are available with output powers up to 4.5mW. With access to laser diodes from all major manufacturers, ProPhotonix can source the optimum diode for each application.
The laser line modules are available with a 58° 88° or 120° fan angle to allow for the line length and working distance required by your application. The laser modules are designed and built to produce a consistent, thin laser line and the appropriate depth of focus to optimize image resolution. Custom optical configurations are also available.
ProPhotonix’ in-house manufacturing ensures that we can produce laser modules to tight specifications and our stringent quality procedures ensure that you receive repeatable results every time. Repeatability of the fan angle of the laser and the resulting laser line length is important to guarantee the consistent performance of the 3D scanner. If the fan angle of the laser is too small the scanner will not be able to scan the required sized object.
Robustness, reliability and repeatability are key criteria when developing a laser for 3D scanning. Custom laser prototypes undergo significant product testing in the development phase and in manufacturing. ProPhotonix has put rigorous testing procedures in place to guarantee repeatability of key measurements.
