Laser Profile Scanners use blue laser diode.

Press Release Summary:

Laser Profile Scanners use blue laser diode.

May 22, 2014 - Based on laser line triangulation, scanCONTROL 26xx/BL and 29xx/BL use short wavelength of 405 nm, making them suitable for use with red-hot glowing metals, semi-transparent materials, and organic materials. Profile frequencies up to 4,000 Hz enable sensors to be used in high-speed applications, such as measurement of rail tracks on moving trains. Offering measuring ranges from 25–265 mm in z-axis and to 143.5 mm in x-axis, scanners output measurement data via Ethernet or serial interface.

Laser Scanner Makes it Blue

Press release date: May 22, 2014

The scanCONTROL series of laser profile scanners has been extended with two additional models that use a blue laser diode: scanCONTROL 26xx/BL and 29xx/BL.

The sensors are based on the laser line triangulation. The innovative aspect of the sensors is their use of a short wavelength of 405 nm. The special characteristics of this wavelength range enable the sensors to be used in conditions where measurements have not been practicable to date. The sensors even operate on reflective or transparent surfaces, where it is not possible to use optical measurement methods. 

The scanCONTROL 26xx/BL and 29xx/BL models offer the same excellent features as the recently launched scanCONTROL 26xx and 29xx series that use a red laser diode. The entire control technology is integrated in an extremely compact design, enabling their application in complex machines where there may be little space for mounting of sensors. Profile frequencies of up to 4,000 Hz enable the sensors to be used in high speed applications, for example, in the measurement of rail tracks on moving trains. Different measuring ranges are available from 25 mm to 265 mm in the z-axis (distance) as well as to 143.5 mm in the x-axis (laser line length). Output of measurement data is via Ethernet (UDP, Modbus) or serial interface (RS422, Modbus). In addition, analogue signals or digital switch signals can be output via an output unit.

The scanCONTROL 26xx/BL and 29xx/BL blue laser profile scanners are ideally suited to the following applications and materials:
- Red-hot glowing metals: The red glow normally “dazzles” red profile scanners, but blue scanners are unaffected.
- (Semi-) transparent materials: Due to the short wavelength, the blue laser line penetrates significantly less into the surface than the red laser.
- Organic materials: Slight penetration behaviour of blue laser results in higher measurement accuracy.
