Laser Diode Modules
The instrumental quality CK laser module is designed to specifically address the needs of high-end OEM applications requiring superior optical quality, ultra-stable wavelength and output powers. The CK features an onboard microprocessor, allowing for advanced integration and user control. The mechanical design of the CK allows users to replace more expensive lasers without sacrificing performance.
Power Technology’s Instrument Quality (IQ) series of laser diode modules are designed specifically to address the needs of high-end OEM applications that require superior optical quality and ultra-stable temperatures, wavelengths and output powers. All IQ lasers feature anultra-precise operating current source and a PID temperature control loop that creates less excess heat within the laser module, increasing diode lifetime, efficiency and reliability.
The Power Technology machine vision portfolio includes the PNF and IQ7 and Grande modules.The PNF laser was designed expressly for 3D Machine vision applications including 3D profiling or mapping, dimensional scanning, high-speed rail or road inspection, web inspection and florescence. The uniform intensity line produced by the PNF directly supports these applications. The IQ7 dynamically reduces the laser’s coherent beam to ensure speckle reduction efficiency. The IQ7 dynamically reduces the lasers spatial coherence. This ensures the speckle is effectively eliminated.The device can be used in beam homogenization, 3-D scanning, metrology, microscopy and interferometry applications to remove local interferences. Additionally, we offer the Grande laser that provides up to 20 Watts of optical power for demanding applications that require high output powers.
The GWP is an entry-level cost and performance version of the Power Technology GPD product line, which include host laser diodes that do not have their own internal photodiode. The GWP is designed to operate in constant current mode, which also provides a more entry-level power stability option in the product portfolio.
The GPD Series laser modules are designed expressly to host laser diodes that do not have their own internal photodiode. The GPD overcomes this challenge by integrating an internal photodiode after a collimating lens. This configuration allows for Automatic Power Control (APC) mode of operation, which is not available on a majority of competing DPSS lasers at these wavelengths. The stability of this configuration cannot be matched by inexpensive DPSS lasers.
Power Technology’s PM family of lasers offers a variety of industrial-grade laser modules designed for use in standard or rugged OEM environments, and contains a precision current source ideal for applications demanding durability and stable output power.
The RS and GS laser diode modules are designed for cost-sensitive applications. The red RS lasers operate in automatic power control mode, while the green GS units use another control method to maintain stable output powers.
The IQ6 laser diode module is designed to address the needs of high-end OEM applications requiring narrow spectral widths and long coherence lengths. With wavelengths ranging from 390 to 2320nm, the IQ6 features a spectral width of < 5 MHz, and provides coherence lengths of more than 15 meters. The IQ6 laser features a precision current source and a PID temperature control loop that allows the unit to create less excess heat within the laser module, increasing diode lifetime, efficiency and reliability.
Power Technology offers a variety of laser modules that produce high-quality circular beams. Several of our modules employ anamorphic prisms to correct for the naturally divergent, elliptical nature of beams produced by laser diodes, while others achieve beam circularization via micro-lens or by coupling the beam into a fiber optic.
Power Technology offers microprocessor control over crucial operating parameters with on-board, menu driven, local control, or with Windows compatible control and monitoring software via USB or an RS-232 interface.
