Photonic offers variable-focus laser diode modules

Constructed to withstand harsh conditions and satisfy challenging industrial applications, Photonic's new range of variable-focus industrial laser diode modules offers the high performance and the high boresight accuracy of less than 0.25 degrees of the existing range of standard industrial laser modules with the added bonus of user-adjustable focus for greater flexibility and fine tuning.

The range is designed to be a complete original-equipment-manufacturer (OEM) laser solution for heavy-duty manufacturing processes such as micro-machining, marking, cutting, drilling, welding, forming and soldering, along with other industrial laser uses where quality, durability and robust performance are critical.

The industrial modules are encapsulated in a hard-coat-anodised case with a scratch-resistant sapphire window to protect the lens.

They are designed and built for ease of use; any time the laser needs to be changed, the connectors - either 2.5mm DC jack or industrial screw-on - make installation and replacement easy and their compact size allows for efficient integration into existing production systems.

The variable-focus industrial laser module is available in a variety of wavelengths from 635nm to 830nm with optical output powers from 0.97mW to 27.50mW, with either a standard elliptical output beam or line-generating optics that provide a 45-, 60- or 90-degree full fan angle line, offering straight-line precision without bowing.

The beam is aligned to less than 0.25 degrees to the mechanical axis of the laser, giving high boresight accuracy.

With optical output powers from 0.95mW to 27.50mW, an operating voltage of 5VDC regulated +/-10 per cent and an operating temperature from -10C to +50C, the modules are static, surge and reverse polarity protected and RoHS compliant.

The standard lens may be replaced by other optical systems such as line or cross generators.
