Laharco® Green Diode Lasers

The new Laharco® self-contained assembly provides intense green light in three power configurations. Operating from 90VAC to 260VAC, these new diode pumped lasers maintain constant output power for ambient temperatures from 0^◦C to 40^◦C.

The intense green beam is useful for visual applications in harsh or industrial environments, with optics housed in a sealed cell to provide added protection against contaminants and moisture.

Features

• 532nm Tem₀₀ Operation
• Power Stability Better Than ±5% Over 8 hours
• Rugged Industrial Packaging
• Entirely Self-Contained
• No Additional Heat-Sinking Required
• 90VAC to 260VAC, 50Hz/60Hz
• 12 Month Warranty

Common Models

• Model GLD-9810 - 10mW Green Diode
• Model GLD-9830 - 30mW Green Diode
• Model GTD-2152 - 15mW Green Diode (Thermal Cooling)
• Model GTD-2302 - 30mW Green Diode (Thermal Cooling)

Each Green Laser is equipped with:

• Laser light emission indicator, which provides a visual indication the laser is on.
• Aperture to provide total beam attenuation.
• Identification, certification, caution, and aperture label permanently affixed to the housing.

Laharco Helium-Neon Lasers

For the wood products, paper, textile, metal, food processing and other industries, accurate cutting is crucial to productivity. Miscuts add up quickly to account for a significant waste factor. Laharco Laser Technology, with its many unique options and models to fit specific industry needs, can maximize yields.

Features

The powerline lens, manufactured in-house by Lacey-Harmer Co., transforms the laser beam into a projected laser line even in width and intensity from end-to-end. This eliminates the problem of a projected line which is wider in the middle and fades toward the ends. Quality of the lens and professional alignment produces a line "string-straight", second to none in the industry. Custom optics are designed to meet specific customer applications.

Laharco Lasers are available in a wide range of models for your best mounting configuration.

The User-Adjustable Intensity™ option allows mill personnel to install the laser and then fine tune the projected laser line for maximum operator visibility and more effective mounting.

Laser heads are mounted with a special shock absorbing materials and are 100% tested to meet Laharco's exacting standards for power output. Power supply units are installed with special protection against dirty line current, a major cause of power supply failure. This means greater reliability and longer laser life.

Superior construction throughout, from the rugged Schedule 40 Anodized aluminum housing, to the soldered electrical connections, to the airtight seal on every laser. Every attention to detail means you get a laser with the industry's highest reliability, backed by Laharco's Full Warranty.

Curve Catcher - Proven System to Monitor and Display Sawing Deviation.

Because the saw is the key to log breakdown, the Curve Catcher system is a practical tool to use to increase production while maintaining superior quality control. The on-line system allows mill personnel to operate and maintain their saws more efficiently and assures the highest possible production and recovery.

The Curve Catcher gives a sawyer the feedback necessary to maintain maximum feed rates. It assists in feed rate adjustments to compensate for variances in wood temperature, density and saw tooth sharpness. If teeth become dulled by gravel or other foreign objects, the condition is detected immediately. Speed is corrected to maintain saw stability while alerting the mill personnel to the need for a saw change.

Knowing the amount of deviation of the saw while in the cut provides quality control supervisors and filers with a valuable tool. Operating and benching techniques, along with kerf reduction can all be evaluated with the Curve Catcher. The system uses a special type of sensor, mounted to the underside of the top saw guide, to monitor and display deviation of the saw in increments of 0.1mm (.004 inch). Deviation and direction of movement is displayed on a bar lamp, as well as a digital reading, on the Main Control Unit.

The basic Curve Catcher (FCC107D) is a complete unit to monitor one saw blade. With the use of a sensor switcher kit, two sensors can be monitored on an alternating basis. This option is designed for automatic operation on double cut headrigs or manual switching on twin bandsaws.

Curve Catcher can also provide a deviation output signal with the Analog Output unit (FCC107DA). The unit connects easily to a Chart Recorder, or properly equipped PC, to provide a high resolution readout of deviation throughout the cut.
