Structured Light Pattern Generating LaserCoherent’s Mini laser has the smallest dimensions available on the market for a diode laser producing uniform intensity lines. It is designed for years of reliable operation in systems where size and weight are a limitation. These patented line-generating optics have been integrated into the Mini laser to yield a high performance uniform line.

With its small diameter (10 mm), the Mini is packed with features. It is ESD-protected, reverse-polarity protected, over-temperature protected.

FEATURES

• Compact 10 mm diameter

• Power up to 35 mW

• 635 nm to 785 nm

• Uniform intensity distribution

• Focusable

• Fan angles from 1 to 75 degrees

• ESD, over-temperature, and reverse polarity protection

APPLICATIONS

• 3D Scanners

• Automotive

• Food Portioning

• Dental

• Machine Tool Wear

• Casting Profiling

• Alignment

ORDERING INFORMATION

To order, use the following code: MINI - Pattern (Interbeam Angle) - Wavelength & Power Option (if applicable) - Diode Power - Fan Angle (for lines) - Separate Electronics option. E.g., MINI-503L-1.5-635S-20-SD. Contact us for more details.

Definition Description

Fan Angle or Line Length Length of flat top profile, measured at 80% intensity clip levels. Reported in degrees for the fan angle.

Straightness Maximum deviation from the best fit line. Measured as the delta from the best fit line divided by the line length. Reported as a percentage.

Relative Intensity Floor Minimum relative intensity at any point along the line length. Reported as a relative intensity.

UNIFORM INTENSITY

Conventional laser line patterns are often generated by cylindrical optics that produce a Gaussian line profile with a bright center and fading ends. Coherent patented beam shaping optics distribute the light into an evenly illuminated line. The result is an exceptional, uniform line with sharp ends.

FOCUSING PERFORMANCE

The following figures show the typical focusing and depth-of-field performance of the Mini laser. The focus charts indicate the minimum line thickness (at 1/e2) achievable for a specific projection distance. The depth-of-field is defined as twice the distance over which the thickness of the line has increased by a factor of √2.
