High performance TTL modulation adjustable focus 515nm green laser diode module combines a quality 515nm green laser diode, precision optic lens and a constant current driving circuit, supported by TTL signal modulation and focus adjustment, outputting a clear, bright and low divergence circuit green reference dot. It offers superior visibility green light source, which is particularly suitable for applications such as industrial machinery processing, machine vision, scientific experiment and education etc.
Key features:
◆ High speed TTL modulation signal control enables on/off switching and pulse modulation, suitable for machine vision strobe lighting, dynamic speed measurement, and laser marking.
◆ High visibility 515nm green light with adjustable focus can be freely adjusted of both laser beam divergence and focal distance, achieving a fine focal green dot to accommodate various working distances.
◆ Qualified glass coated lens produces a highly circular dot with sharp edges, freely from temperature fluctuation or stray light, ensuring high precision dot positioning and stable imaging.
◆ Built-in APC, ACC driving circuit board enables constant output power and electric current supply. Combined with anodized aluminum alloy housing tube and efficient heat dissipation, it supports continuous operation with stable, reliable performance.
