Frequently Asked Questions
Q: What beam patterns does the 405nm laser diode module support?
A: This focusable laser module supports three beam patterns — Dot, Line, and Cross. You choose your preferred pattern at the time of purchase. Each pattern uses precision K9 glass and wavy glass optics for a sharp, well-defined output.
Q: What power output options are available for this violet blue laser module?
A: The module is available in 100mW, 200mW, and 300mW output levels. Select the power level that best suits your application — lower power for fine alignment tasks and higher power for more demanding positioning or stage lighting uses.
Q: What voltage does this laser diode module require, and is a power adapter included?
A: The module operates at DC 5V and draws between 110mA and 210mA depending on the selected power level. A 5V power adapter and mounting holder are included in the package, so you can get started right out of the box.
Q: Is the focus of this laser module adjustable?
A: Yes. The module features an adjustable focus mechanism, allowing you to fine-tune the beam sharpness and spread for your specific working distance. This makes it suitable for a wide range of alignment and marking applications.
