The pattern is selected at the time of purchase. The cross and line patterns are ideal for precision alignment tasks, while the dot pattern suits targeting and positioning applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I adjust the focus on this laser module?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — the module features a fully \u003cstrong\u003eadjustable focus mechanism\u003c\/strong\u003e. Simply rotate the lens head to sharpen or spread the beam to your desired focus point. This makes it suitable for both close-range and longer-distance alignment tasks.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power level should I choose for my application?\u003c\/h4\u003e\n\u003cp\u003eA: The module is available from \u003cstrong\u003e10mW to 250mW\u003c\/strong\u003e. Lower power levels (10–50mW) are ideal for indoor alignment, DIY, and electronics projects. Mid-range (100–150mW) suits woodworking and stage use. Higher power (200–250mW) is best for industrial environments or longer projection distances. Always use appropriate laser safety eyewear for higher-power settings.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power supply does this laser module use?\u003c\/h4\u003e\n\u003cp\u003eA: The module operates on \u003cstrong\u003eDC 5V\u003c\/strong\u003e with a working current range of 10–280mA depending on the selected power level. A 5V power adapter with a 1.2m DC cable is included in the package, so it's ready to use right out of the box.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What beam patterns does this red laser diode module support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This 650nm laser module is available in three beam pattern configurations: Dot, Line, and Cross.
