TTL modulation adjustable focus 445nm blue laser diode module cooperates qualified import 445nm blue laser diode, optic lens inside a high duration anodized aluminum alloy housing tube, it allows for high concentration blue light source generation, and efficient conversion of highly bright and precise blue dot indication. Adjustable focus optic lens enables increasing accuracy and brightness blue reference dot alignment source for both industrial, medical and scientific experimental fields effectively.
Key features:
◆ TTL modulation supports 0–100kHz square wave modulation (0V off / 5V, 9V, 12V on), high frequency pulse modulation is possible, suitable for fully automated production lines and programmable experimental equipment.
◆ Adjustable focus lens allows for freely focused so as to achieve high precision dot positioning with a very small light spot at close range and quickly finding point at long distance.
◆ Metal heat sink cooling system inside an anodized aluminum alloy housing tube achieves high heat dissipation efficiency, built-in overcurrent, overvoltage, and overtemperature protection, avoids spot deviation and temperature drift during long term continuous operation.
◆ 445nm short wavelength blue light enables fine dot projection, low reflection and no glare on highly reflective workpieces, such as copper, aluminum, and titanium alloys, and clear light spot visibility in high brightness.
