TTL modulation 520nm green dot laser alignment utilizes a 520nm semiconductor green laser source and a qualified optic lens, outputs a circular dot with compact and high visibility. External TTL level control enables on/off switching or pulsed modulation. Cooperated with adjustable focus lens, it allows for high precision dot alignment for industrial precision dotting, alignment, and visual calibration.
Key features:
◆520nm green light emitting from a qualified glass coated lens and 520nm wavelength laser diode remains visible in workshop lighting or outdoor environments.
◆Excellent TTL high speed modulation power source supports 520nm green laser module with high/low level switching, 1Hz-1MHz modulation, enables easy on/off control of laser.
◆Adjustable focus lens enables a circular dot with low ellipticity that remains its shape over long distances, no light blur or dim.
◆Built-in APC driving circuit inside an anodized aluminum alloy housing tube outputs stable green light and green reference dot, bears thermal drift and vibration, ensuring minimal brightness or positional shift during prolonged operation.
