TTL modulation adjustable focus 850nm infrared laser diode is an industrial grade device integrating 850nm near infrared laser source, constant current drive, TTL modulation, and adjustable focus structure. Cooperated with CCD/CMOS infrared camera and night vision device observation, it is widely used in industrial precision alignment, machine vision feature point marking, AGV tracking, night vision covert lighting, and laboratory optical path calibration.
Key features:
◆ TTL high speed modulation supports external TTL high and low level control of laser on/off, offering quick response, and meeting high speed dynamic applications.
◆ Qualified glass coated lens and adjustable focus lens output a near circular and sharp IR reference dot with small divergence angle, and freely adjusted IR dot diameter, suitable for high precision dot positioning and alignment.
◆ Invisible IR light emission from 850nm infrared laser diode within 5mW to 500mW avoids light pollution and visual interference, suitable for darkrooms, privacy protection, and precision measurement scenarios.
◆ Built-in constant current driving circuit and metal heat sink cooling system inside a durable metal housing provides excellent heat dissipation and vibration resistance. Reverse connection protection and overcurrent protection adapt to harsh industrial environments.
