Description
Nichia NUBM35 Blue 14LDs 455nm 67W Laser Diode Chip Array
Electrical Parameters
Operating Current: Ensure the driving current is within the rated range of the laser diode to avoid overloading or underloading.
Operating Voltage: Use a power supply that matches the rated voltage of the laser diode to prevent overvoltage or undervoltage.
Constant Current Drive: Use a constant current power supply to avoid current fluctuations.
ESD Protection: Wear an anti-static wristband during operation to prevent electrostatic discharge damage.
Thermal Management
Heat Dissipation Design:Ensure proper heat dissipation using heat sinks, fans, or thermoelectric coolers (TECs).
Temperature Control: Monitor the operating temperature to avoid overheating (typically not exceeding the maximum operating temperature).
Heat Sink Installation: Properly install the heat sink to ensure good contact with the laser diode.
Beam Control
Beam Alignment: Ensure the laser beam is properly aligned with the target to avoid misalignment or scattering.
Beam Divergence: Adjust the beam divergence as needed using lenses or optical components to optimize beam quality.
Beam Path: Ensure the beam path is free of obstacles to prevent accidental reflections or scattering.
Safety Precautions
Laser Safety Class: Understand the safety class of the laser diode (e.g., Class III) and take appropriate protective measures.
Protective Eyewear: Wear safety goggles matched to the laser wavelength to avoid direct exposure to the eyes.
Avoid Direct Exposure: Never direct the laser beam at eyes, skin, or reflective surfaces.
Environmental Conditions
Operating Temperature: Use the laser diode within its specified operating temperature range.
Humidity Control: Avoid using the laser diode in high-humidity environments to prevent condensation or corrosion.
