parameter

Wavelength: 520nm

Power: 3W

Beam diameter: The beam diameter at the light outlet is about 30MM (3CM)

This laser is synthesized by special processing of three 1W laser diodes, with a power of around 2.8-2.9W. The beam can reach 30MM after passing through a beam expander. You can clearly see the light spot at around 100 meters under sunlight, around 500 meters on cloudy and rainy days, and around 1-2000 meters at night. The light beam is very obvious at night! Suitable for landmark lights or bird repellent use, there is no problem driving birds within 100 meters under sunlight!

Non adjustable focus!

Power can be adjusted through PWM signals! Supports TTL modulation!

Must read before purchase:

1. The laser power module is relatively large, so eye contact is prohibited, otherwise it may cause permanent blindness, and the consequences are at your own risk!

2. Do not use in flammable and gas environments to avoid fires and explosions.

3. Children are prohibited from coming into contact with this laser product.

4. This laser requires a 12V 5A power supply to drive it,

5. Do not open the module to prevent damage.

6. PWM/TTL: 0-5V, frequency<18K

This laser can be used to modify into a laser bird repellent, as it has a high power of 3W and can be clearly seen in sunlight, which cannot be achieved with 1W green light. Tested to be effective in repelling birds under sunlight, please watch the main video for details.

Laser bird repellent principle:

For birds, vision is the most sensitive, especially for green lasers with wavelengths of 520-532nm. The laser bird repellent utilizes this feature, with a green laser simulating the conditions for biological visual reflection during operation. When the green laser scans over, the bird looks like it sees a green stick, achieving the bird repellent effect

Birds are afraid of green light, so when emitted from laser emitters, they also emit a strong green beam, which has a huge deterrent effect on the "bird generation". The laser bird repellent emits a striking second level green laser for visual safety, which, when irradiated near birds, causes them to panic and flee. The green laser beam it emits can scan runways and grasslands. This product is suitable for evening or night bird repellent work in airports, orchards, farmland, warehouses, and power grids.
