Frequently Asked Questions
Q: What is the wavelength of this near-infrared LED module, and why does it matter for night vision?
A: This module operates at 785nm (within the 775–790nm near-infrared range). This wavelength is invisible to the human eye but is highly effective for night vision cameras and IR-sensitive sensors, providing covert illumination without visible light disturbance — ideal for security and surveillance applications.
Q: Can I adjust the focus of this IR LED module, and how is it done?
A: Yes. The module features an adjustable focus mechanism that allows you to fine-tune the spot diameter to your working distance. At 1 meter, the spot diameter can be set to ≤ 5mm, making it suitable for both wide-area illumination and precision pinpoint targeting.
Q: What power supply does this 785nm LED module require?
A: The module operates on 8.5–12V DC with a standard AC adapter. Wiring is straightforward: connect the red wire to positive and the black wire to negative. If using a TTL-controlled setup, connect the yellow wire to positive and the supply wire to negative.
Q: Is this module suitable for continuous 24/7 operation?
A: Yes. The module supports continuous excitation mode and is rated for over 6,000 hours of service life, making it well-suited for round-the-clock security or industrial monitoring applications within its specified operating temperature range of -10°C to 40°C.
