IR Laser Illumination Series

Infrared laser illumination lets you see at night while staying unseen. It lights the scene in a band invisible to the human eye, and a camera sensitive to near-infrared turns that into a normal picture.

Two wavelengths

850 nm and 940 nm are common. 850 nm is more efficient in range: the camera sensor is more sensitive to it, but part of the emission shows as a faint red glow. 940 nm is almost invisible to the eye, which matters for covert work, but demands a more sensitive camera and gives up some range.

What to compare

• Wavelength: 850 nm for range, 940 nm for covertness.
• Beam angle: narrow for distance, wide for area coverage.
• Power: matched to the task and safety rules.
• Power and control: voltage and activation from the controller or gimbal.
• Compatibility: camera sensitivity in the infrared band.

Frequently asked questions

Is the illumination visible to the eye?

850 nm shows a faint red glow in darkness. 940 nm is practically invisible.

Do I need a special camera?

Yes, one sensitive to near-infrared. A normal camera with an IR-cut filter will not see the illumination.

Which to choose for covert work?

940 nm: it does not reveal the operator's position, though it needs a more sensitive sensor.

Is it safe?

Laser emission requires care: never point it at eyes or people, and respect the device class and local rules.

Can brightness be adjusted?

Many models allow power or beam-width adjustment. Confirm availability.

Does it help in daylight?

No; the point of illumination is night work. Daylight makes it unnecessary.
