2024 - Revolution HyperSpectral

Discover a world of hidden colors underwater with Led Light Revolution Hyperspectral. Our innovative technology illuminates your underwater explorations with a powerful, customizable light, revealing details invisible to the human eye.

Lamp with white LEDs and infrared LEDs emit light from 400nm to 940nm:

The lamp is composed of two types of LEDs, providing both visible and infrared illumination, essential for overcoming the limitations of underwater lighting.

• White LEDs (CRI > 95):

  • With a CRI > 95, white LEDs guarantee excellent color rendering, closely mimicking natural light, important for tasks requiring precise color perception underwater.

  • Emission spectrum: These LEDs emit light from 400nm to 700nm, covering the visible spectrum, allowing the camera to capture detailed and accurate images in clear and shallow waters.

• Infrared LEDs (730nm, 810nm, 850nm, 940nm):

  • Emission spectrum: IR LEDs emit light in the near-infrared range (700nm-1000nm), which can penetrate water more effectively in certain conditions compared to visible light, especially in turbid waters where visibility is reduced:

    • 730nm: On the boundary between visible red and NIR, it offers improved visibility in shallow waters or where minimal scattering is desired.

    • 810nm, 850nm: Commonly used in environments where visibility is compromised due to suspended particles in the water.

    • 940nm: Provides deeper penetration into water and is useful for specialized imaging techniques, such as assessing material composition or detecting objects in turbid waters.

Drivers:

• Two independent drivers:

  • One controls the white LEDs, ensuring stable illumination and a high CRI to capture vivid and natural colors.

  • The other powers the IR LEDs, allowing independent adjustments of infrared light intensity based on underwater conditions.

Underwater applications of the system: The lamp is designed for use in conjunction with the LeoR housing and the Specim IQ Hyperspectral camera. The lamp is particularly suitable for underwater applications where light scattering, absorption, and limited visibility can hinder traditional imaging techniques:

• Marine exploration and research:

  • In clear waters, white LEDs provide natural illumination, allowing the camera to capture high-quality images of coral reefs, marine plants, fish, and geological formations with accurate color reproduction.

  • In deeper or turbid waters where red and visible light is absorbed, IR LEDs provide additional illumination. Infrared light can help identify objects, underwater structures, or organisms that may not be visible with white light alone.

• Surveillance and security:

  • The system can be used for underwater surveillance in ports, docks, or other areas where visibility is compromised by sediment, algae, or low light conditions. IR LEDs offer an advantage, especially for identifying threats or tracking objects hidden or camouflaged in the water.

• Underwater robotics and autonomous vehicles:

  • This camera-lamp combination is ideal for autonomous underwater vehicles (AUVs) or remotely operated vehicles (ROVs) that need to navigate and acquire data in challenging underwater environments. The dual illumination system allows robots to adapt to water clarity and changing light conditions, using white light in clear waters and infrared light in turbid environments.

• Marine archaeology:

  • To explore and document shipwrecks or submerged historical sites, the system allows archaeologists to see fine details that might be lost using visible light alone. Infrared light can sometimes reveal surface textures or material compositions not easily distinguished with visible light.

• Biological studies:

  • The system can be used to study the behavior of marine life without disturbing the environment. Infrared light is less likely to interfere or scare wildlife, allowing researchers to observe nocturnal behaviors or low-light conditions with minimal disturbance.
