The energy industry is primed for a wave of monumental change. The transition to renewable and alternative energy sources, advancements in energy storage, the rise of smart grids, and the electrification of transportation are driving significant changes domestically and globally. These developments mean organizations require new testing protocols, enhanced safety standards, advanced testing equipment, and comprehensive interoperability and cybersecurity assessments. Regulatory changes and technological innovations further complicate testing requirements, demanding scalable and real-world simulation capabilities. When testing facilities must adapt rapidly to support R&D efforts, it’s essential that they ensure the safe, efficient, and sustainable deployment of new energy technologies. All of these factors demand energy laboratories that are future-proofed for innovative solutions.

- The RL121 is characterized as a Small High Dispersion Bright Field ring light.
- Non-lensed LEDs disperse light at broad angles, providing “soft” lighting for applications that require short working distances.
- The low-profile design is only .56” (14.2mm) thick, allowing it to be used in space constrained applications.
- Optional adapter rings are available for camera lens mounting.
- A wide variety of wavelengths are available from UV to IR. An optional polarizer and/or diffuser may be used to further condition the light output.
- The RL121 delivers 27kLux at a working distance of 50mm.

- Eliminating all but a narrow band of light (+/- 40nm) centered on the specified wavelength, band pass filters are used to enhance colors, or to stop unwanted ambient light from reaching the camera.
- Filtering can replace existing shrouds, simplifying the physical set up of an inspection site.
- Ai offers 660nm and 635nm band pass filters to fit a number of different lens sizes.

- Reduced dark noise levels and improved dark offset
- Improved sensitivity, including NIR response
- In-camera image pre-processing (lens shading correction, pixel correction)
- Large full well when using in-sensor binning >142Ke
- Thousands of frames per second in Partial Scan Mode (ROI)
- Multi-ROI support (up to 32 ROI) and Cycling Mode
- Advanced Sequencer functions of different features

- The fourth generation of Ai’s popular Inline Control System.
- High Output Power: Capable of delivering 2.1 amps of continuous output and up to 8 amps in overdrive strobe at 24V, outperforming all other inline controllers on the market.
- Compact & Rugged: Sleek enough to fit through wiring conduit with its compact anodized aluminum housing and sealed to IP68 standards for prolonged liquid immersion and complete dust protection.
- Plug-and-Play Functionality: Enabled with SignaTech™, allowing for simplicity when overdriving, without risk of damage to the lighthead. For more information, please refer to the Product Manual

- The DF241 is characterized as a Small Low Angle Dark Field ring light.
- Precisely aimed LEDs provide a very low angle of incidence, radial illumination pattern.
- A scratch on a sheet of glass is a good example of a defect that can be detected with a low-angle dark field illuminator.
- With a light intensity of 24kLux at a working distance of ½” (12.5mm), the DF241 is perfect for imaging problems limited to a small field of view.
- A 25mm field of view is standard with an optional field of view of 35mm.
- Available in a range of wavelengths from UV to IR.
*Engineered to provide comparable optical characteristics to our previous RL1360.
