Ryf AG | RL4-UV LED RING LIGHT

RL4-UV400 / 375 / 365 UV LED Ring Lights

The LED ring light series RL4-UV is primarily designed for illumination tasks in UV microscopy, where the use of monochromatic light with short wavelengths results in higher resolution and improved contrast.

The RL4-UV, with a standard diameter of 66mm, delivers uniform, shadow-free, and flicker-free light, suitable for any type of microscope. Reducer rings in various sizes allow perfect adaptation of the ring light to other diameters up to 50mm.

The ring light consists of 48 high-quality UV LEDs with a wavelength of 400nm. Variants with 375nm and 365nm are also available. After the LEDs reach the end of their lifespan (see technical data), the LED light module can be easily replaced by a new one at the factory.

Key Features:

• Uniform and shadow-free illumination
• Flicker-free operation
• Higher resolution due to monochromatic light with shorter wavelengths
• Improved contrast through absorption of UV light
• Continuous brightness adjustment with a convenient table controller (Table Control TC250)
• Adaptable to smaller diameters up to 50mm
• Easy and fingerprint-free attachment with stainless steel clamping screw
• Equipped with high-quality industrial connectors with snap-lock mechanism
• Energy-saving and environmentally friendly lighting technology.

Note: This device emits intense ultraviolet radiation during operation. Much of it is invisible. The radiation can harm your health. Protect your eyes and skin during operation.
