Ring lights can be used to illuminate your sample from above, increase the amount of reflected light, and view samples where observation with transmitted light is not possible. This model is designed to be attached to objectives up to 45 mm in diameter. The outer diameter is 75 mm. The controller reliably regulates the lighting and offers many advantages: precise and reproducible adjustable brightness as well as visual feedback of the current setting and storage of the last selected setting. The automatic standby mode protects the LED lighting and reduces energy consumption by 90%.
