The Aven Tools 26200B-209 E-Arm Focus Mount with Integrated LED Ring Light includes a built-in 60 LED ring light with dimmer control and daylight color temperature. The LED lights have a long life of at least 20,000 hours and also consume very low amounts of power. A control box with a dimmer provides brightness control of the LEDs.

The focus mount features a tiltable E-Arm design that can be set to the desired inspection angle. It will fit Aven's Binocular and Trinocular stereo zoom microscopes. Users can create a custom microscope system by attaching the focus mount to a boom or articulating arm stand.
