High white light transmission

All SCHOTT microscopy light guides use PURAVIS® eco-friendly glass optical fibers to offer high light transmission and low color shift. And thanks to an improved numerical aperture, the light guides capture more light at their source, leading to a brighter, more intense output.

Product variants

The optimal illumination of objects under examination is the most decisive factor for accurate results in stereo microscopy. The range of products and accessories in SCHOTT’s Fiber Optic Light Guide series ensures that you receive the very best contrast for your application.
