Flexible Optical Configurations

A 20x objective (NA = 0.6) with a long working distance offers enough space for various and non-flat samples. Additionally, an inverted 100x immersion objective with a numerical aperture of 1.45 ensures an enormous light collection efficiency.

Parabolic Side Mirror

A parabolic mirror (NA = 0.9) provides efficient excitation and emission light collection from the tip. The mirror design ensures a single focus point for a wavelengths range from 350 nm to 10 Ám.

Customizable Optical Configuration

Optical ports in different heights provide customizable optical configuration and full access to excitation (illumination) and emission of the sample. The beam path is adjustable via a periscope. All parts and ports are fully compatible to Thorlabs 30 mm cage system and can simply be excanged or modified.
