100× Objective Lens - Imaging at the Diffraction Limit (~100 nm Features)

Achieve true diffraction-limited optical imaging down to 100 nm.

The Mounted LEDs 100× objective lens delivers exceptional diffraction-limited performance, enabling the visualisation of structural features as small as ~100 nm on standard optical microscopes. The lens fits all major microscope brands, with optional thread adapters available when required.

With a working distance of 0.23 mm, this objective combines high numerical aperture performance with ample clearance, allowing easy imaging of reflective, nanostructured, and delicate samples.

Its performance has been experimentally verified through several benchmark tests:

​

• Imaging the periodic groove structure of a Blu-ray disc in white light reflection mode (100 nm grooves, 200 nm track pitch).

• Resolving 90 nm calcium carbonate nanoparticles (PlasmoChem GmbH) in transmission mode (white light illumination).

• Imaging zinc oxide nanorods (90 nm diameter × 1 µm length, Sigma-Aldrich Product Code 773999-500MG) under transmission white light illumination.

Each objective is individually tested and supplied with a Blu-ray reference sample enabling users to reproduce and validate the lens’s performance in their own lab. Additional test samples are available upon request.
