The Pryer lens is a new endoscopic objective compatible with common optical microscopes, especially modern Two-photon microscopes. An unconventional optical design combines a very small tip size to be minimally invasive with a large numerical aperture for high resolution.
This state-of-the-art objective allows for in vivo deep tissue access and visualization in difficult-to-reach regions such as the hippocampus. Image acquisition with subcellular spatial resolution at sub-second sampling rates becomes a reality.

The Pryer lens is a combined endoscopic objective and is compatible with any fluorescence microscopes, such as current Two-photon microscopes from Olympus and Nikon. This state-of-the-art objective allows for deep tissue access and visualization in anesthetized animals, awake animals with head fixation, and even chronic recordings.
It is composed of 7 lenses within its unique slim tip which makes it suitable for minimally invasive endoscopic imaging applications.
|Type||Plan Fluorite NIR|
|Correction||Infinity / Zero cover glass thickness|
|Tip diameter||2.1 mm|
|Field of view||200µm|
The Pryer lens is compatible with all major types of objective mounts.
