Ventana scan optics
A new standard in scan engine optics
For decades, laser scanning optics have been constrained to the old standards used in conventional microscopes, including the physical dimensions of the tube lenses in those systems.
Here, with the Ventana family of scan engines and scan optics, Pacific Optica is introducing a new standard. We prioritize even optical performance across large fields-of-view. The scan engines are compatible with off-the-shelf objectives, and in fact the scan engines will squeeze every bit of performance possible out of most objectives. Also, the scan engines truly shine when using Pacific Optica objectives, such as the Cousa.

The Ventana Wide scan engine provides diffraction limited imaging across a large field-of-view with fast resonant scanning. For example, it provides a 3.2 mm x 3.2 mm field-of-view with a 10x objective (the Cousa objective). This is larger than a field number FN45 system, which means a diagonal dimension of 45 mm in the intermediate plane. This is the largest field-of-view scan engine available for commonly available microscope objectives. The combination of high etendue, to overfill large back aperture objectives, with rapid scanning at high angles, while preserving diffraction-limited performance is unprecedented.
The Ventana Fast scan engine provides the largest field-of-view available with 24,000 lines/s scanning. For example, with the commonly used Nikon 16x/0.8 objective, it scans 1.05 mm x 1.05 mm at 45 frames/s (512 lines per frame). With the Cousa objective, it provides 1.7 mm x 1.7 mm scanning at 24,000 lines/s (e.g., 1536 x 1536 pixel images at 15.6 frames/s). This is the largest field-of-view available for 12 kHz scanning systems.
The Ventana SL is a scan lens, and it can also be used in pairs as an optical relay. The Ventana TL is a tube lens, designed to work with the Ventana SL to form a high performance scan engine. There is nothing else like them available anywhere. Ventana SL and TL enable you to custom build two-photon imaging systems with a larger, higher fidelity field-of-view than other commercially available systems.
These components are a giant leap forward and are available in turn-key, complete systems. Write to info@pacificoptica.com for quote requests or questions.
