Laser scanning on your equipment entails tradeoffs between speed, resolution, and field-of-view. Pick 2 of those 3. Now you can get all 3, with this breakthrough. www.laserfocusworld.com/optics/artic... Thanks @laserfocusworld.bsky.social

Huge field-of-view, fast, high res. two-photon imaging. This technology (paper link below) is available now, in the Ventana products. Sold as complete turnkey systems, or components. pacificoptica.com/ventana/ Installations are happening now at some of the best labs in the world.

An excited customer, sharing photos of the optics they just received. And one of the first Avocado objectives in customer hands. It's a Cousa-class objective, with an NA of 0.6 and a WD of 10 mm, optimized for 2p, and excellent performance out to the edges of the field-of-view. More info soon!

Loving the "CEO eats his own burger/hot dog/..." stuff. Pacific Optica's CEO uses his own Ventana, Diesel2p, and Cousa products. They're the high throughput, turnkey, workhorse systems that power the lab. pacificoptica.com/ventana/ pacificoptica.com/diesel2p/ pacificoptica.com/cousa/

“Because [science] is the most effective way of learning about the physical world, it erodes superstition, ignorance and prejudice, which have been at the root of the denial of human rights throughout history…” -Baron Taverne

“Because scientific knowledge is tentative and provisional, it is the enemy of dogma.” -Baron Taverne

“Because science rejects claims to truth based on authority and depends on the criticism of established ideas, it is the enemy of autocracy.” -Baron Taverne

In 2025, we unlocked new frontiers in multiphoton optics and imaging. In 2026, you can get the best 2p systems you’ve ever seen. Accelerating your work. Higher throughput. Easy to use. Focus on your neuro work, and leave the 2p to PacOp.

Happy Halloween! pacificoptica.com/cousa/

Check out some sweet Ventana Wide + Cousa imaging. pacificoptica.com/ventana/ Live raw data over a 3.2 mm wide field-of-view with 16,000 lines/s scanning and submicron resolution. Demo now at @omibs-mbl.bsky.social Thx @ewadorotaz.bsky.social @mbfbioscience.bsky.social @crisrodtsou.bsky.social !

Scientists explore, measure, gather evidence, figure things out, and share openly. Their work benefits us all. Demo imaging at MBL/Woods Hole and CSHL this summer. Explore further. pacificoptica.com

Put whatever objective you want on the Ventana Wide. It will give you the largest field of view with high speed scanning: eg, 3.2mm x 3.2mm with a 10x. Fast, flexible 2p imaging. Che-Hang Yu is helping MBL courses with this Ventana Wide system pacificoptica.com/ventana/

Just landed in Woods Hole for summer courses: a Full Ventana Wide system. pacificoptica.com/ventana/ with a Cousa pacificoptica.com/cousa/ www.mbl.edu/education/ad... www.mbl.edu/education/ad... Thanks, Coherent! Thanks, MBF! Thanks to course leadership and MBL staff!

Widespread cortical representations of innate behaviors in the mouse. www.biorxiv.org/content/10.1... Using the Diesel2p pacificoptica.com/diesel2p/, they found that "more directed and unilateral grooming movements had greater cortical associated responses than more stereotyped bilateral movements"

We will start gathering at about 3:00.

No more stitching artifacts. Just image the whole field-of-view, at high resolution, in one pass. The Ventana systems give submicron resolution over huge fields-of-view almost 10 square mm. At high speed. Cover a 3.2 mm x 3.2 mm area in 4k resolution in 0.26 s. pacificoptica.com/ventana/

Animals sense in complex environments, and neuronal responses to olfactory/scent stimuli can be shaped by recent history going back ~ 30 s. Here, Subramanian, Storace, et al. used the Cousa objective pacificoptica.com/cousa/ to neural activity in vivo. doi.org/10.1093/chem... #microscopymonday

Multinucleated giant cells (MNGCs) emerge as ovaries age, and are hard to study. Here, Converse, Pritchard, Duncan et al. used 2p imaging with the Cousa objective pacificoptica.com/cousa/ in their comprehensive study of age-associated MNGCs. #microscopymonday www.biorxiv.org/content/10.1...

This system has tons of fascinating tech— optics, detectors, software— so many scientists and engineers collaborated on this international project, enjoy the fruits of their talents!

Fantastic work (as always) from Che-Hang Yu and colleagues in Spencer LaVere Smith's lab. Very neat method to increase scan speed and/or FOV in 2p microscopy. Commercially available from @pacificoptica.bsky.social. I'd love to build this for a client at some point! www.biorxiv.org/content/10.1...

🚨THIS IS NOT A DRILL🚨We are 6 days away from the world's First Look at images from Rubin! #RubinFirstLook 🔭🧪 NSF–DOE Rubin Observatory will take a new 3200-megapixel image every ~40s, yielding ~20 terabytes of data every night! The deluge of data is about to begin 🌊

Riddle: When is an "optical invariant" is not so invariant? How can you get a larger field-of-view for free? No change in resolution or scan speed. No more stitching needed! For #MicroscopyMonday here's a new preprint to check out. 1/9

Scientists at work. This is a #ucsantabarbara collab with www.mbfbioscience.com Diesel2p pacificoptica.com/diesel2p/

Upgrade your 2p to 4k. We used to have to trade off resolution to get a larger field-of-view. Now, with Ventana, you don’t have to. Keep your resolution. Keep your frame rate. And get 4x the field-of-view. pacificoptica.com/ventana/

What’s new, etendue? Spencer LaVere Smith will be presenting new optics at the @optica.org conference in San Diego tomorrow.

Your yearly reminder to acknowledge the core facilities you use and their staff scientists in your papers.
