The Latin word Acies (ACS for short) is defined as the full attention of one's sight and senses, as directed towards a particular object. Based on that description, what an appropriate name for nac's new MEMRECAM high speed camera system!

Additional Product Details


Boost Mode/Boost4 Mode
Boost Mode*1 combines nac's unique sensor technology with a proprietary signal processing method to increase frame rate and resolution with little or no image degradation. This is a powerful tool for any application requiring higher frame rates and larger resolutions.

Boost up Frame Rate
@1280 x 800 pixels
Normal Mode: 14,000 fps -> Boost Mode: 25,000 fps -> Boost4 Mode: 50,000 fps

Boost up Resolutions
@50,000 fps
Normal Mode: 1280x224 pixels -> Boost Mode: 1280x448 pixels -> Boost4 Mode: 1280x896 pixels

*1 Boost Mode is currently available on monochrome models only.

High Light Sensitivity ISO 100,000
All ACS series cameras are equipped with state-of-the-art CMOS sensors featuring extremely high light sensitivity (monochrome ISO 100,000). Even in low light environments, the ACS produces bright, dynamic, and crisp images, making the ACS-3 M16 an ideal tool for high magnification and microscope applications – no need for bright lights on heat sensitive subjects.




PC-less Operation
No PC, no problem! The ACS series V-PAD offers a beautiful HD viewfinder with full touchscreen camera control. Whether you are out in the field or in a restricted area where PC control is not practical, the V-PAD allows for full control of the ACS camera – from setup, to capture, to review, to saving – all with an intuitive touch screen interface.

Compact Standalone System
The ACS-3 provides many of the same features and benefits of its high-performing predecessor, the ACS-1, but in a smaller, lighter form factor. Compared to prior nac models like the MEMRECAM HX-3, the ACS-3 is a full 40% smaller and 30% lighter. The ACS-3 is a mobile and reliable system for almost any high-speed camera application.

Easy Synchronization of Multiple Cameras
With both SYNC-IN and SYNC-OUT connectors on its rear panel, the ACS offers incredibly simple and accurate camera synchronization. ACS cameras can be synchronized to each other using a single sync cable. No trigger distribution boxes or external sync devices are required.
