BLINK High-Speed Focuser
Patent-Pending Design is Compact and Blazingly Fast
“Blink and you’ll miss it… 30 times!”
Nutfield Technology’s BLINK High-Speed Focuser offers blazingly fast focusing performance in a compact, maintenance-free package. Our patent-pending ultra-stiff air bearing design results in a friction-free bearing that offers stable servo bandwidths in excess of 500 Hz. The BLINK High-Speed Focuser is capable of continuous operation with a 50G peak sine wave, and its ultra low moving mass design (28 grams with lens) minimizes reaction forces. Its high efficiency motor complements the air bearing performance allowing for 100% duty cycle 1 mm focusing moving at less than 12 watts RMS.
Nutfield Tech’s initial release features a 13mm clear bore and 13mm of stroke. The BLINK High-Speed Focuser can be fitted with a variety of standard 1/2″ diameter lenses to suit any application. It’s also available as either a stand-alone focuser or integrated with Nutfield Technology’s popular post-objective scan heads, like Nutfield Tech’s 3-axis Contour.
With only one moving part, BLINK offers exceptional reliability and service life when compared to traditional taut band actuators.
