BLINK High-Speed Focuser Chapter 1: Safety Chapter 1 Safety Warning: Laser Radiation Although the unit does not emit radiation, it does redirect laser radiation emitted from other devices. Operators must follow all safety precautions provided by the manufacturer of any associated laser devices. -
Page 6: Chapter 2 Introduction
The BLINK High-Speed Focuser (US Patent 11,090,761) is designed to dynamically map a focal correction onto the laser beam. When a focusing lens or reflective optic is mounted in the BLINK focuser, it translates linearly at high frequency with high precision using the built-in optical position detector. In laser marking applications, the focuser adjusts the effective focal point of a galvo scanning system as a function of the mirrors’... -

3.6 Mounting a Lens BLINK units without a bonded optic have a Ø12.7 mm lens cell to accommodate an optic with a thickness of 1.00 - 3.35 mm. A non-bonded lens will have a clear aperture of Ø11 mm. The unit includes an SPB05 spanner bit required to change lenses. - Page 11 BLINK High-Speed Focuser Chapter 3: Setup Caution: Risk of Damage Failure to use the supplied stabilizer wrench when changing an optic may result in inadvertently twisting the stator and damaging the flex circuits. The stator should always be stabilized prior to adjusting an optic.
