PSMPPhotoScribe Technologies offers this brief video demonstrating a complete turn-key marking solution that the company delivered to a customer for marking pharmaceutical tablets. The laser system is designed to mark on the fly as parts pass beneath the laser.

Keyence’s VK-X 3D laser scanning microscopes combine the capabilities of an optical microscope, profilometer and an SEM, according to the company.


beam profilingMost people working with lasers today are trying to do something with the light beam, either as the raw beam or, more commonly, modified with optics. Whether it is printing a label on a part, welding a precision joint or repairing a retina, it is important to understand the nature of the laser beam and its performance.

During the 7th International Conference on MicroManufacturing in March, conference co-chairs Jian Cao and Kornel Ehmann, along with a few of their students, provided an overview of their research and work stations at the university's micromanufacturing lab.

Small Car at Vienna thumbA 285µm-long racecar has been fabricated in record time via ultrahigh-precision 3-D printing at Vienna University of Technology.

Check out this cool video of thermal laser forming performed at the Penn State University’s Applied Research Laboratory.

LaserStarOct. 31, 2011—LaserStar Technologies, Riverside, R.I., recently demonstrated a microweld using the company's 7700 Series laser system with Universal Jig, which is said to be ideal for a wide range of unique and custom integration applications for metal joining, complex assembly and repair.

Dec. 13, 2010—Slovenia researchers recently demonstrated full 3-D tunable lasing in laser dye-doped cholesteric liquid-crystal (CLC) microdroplets from 15µm to 50µm in diameter—a first, according to an article in the Dec. 10 issue of Optics Express, an international online journal of The Optical Society.

Oct. 8, 2010—In the video below, Raydiance Inc.'s ultrafast Smart Light laser ablates a kitchen match—without lighting it. The Smart Light is suited for medical device manufacturing, medical therapies, biosciences, industrial laser processing and defense markets.

Sept. 27, 2010—Control Micro Systems, which sells laser systems for marking and other applications, earlier this year posted a video to YouTube demonstrating its desktop laser marking ability. The Winter Park, Fla., company filmed its desktop laser marking 2-D codes into the slots on the head of a small screw.
