Congratulations to Elizabeth Hillman, associate professor of biomedical engineering at Columbia Engineering, who implemented a high speed polygon scanner in a new 3D microscopy technology. SCAPE (swept confocally aligned planar excitation microscopy) uses a simple, single-objective lens imaging geometry that…
A suitable beam expander is used to adapt the source to the optical system. In an R&D project, multiple sources may be tested. Each source may have a different beam diameter so it is easier to use a zoom expander…
The high speed and high laser damage threshold of polygon scanners are required for many high power and Ultrafast / Ultra Short Pulse (USP) material processing applications. With pulse lasers operating at MHz rates, traditional galvanometer scanners are not fast…
The concept of laser paint stripping has been around for a long time. Laser ablation is attractive because it can avoid damage to the part caused by abrasive methods of paint removal and does not require the use of toxic…
Polygon scanners are most commonly running on Ball Bearings or self-generating Air Bearings. Ball Bearings work well from zero to 10,000 RPM. Ball bearings may be run at double that speed but the life will be reduced and grease misting…
Beam expanders are required in most laser systems to change the diameter of the incoming source to match the requirement of the optical system. In size restricted applications, it is desirable to use a compact beam expander but in most…
When an engineer designs a laser scanning system, a suitable beam expander is used to adapt the source to the optical system. The scanning system can take a long time to develop and may remain in production for many years. …
Many laser systems have a beam expander to change the diameter of the beam from the source to match the requirements of the optical system. Most beam expanders have two or three lenses to accomplish the task. While three lenses…
The Focal-piShaper 9_HP presents a new version of refractive focusing beam shapers optimized to operate with modern high power Ultra-Fast (picosecond & femtosecond) lasers. Optical design of the Focal-piShaper 9_HP is adapted to high pulse energy and provides reliable transformation…
This calculator makes it easy to compute polygon scanner / polygon scan head scan rate, speed of spot on the target and then compute the needed laser pulse rate based on spot size and required overlap. POLYGON SCANNER CALCULATOR Plug…
