Industrial 50W Picosecond Laser

RPMC Lasers (O’Fallon, MO) has introduced an industrial 50W picosecond laser suitable for manufacturers who need to drill or cut thin materials to produce components that should not be subjected to heat. Because the RAPID lasers have such short pulses, heat generated by the beam will not migrate into heat-affected zones. The result is a laser process known as cold micromachining that generates no burrs or splatter. The picosecond lasers are effective on materials under 1 mm in thickness, and offer removal rates as high as 30 mm3/min. The lasers are effective on all materials used in semiconductor, electronics, solar cell, aerospace, automotive, medical, microfluidics, micromold technology, etc. They also feature 50W average power with

Variable Focus Industrial Laser Module

Photonic Products (Hertfordshire, UK) has released a new range of variable focus industrial laser diode modules that offer high boresight accuracy of The modules also feature either a standard elliptical output beam or line generating optics with a 45°, 60°, or 90° full fan angle line to give straight-line precision without bowing. The modules have optical output powers from 0.95 mW to 27.50 mW, operating voltage of 5V DC regulated ±10% and operating temperature from -10 to 50°C, and are static, surge, and reverse polarity protected and RoHS compliant. Electrical connections are made via an industrial screw-on connector or 2.5 mm jack.

Hi-Speed DM37 Deformable Mirror

ALPAO (Biviers, France) has developed the Hi-Speed DM37, with optimized temporal response, large stroke, and high linearity. Designed for applications requiring large corrections with a small optical beam, this entry-level mirror is interfaced with Matlab, Labview, and C/C++. Advanced users who wish to write their own drivers can benefit from the LEDBOX (option) to simulate the ALPAO Hi- Speed DM37. The DM37 has a clear aperture size of 7.5 mm and an operating temperature of 15-35°C. It features 37 actuators, with 1.5 mm distance between each actuator.

Continuously Variable Apodizing Filters

Edmund Optics (Barrington, NJ) has introduced continuously variable apodizing filters designed to eliminate undesirable intensity variations and create an even illumination profile in optical systems. The Bull’s Eye type filter features a high optical density in the center that decreases continuously to an uncoated edge in order to flatten the intensity profile of Gaussian beams. The Reverse Bull’s Eye type filter features a high optical density coating on the edge of the filter, which increases continuously to an uncoated center. EO’s standard Bull’s Eye type filters are available in 25- and 50-mm diameters with end densities of 1.0 and 2.0. They are manufactured using a B270 substrate to a dimensional tolerance of +0.00/ -0.20, a surface quality of 60-40, and a thickness of 1.50 +0.10. The filters are suitable for a design wavelength range of 400-700 nm.

Fiber-Coupled, Multi-Bar Module

A fiber-coupled, multi-bar module from DILAS (Tucson, AZ) delivers 300W through a cladding mode free QBH high-power 200-μm core diameter fiber with a low numerical aperture of 35%. The modules are packaged in up to 10-bar configurations and designed based on industry-standard conductively cooled bars, which are optically stacked and polarization-coupled. The product requires only industrial water for cooling. The modules have demonstrated a lifetime greater than 10,000 hours at a 300W CW operating condition. Custom wavelengths are available upon request. They are designed for direct diode applications as well as fiber and solid-state laser pumping.

Auto Focus Modules for CCD/CMOS Cameras

New Scale Technologies (Victor, NY) has introduced custom auto focus modules that install directly on board-mounted cameras and accept standard threaded lens assemblies. The compact lens motion module uses New Scale’s tiny SQUIGGLE® motor, TRACKER™ position sensor, and integrated electronics to provide high-resolution, closed-loop control. These components are combined with precise mechanical guidance in a robust polymer housing only slightly larger than the optical lens assembly. The module features a stroke of >2 mm, lens mass of up to 10 g, velocity of 7 mm/sec, and position resolution of 0.5 μm. The encoder type is a hall sensor array and incremental (absolute over 2 mm).

Scalable SPM Array for Large Area Detection

The SPMArray from sensL (Cork, Ireland) is the first four-side scalable low-light-detecting silicon photomultiplier array for use in markets such as medical imaging, homeland security, radiation detection, analytical instruments, and high-energy physics. The four-side scalable low light detector features a small form factor that makes the SPMArray suitable for weight and space constrained handheld radiation detection and identification systems. The package used in the SPMArray is not impacted by large magnetic fields and is designed to be magnetic compatible up to 3 Tesla.
