UV Laser

Spectra-Physics® (Santa Clara, CA), a Newport company, has introduced Talon 355-20, a high UV output power addition to its Talon family of Q-switched diode-pumped solidstate (DPSS) lasers. The new laser delivers >20 W UV power, wide-repetition-rate range of 0 to 500 kHz, and excellent beam profile and stability.

Using a Wide-Band Tunable Laser for Optical Filter Measurements

The concept of dense wavelength division multiplexing (DWDM) in fiber optic communication networks gained traction when optical amplifiers became available. Able to amplify an entire wavelength grid at once, they removed the need to first demultiplex, then convert every channel to an electrical signal, regenerate it, convert it back to an optical signal, and finally multiplex all channels onto a single optical fiber.

Implementing Color Machine Vision Inspection Systems

Color provides critical information that can improve the reliability of many machine vision inspection applications and make it possible to inspect many products that cannot be inspected in grayscale. Typical examples include ensuring that a tan rather than a taupe automotive interior component is installed, and checking the position of a black label on a black single-serving coffee cup.

High Performance, 1.5 µm, CW and Pulsed Fiber Lasers

There has been increasing interest recently in high power pulsed and CW fiber lasers sources in the 1.5 micron region. Operating at this wavelength has an advantage in eye safety when compared with 1 µm laser sources and also coincides with a window of atmospheric transparency.

Two-Axis Gear-Drive Gimbal

AMG-GR gear-driven motorized gimbals from Aerotech (Pittsburgh, PA) provide economical, high-accuracy elevation- over-azimuth positioning. The AMG-GR standard circular cells range from 100 mm to 300 mm in diameter. Cell mounting options include a centered (balanced) cell or a front-surface reflection option where the front of the optic is located on the axes of rotation. Special configurations can accommodate non-circular optics, cameras, sensors, and round optics larger than 300 mm in diameter. The modular design permits each gimbal mirror cell to be easily modified or replaced with different shaped cells to accommodate sensors or other asymmetrically-shaped payloads.
