Visible and infrared LED sensor product maker Marktech Optoelectronics of Latham, NY, USA, whose capabilities span wafer growth through finished packaging and custom solutions, has introduced the latest in its series of high-power 950nm LED emitters, with typical power output up to 25mW.
Optimized for optical switches and sensors, the MTE9460 series is available (through distributor Digi-Key) in six standard packages - miniature ceramic packages (MTE9460MC and MTE9460CP), plastic SMD (MTE9460MT), TO-18 metal can (MTE9460WC) and plastic domed and flat top (MTE9460N1 and MTE9460N2) - with varying viewing angles and power outputs.
"This LED series yields superior results in critical sensing and scanning applications," claims chief technology officer Vince Forte. "As an example, many night-vision and surveillance/security cameras use IR LEDs to illuminate an area, making it visible in total darkness. These higher-power LEDs allow a greater area to be illuminated and create clearer pictures," he adds.
Another use for LED emitters is machine vision systems. "Our precision die placement ensures the highest quality and reliability, as well as extreme accuracy in high-speed applications," says Forte. "Faster testing speeds and higher-resolution analysis is a continual requirement for machine vision systems," he adds. "The higher output signal and low noise level of our 950nm LEDs ensures a more accurate reading."
Marktech also offers an extensive LED sensor product lineup targeted at industrial markets, specializing in high-accuracy applications. The MTE9460 series die, which utilizes the latest chip technology to achieve these high-power readings, can be configured into a number of TO can and lens standard options based upon application needs. In addition, Marktech can offer a variety of COB or custom array packaging.
