Marktech's High Reliability 650nm Point Source LED Improves Sensing Accuracy
Marktech Optoelectronics has added 650nm wavelength to its high accuracy Point Source LED series. An unobstructed, narrow beam of light output and newly improved spectral bandwidth are key features to the Point Source product line. This series of LEDs is ideally suited for critical sensing applications including Encoders, Linear or Edge Positioning Sensors and Medical sensing equipment. Customers utilizing the Point Source series in these applications have been able to substantially improve the performance of their products especially at higher speeds.
The unobstructed, radiated beam pattern is made possible by masking the die and relocating the topside electrode. By eliminating the "Dark Spot" typically associated with conventional LEDs, the Point Source LED series yields far more accurate results in sensing applications.
For applications using thin fiber optic cable, the unobstructed die and narrow beam allow for the fiber to be positioned in close proximity to the Point Source chip for superior accuracy. Additionally, a "Near Parallel" beam of light can be achieved with an internal ball lensing option mounted to the top of the LED die.
Outside of standard product offerings, Marktech has the in house ability to customize die and component packaging depending on the customer's requirements. Die aperture windows are available up to 200um. Standard packaging options include metal can TO-18 and TO-46 metal can types as well as miniature surface mount ceramic versions. Additionally, there are a number of lensing options available depending on the beam output desired.
