To solve your needs, Marktech engineers will discuss with you:
Optimal drive current and temperature minimize degradation/ lifetime effects.
Forward current vs. ambient temperature:
Figures 1 and 2 show an example in which the current is derated to account for temperature. CREE technical data for LED lamps shows the permissible current values against temperature. Refer to this information when planning a new design.
The following example describes how to derate for temperature when designing:
Figure 1 – Specified by design (25 mA) exceeds permissible value at 70C high temperatures
Figure 2 – Specified by design (25 mA) is within permissible value at 70C high temperatures
Characteristically, the luminous intensity of LEDs gradually decreases over the life of the LED. The rate at which the luminous intensity falls varies according to the material used and the forward current at which the LED is driven. The more significant the current, the greater the diminution of luminosity. Thus, when setting the forward current of the LED lamp, do not determine the setting solely from the temperature characteristics, as in the above example, but consider also longevity characteristics. An effective way of improving the longevity characteristics is to set the forward current of the LED lamp relatively low.
Spatial radiation characteristics: The lens or lens cap on an LED determines the angle-dependent output power obtainable. Lens characteristics also determine intensity peaks and coverage areas. Marktech products provide an excellent choice in beam angle, which must match the application and sensor needs. Marktech analyzes these radiation patterns using goniometer equipment.
Luminous intensity and directional characteristics Relationship between luminous intensity units and directional characteristics. Luminous intensity is measured in candela (cd), and the radiance is measured in watts/steradian (W/sr). One steradian is the solid angle at the center of a one-meter-radius sphere subtended by a square meter of surface area. The steradian is a metric unit. The radiance of light is the amount of luminous flux propagated in a given solid angle or the amount of incident. Hence, as the figures below show, the narrower the directionality of an LED lamp, the higher the luminous intensity of that lamp.
Hence, for an LED lamp of a given directionality, the higher the chip’s emission efficiency, the higher the luminous intensity.
Application Viewing angle
High-brightness LED information panel 15° to 30°
Signal applications 8° to 30°
Low-Brightness LED information panel 30° to 120°
Narrow-Direction indicator 30° to 60°
Wide-Direction indicator 60° to 120°
Automotive stop lamp 20° to 50°
Automotive dashboard narrow directionality 20° to 60°
Automotive dashboard wide directionality 60° to 120°
Marktech can custom tailor the viewing angle of an LED by flat, dome, or ball lens. A flat lens provide a wide angle or broad dispersion. Dome lensed LEDs have a narrower directionality or small viewing angle compared to flat lensed LEDs. A ball lens produces the narrowest beam.
Constructed with FR-4, metalcore, or ceramic material, Marktech’s ring/chip offerings range from 280nm in the UV range, though visible to near IR; white light ring options can be made with color temperatures ranging from warm (2600K) to cool (10000K). Emitter, detector chips–or a combination of both–can be included in custom light ring packages. In most cases, Marktech can test to plus or minus 1 nanometer. Their size offerings range from 4mm in diameter to any required size.
Smaller-size light rings are typically manufactured with COB [chip on board] technology; however, standard surface-mount components such as 0805, 1206, and PLCC-type packages are also available, depending on the optical performance required.
Pulse oximeter: Oxygen and pulse rate monitoring
Typical medical physicals now include quick and reliable readings of patient oxygen levels. Due to the low cost of access to the equipment, these findings can be duplicated with home monitoring. Your blood’s oxygen levels are easily determined by a simple pulse oximeter, which uses two different LED emitter wavelengths. Oxygenated blood tends to absorb light at 660nm; deoxygenated blood absorbs light better at 905nm. The saturated peripheral oxygen level from your fingertip is quickly determined by making measurements and interpreting the results using Beer-Lambert’s law.
Design, purchase, and modify LED-sorting equipment to bin LED products into selected chips that are tighter than +/—1nm.
Ultraviolet LED emitter light curing is now used for applications ranging from dentistry to guitar finishes, including automotive, telecommunications, electronics, graphic arts, glass, and plastic decorating. Inks, coatings, and adhesives cured with UV LED light have dramatically improved physical properties. Traditional curing used highly inefficient and environmentally objectionable mercury lamps that could damage the subject matter if misapplied. UV LEDs, on the other hand, are highly efficient and offer a longer-life alternative to standard bulbs. Heat output is easily controlled with LEDs while lowering the time needed to cure, reducing the potential for damage to the cured object.
Marktech can optimize the emission wavelength for camphor quinone (CPQ) and other alternate materials used as the curing photoinitiator. Packaging can be optimized for access to, for instance, small dental probes optimized for patient use.

Design, purchase, and modify equipment to sort LEDs for power output with selected/consistent binning.
Short wavelength infrared (SWIR) and mid-wave infrared (MWIR) LEDs are the latest additions to Marktech’s broad lineup of light-emitting diodes. Marktech Optoelectronics is one of only a handful of manufacturers that supply emitters in the extended wavelength or SWIR range. Available in various through-hole and surface mount packages, SWIR emitters satisfy a growing need for high-speed light emission in ranges not easily seen by standard detectors and are also used for material and chemical analysis.
Medical, security, military, communications, industrial, analytical, metallurgy, power generation, and agriculture.
The rapidly growing market for SWIR includes applications such as produce inspection, security, surveillance, anti-counterfeiting, spectroscopy, moisture analysis, biomedical biofluorescence, blood chemistry analysis, night vision, safety equipment, currency validation, fiber optics, and silicon wafer inspection systems.
SWIR LEDs and detectors can help realize noninvasive imaging methods, such as optical coherence tomography (OCT) systems. These systems utilize SWIR to exploit the low scattering properties of >1ÎĽm light to see the previously unreachable, thick parts of the cornea.
Marktech’s standard product offerings include through-hole and surface-mount packages with wavelengths from 1050 to 2600nm and operating currents ranging from 20mA to 350mA for high-power applications. Higher mid-wave infrared (MWIR) wavelength LEDs with ranges up to 4300nm are available in specific package types. MWIR LEDs are vital in methane, carbon dioxide, and other gas analyzers.
The Marktech extended wavelength standard SWIR package offerings include our proprietary ATLAS hermetic SMD, TO-46 flat, TO-46 lens, TOPLED PLCC4, SMD 1206, SMD 1206 Lens, and SMD high-power black. Custom package options are also available.
