BTS256-LED-UV
Compact BiTec spectral measuring UV LED Tester for the Measurement of Radiant Power of Single UV LEDs
- Innovative implemented small integrating sphere with cone-shaped measurement port
- Plug & Play UV LED Testing directly on PCB
- UV LED based auxiliary lamp for substitution correction (self-absorption correction)
- Measurands like: Spectral radiant power, peak intensity and wavelength, spectral distribution, etc.
The optical specifications of LEDs must commonly meet very high tolerance requirements even for non-specialist applications such as general and automotive lighting. This is often a problem since the manufacturing tolerances of UV LEDs can be higher than those permitted in the applications. The tolerance limits offered by UV LED manufacturers’ intensity and spectral peak wavelength are only applicable if the operating conditions are similar to those in the binning tests or sometimes the range of the bins is simply too large for an application. Therefore, manufacturers incorporating UV LEDs into their products require devices that can accurately measure the precise in-situ optical performance of UV LEDs.
Compact UV spectroradiometer and UV LED Tester
The compact BTS256-LED-UV enables you to conveniently measure the UV radiant power and spectral distribution of single UV LEDs. One special feature is the conical measurement port of the device. The ability to perform measurements of onboard UV LEDs in seconds makes it possible to also include thermal effects in the measurement. The device is therefore ideal for inspection of incoming UV LED products as well as the quality control in production processes. It can also be very useful in the design department.
The BTS256-LED-UV comes in a compact aluminum housing and offers all functions that are necessary for precise measurements.
Traceable Calibration
One essential quality of measuring devices is their precise and traceable calibration. Calibration of the BTS256-LED-UV is performed in Gigahertz-Optik’s ISO/IEC 17025 calibration laboratory that is accredited by DAkkS (D-K-15047-01-00) for the spectral responsivity and spectral irradiance according to ISO/IEC 17025. The device has two calibrations: one is done using a specially developed reference lamp offering 2pi illumination which enables precise measurement of the luminous flux of diffusely emitting UV LEDs. The second calibration is for sources that have narrower illumination characteristics.
Options for the BTS256-LED-UV
- Software-Development-Kit to enable users to integrate the device in their own software
- Extension to the BTS256-LED Plus Concept (for other optical quantities) using other components
1) BTS256-LED-UV housing 2) 50 mm integrating sphere with synthetic coating 3) Conical measurement port 4) Precision bayonet mount 5) Test LED on a circuit board (device under test) 6) Remote-controlled auxiliary lamp 7) BiTec sensor with Si photodiode, CMOS diode array spectrometer and shutter 8) Microprocessor 9) USB 2.0 interface
