ACS-570-x – LED calibration standards for luminous flux and luminous intensity 100 Red LED Spectral radiant power / /% Spectral radiant power % The ACS 570 LED calibration standards for luminous flux and averaged LED intensity ILED-B are available in cool white (ACS-570-1) and the three basic colors blue (-3), green (-5) and red (-7). This covers the entire visible spectral range. Normally, the white ACS-570-1 is used for the calibration of all larger integrating spheres ISP and luminous intensity adapters LED-4xx from Instrument systems. Typical luminous flux values are 20 - 30 lm and the...

ACS-570-2x – UV LED calibration standards for radiant flux The ACS 570 UV LED calibration standards from Instrument Systems are available in three versions with typical peak wavelengths for UVC (on request), 305 nm for UVB (ACS-570-26), and 365 nm for UVA (ACS-570-28). The extremely low measurement uncertainties (k = 2) of only 3.5% in UVB and 2% in UVA are comparatively low as in the visible range, which is metrologically less challenging. UV-LED calibration standards can be used for monitoring and for the absolute calibration of special UV measurement equipment such as integrating spheres...

ACS 586/587 – LED luminance standards The ACS 586/587 are new, highly stable LED luminance standards. They support testing of all luminance meters on both filter and spectroradiometric basis. The radiation of the high-power LED is emitted into an integrating sphere with an inner diameter of 100 mm through a diffuser. The inner layer of the integrating sphere homogenizes further the radiation and emits homogeneous luminance through an opening of 25 mm in diameter. This structure ensures that the LED luminance standard has Lambertian radiation characteristics. The reference values, the...

02 \\ dvanced Technology behind A Advanced Standards ACU The ACU is a new compact control unit for ACS calibration standards from Instrument Systems. It contains a high-precision constant current source in a compact desktop housing in addition to a TEC controller for accurate temperature stabilization. The ACU has been developed for both laboratory and production use. The ACU is controlled by means of a computer via USB using the ACSControl software. Both, Windows 10 and OS X operating systems are supported. Moreover, the relevant program libraries (.dll and .dylib) are available for direct...

After completion of the short stabilization phase, the forward voltage and the temperature remain constant. The radiant power of the LED therefore remains constant over a long service life and the fast operational readiness saves valuable time. ACS 570 in application ACS 570 can be applied to monitor various systems. For luminous flux measurements with ACS 570 there are adapters available for all spheres manufactured by Instrument Systems. The adapters are universally applicable with all our LED test sockets. For averaged LED intensity measurements, the ACS 570 can be connected directly to...
