Who we are


The company OBLF GmbH was founded with the aim of taking up the tradition of developing high-precision measurement systems. The first result of our endeavours was the ES 750 spark spectrometer in 1975. This industrial computer-based system featured the fastest spark generator (500 Hz) of the time.


The launch of the ES 750-15 extended our range of spectrometers. This model provided the special feature of combining a voltage/frequency converter (VFC) for converting photomultiplier signals with an OBLF-developed single-board computer.


Our series production was extended by the addition of a semiconductor-controlled 1000 Hz spark generator and a high-performance microcomputer system.


Conversion to an IBM-compatible, PC-based platform for equipment control and data logging purposes.


Market launch of the RS 1000 spectrometer, a new model series. A very compact spectrometer with ideal attributes for routine operation.


Patent granted for our pulse purging system for the spark chamber.


By integrating a microprocessor, the semiconductor-controlled 1000 Hz spark generator was turned into to a digitally generatable GDS discharge unit.


Market launch of the GISS data logging system. In combination with the GDS spark generator, this process elevated the field of spectroscopy to a new plane. This innovation was integrated into a new model named QSG 750.


Extension of the usable spectral wavelength range to 100 nm. This enabled the spectrometric analysis of ultra-low carbon (ULC) concentrations.


Market launch of the multi-matrix system VeOS. OBLF introduced in this high-end, solid state detector based OE spectrometer a new, exclusively for OBLF developed line sensor. The VeOS analyses from 130 up to 800nm.


Introduction of a double electrode spectrometer. The feature called ULB reduces the analysis time by a factor of 2.


The spectrometer generation II of GS 1000-II, QSN 750-II and QSG 750-II was introduced including a complete new designed read-out electronics. Hybride spectrometer using PMTs and sensor lines are now available.


The model VeOS is first able to calculate inclusions based on single spark emission spectra.
