Discover the performances of the P-OSL technology
The former generation of Auto-Reader were based on Continuous-Waves Optically Stimulated Luminescence (CW-OSL) technology. Those readers (the A200 and A500 InLight readers) are no longer manufactured since April 2020. LANDAUER continue to support and service these units until April 2025.
The OSLR reader uses a novel integrated and compact Optical Engine that utilizes a High-Powered Light Emitting Diode (LED) and Pulsed Optically Stimulated Luminescence (P-OSL) technology to achieve better separation between the optical stimulation spectra (green region: λ=532 nm) and luminescence emission spectra (blue region: λ=420 nm), resulting in superior signal to noise performance in comparison to CW-OSL methods that rely on optical filtration alone to achieve this separation.
| The advantage of the P-OSL method is that a higher signal-to-noise ratio can be achieved, resulting in better overall performances. |
Which solutions to update your OSL reader?

Three versions are proposed to read INLIGHT dosimeters using LANDAUER OSL technology.
OSLR readers perform both reading and annealing process with higher throughput making it quick and easy to process results. The readers OSLR 1, 50, OSLR 250 and OSLR 700 adapt to the number of monitored participants in your organization. The readers can easily be upgraded to a higher loader capacity to accommodate evolving needs.
OSLR is upgraded to read the new ONYX OSL ring and TOPAZ OSL lens of eye dosimeters which use the new generation of OSL sensor: MP7 sensor.

MP7 OSL sensor
Ring and lens of eye dosimeters use a novel near tissue equivalent MP7 OSL sensor.
The dose is measured using the OSLR readers.
