An infrared windows is an engineered optic designed to permit infrared inspections of electrical components located within switchgear enclosures.

The PowerMeasuringModule is suited to many other applications in automated manufacturing with solid-state lasers – not just in macro-processing, but also micro-processing. The PMM's field of application can optionally be extended to low average powers as well as pulsed beam sources.

Conclusion: The impact of the updated definition on the frequency of PH and PAH in our cohort was greater than previously reported, which may be caused by the difference in screening strategies for PAH.

The PowerMeasuringModule is operated solely via the system controller. The sequence of a power measurement can be divided into three stages:

DisplayThe measurement results are displayed by the user autonomously at the system controller level. Data transfer is adapted to the fieldbus system used.

Fast measurement sequenceWhen the PowerMeasuringModule is integrated into a industrial robot manufacturing set-up, the aim is to achieve the shortest possible clock cycle when measuring. In order to reduce the measuring duration, the standstill time of the robot can be reduced to just the irradiation period of the PowerMeasuringModule.

The PowerMeasuringModule is suited to users who have specialised in manufacturing with lasers. The system is used frequently in automotive manufacturing. Car bodies are frequently welded with robot-controlled solid-state lasers (Nd:YAG-, fibre, disk or diode lasers).

Methods: Patients with SSc admitted between 2015 and 2019 and who underwent right heart catheterization (RHC) were included. The frequency of PH and its subgroups based on the hemodynamic definitions of both 2015 European Society of Cardiology/European respiratory Society (ESC/ERS) PH guidelines and 6th WSPH was compared.

The measurement result is independent of the beam dimension and the beam position. The absorber cools via thermal conduction to the surrounding air. This restricts the measurement frequency of the system. The plant controller can query the absorber temperature at any time and determine the new irradiation period.

Entry into automated power monitoringThe PowerMeasuringModule (PMM) is a robust laser power measurement system that determines optical power directly in the production zone. Due to the fieldbus interface, the PMM can be easily integrated into equipment controllers – various systems are available. Fully automated measurements can be carried out and documented due to the direct coupling to the machinery controller. This creates the basis for beam monitoring during processing – an essential component of quality assurance in manufacturing with lasers.

Objective: Pulmonary hypertension (PH) is a one of the major causes of death in patients with systemic sclerosis (SSc). In this study, we investigated the impact of updated hemodynamic definition proposed by the 6th PH World Symposium (6th WSPH) on the frequency of PH and its subtypes in patients with SSc.

Results: Of the 65 patients with SSc, 23 (35.4%) had normal mean pulmonary arterial pressure (mPAP), 20 (30.8%) had mildly elevated mPAP (21-24 mm Hg), and 22 (33.8%) had PH [pulmonary arterial hypertension (PAH) (n=16, 24.6%), group 2 PH (n=5, 7.7%), group 3 PH (n=1, 1.5%)] according to the 2015 ESC/ERS PH definition. Based on the updated criteria, 7 (10.8% of total cohort) additional patients were reclassified as having PH [PAH (n=3), group 2 PH (n=3), group 3 PH (n=1)].

The PMM has received an upgrade and is now available as the PMM AP3s series. The designation AP3s stands for the following improvements:

The PowerMeasuringModule measures the laser power calorimetrically. The absorber is irradiated by the laser for a defined period. With the heat capacity of the test body, the temperature increase and the exposure time, the optical power is calculated in a few seconds. The exposure time measurement increases the reliability of the results.
