A coupling device for an optical waveguide includes an optical waveguide connection for a first optical waveguide. The coupling device includes an optical filter arranged in a beam path between a laser light source and the optical waveguide connection which reflects light of a first wavelength range or a first polarization direction and transmits light of a second wavelength range or a second polarization direction.

A filter device (1) according to figure 1 for suspended materials (2.3) having a particle size of 400 pm to <=500 microns in flowing fluids (2.2) having a volumetric flow rate of 10-2 mL / sec to 105 mL / sec, comprises a device (2) for reduction (>99%) in the specific particle count (N / Vt) of suspended materials (2.3.1) with particle sizes from 1 nm to 50 nm and of suspended materials (2.3.2) with MPPS particle sizes from >= 200 nm to <= 400 nm by means of an energy input from 0.25 W to 1 kW by means of ultrasound waves stabilized with electronic feedback loops and their harmonics (2.4.2) at a frequency of 1 kHz to 800 MHz and a power level of 40 to 250 dB in the fluids (2.2) or in bodies (2.6) attached thereto, so that fluids (2.2.1) with suspended materials (2.3.1) and / or with suspended materials (2.3.2) having a specific particle count (N / Vt) <= 20% and with suspended materials (2.3.3) having particle sizes of >=50 nm to <= 200 nm and / or with suspended materials (2.3.4) having particle sizes of >= 400 nm to >1000 nm having in each case a specific particle count (N / Vt) can be obtained to >= 80%, further comprising a flow pipe (2.1) having a wall (2.1.1) which, on its outer side (2.1.1.1), its inner side (2.1.1.2) and / or in the wall (2.1.1) has pairs of mutually opposite exciters (2.4.1) of longitudinal waves and their harmonics (2.4.2) and / or reflectors (2.4.3) opposite the exciters (2.4.1), through which pipe the fluids (2.2) and (2.2.1) can flow, a delivery device (2.5) for the fluids (2.2) and (2.2.1) and a connection (2.7) of the flow pipe (2.1) to a filter (3) of a smallest filterable particle size of 50 nm to 1000 nm, which keeps the specific particle counts (N / Vt) of the suspended materials (2.3.1), (2.3.2), (2.3.3) and (2.3.4) in the filtered fluids (2.2.2) to below the detectable limit or to 0.1%, where N = particle count, V = volume [m3], t = time [h], and the indicated percentages being in relation to the respective specific start counts (N / Vt) of the respective suspended materials = 100%; and filtration method, uses and equipment and plants with filter installations (1).

The invention relates to a washable device (1) for personal grooming, in particular a hair removal device (2), for example to use as a depilator (3) and / or razor (4). The invention provides that the device (1, 2, 3, 4) is coated at least partially with paraffin. The invention further provides that the device (1, 2, 3, 4) contains antibacterial substances. The invention relates also to a method for the production of components (5, 6, 7, 8; 9) of a device (1, 2, 3, 4) for personal grooming. The invention provides that the components (5, 6, 7, 8; 9) are dipped in a melted liquid made of paraffin and / or are sprayed with the melted liquid, or that the components (5, 6, 7, 8; 9) are sprayed with a paraffin solution or are treated in a drum with solid paraffin.
