Accessories for particle visualization
Assembly cleanliness is of crucial importance for ensuring process and product quality. In VDA Volume 19 Part 2, which focuses on technical cleanliness in assembly, the cleanliness specification of a component, assembly or assembled system is the starting point for assembly cleanliness. The aim of all measures is to prevent particles from being introduced during assembly and the associated processes that should not be present in the component according to the cleanliness specification.
Since a wide range of cleanliness requirements can be derived from the "environment" influencing factor in particular, VDA 19.2 divides the spatial environment into different cleanliness areas with different cleanliness levels. In order to objectively evaluate the cleanliness of these areas and, if necessary, improve it with suitable measures, particles must be reliably detected and quantitatively evaluated. At CleanControlling you can obtain professional measuring equipment for particle visualization and visualization of defects on smooth surfaces.
Special lamps for particle visualization
The particle visualization lamp PVL 2 was developed for particle visualization as part of the regular visual inspection of contaminants in the cleanroom. It emits UV light (365 nm wavelength) and thus makes fluorescent particles visible on all surfaces. Typical inspection areas include cleanroom surfaces made of stainless steel, plastic and aluminum, as well as cleanroom clothing and wiping cloths.
The PVL 3 model is capable of visualizing both fluorescent and non-fluorescent particles. Thus, it enables particle visualization even in containers, machines, process chambers, etc. As with the PVL 2, fluorescent particles are made visible with UV light (365 nm wavelength), while non-fluorescent ones are visualized by strong white light. Switching between UV and white light is done by pressing a button directly on the instrument. If the PVL 3 is supplemented with a light guide (the required attachment is included), surfaces can be viewed and evaluated in grazing light.
Both lamps ensure reliable particle visualization so that cleaning processes in production can be optimized without the need for a measuring device. The particle visualization lamps are H2O2 and disinfectant resistant and water impermeable. The power supply is provided by a rechargeable Li-Ion battery with a burning time of approx. 1.5 hours. The battery is charged to a charging cradle with a power supply unit, both of which are included in the scope of delivery, as are other accessories.
To protect the eyes, protective goggles should be worn during particle visualization under UV light, which are also included.
For the inspection of process chambers, machines, equipment and materials, CleanControlling offers a highly efficient inspection lamp. It is characterized by particularly bright light (maximum luminous flux: 140 lm) and a long burn time of up to 5 hours. The illumination range of the inspection lamp is up to 120 m, the power supply is provided by an AA battery (1.5 V). The lamp allows infinitely variable focusing and glare-free illumination and is also very compact and, with a weight of just under 80 g, particularly light.
Measuring magnifier for particle sizing
The measuring magnifier offers a particularly flat field of view and corrections for achromatic and astigmatic fields. The coated lens system with focus ring allows the user to focus the scale and instantly determine the size of particles using the integrated crosshair measuring scale (15 mm). The measuring magnifier provides 10x magnification and comes complete with crosshairs and storage pouch.
