  2. Photopolymer - Wikipedia

    en.wikipedia.org/wiki/Photopolymer

    Acrylated urethane oligomers are typically abrasion resistant, tough, and flexible, making ideal coatings for floors, paper, printing plates, and packaging materials. Acrylated polyethers and polyesters result in very hard solvent resistant films, however, polyethers are prone to UV degradation and therefore are rarely used in UV curable material.

  3. Acrylonitrile styrene acrylate - Wikipedia

    en.wikipedia.org/wiki/Acrylonitrile_styrene_acrylate

    It is used for general prototyping in 3D printing, where its UV resistance and mechanical properties make it an excellent material for use in fused filament fabrication printers, [1] particularly for outdoor applications. ASA is also widely used in the automotive industry.

  4. Photoresist - Wikipedia

    en.wikipedia.org/wiki/Photoresist

    The primary properties of the photoresist are resolution capability, process dose and focus latitudes required for curing, and resistance to reactive ion etching. [ 14 ] : 966 [ 15 ] Other key properties are sensitivity, compatibility with tetramethylammonium hydroxide (TMAH), adhesion, environmental stability, and shelf life.

    Figure 1: Simplified schemes of the Variable UV-Vis detector compared to PhotoDiode Array detector. In the Variable UV-Vis the entire optical bench is located before the flow cell whereas in the diode array the flow rate is positioned before the main optical bench. A schematic of the optical systems is shown in Figure 1.

  6. Plate reader - Wikipedia

    en.wikipedia.org/wiki/Plate_reader

    Plate readers, also known as microplate readers or microplate photometers, are instruments which are used to detect biological, chemical or physical events of samples in microtiter plates. They are widely used in research, drug discovery , [ 1 ] bioassay validation, quality control and manufacturing processes in the pharmaceutical and ...

  7. Ultraviolet index - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_index

    The ultraviolet index, or UV index, is an international standard measurement of the strength of the sunburn-producing ultraviolet (UV) radiation at a particular place and time. It is primarily used in daily and hourly forecasts aimed at the general public.

  8. Photometer - Wikipedia

    en.wikipedia.org/wiki/Photometer

    Historically, a photometer was separate from the camera and known as an exposure meter. The advanced photometers then could be used either to measure the light from the potential picture as a whole, to measure from elements of the picture to ascertain that the most important parts of the picture are optimally exposed, or to measure the incident ...

  9. Automatic meter reading - Wikipedia

    en.wikipedia.org/wiki/Automatic_meter_reading

    With touch-based AMR, a meter reader carries a handheld computer or data collection device with a wand or probe. The device automatically collects the readings from a meter by touching or placing the read probe in close proximity to a reading coil enclosed in the touchpad. When a button is pressed, the probe sends an interrogate signal to the ...
