The new TSL2591 family of digital light sensors from ams offers low-light sensitivity down to 0.000377 lux. With a wide 600M:1 dynamic range up to 88,000 lux (bright sunlight), the TSL2591 device ...

Graphene has many properties, but it does not absorb light very well. To remedy this, physicists resort to embedding a sheet of graphene in a flat photonic crystal. Scientists now demonstrate that by ...

Most ways of collecting images are based on the contact of light with materials. Film cameras catch images on light sensitive film that is developed into pictures using special processes. Digital ...

Integral to process control in many industries, level measurement sensors fall into two main types. Point level measurement sensors are used to mark a single discrete height (a preset level condition) ...
