Craic Technologies has introduced the 308 FPD spectrophotometer, which is designed to allow high-spatial resolution mapping of colour and intensity of micro displays.
The instrument is easily attached to inspection microscopes and probe stations and is used to measure colour and relative intensity on the micron scale.
Micro displays are currently being developed for the next generation of displays and feature ever smaller components.
They are being developed for applications including helmet-mounted devices and high-resolution media glasses.
Component geometries have shrunk so much that standard metrology tools have difficulty accurately measuring colour and intensity variations with the degree of spatial resolution required.
Craic's 308 FPD microscope spectrophotometer is designed to measure and compare the spectral output, intensity and colour consistency of each microscopic pixel of the micro display.
With demand for ever-higher resolution combined with smaller cross-sections, the dimensions for components such as pixels are rapidly shrinking.
It is challenging with current technologies (less than 10 microns across for pixels) to map colour and intensity variations of groups of pixels, much less of a single pixel.
The 308 FPD spectrophotometer is designed to add to the open photoport of a microscope or probe station and allows the user to acquire images and spectra of microscopic sample areas quickly and rapidly.
When added to the appropriate microscope or probe station, the 308 FPD can be used to measure the colour and intensity of each pixel of a micro display.
Pixels can then be compared to one another for consistency or maps of both the intensity and colour can be generated for each device.
The 308 FPD instrument can acquire spectra on the order of a few milliseconds, entire micro displays can be mapped quickly and accurately.
This ensures both the colour and intensity will be consistent across the entire device as well as from device to device.
