  • Microspectrophotometer

Jul 2010
CRAIC TechnologiesRequest Info
The 20/20 FPD microspectrophotometer from Craic Technologies Inc. is designed for colorimetry and light intensity comparison of microdisplays of all types. Able to nondestructively measure spectra on the micron scale, it can map the color and intensity variations within a single pixel, providing the manufacturer with the ability to optimize and improve the microdisplay manufacturing process. The device enables colorimetry, spectroscopy and imaging of small-scale pixels that are common with high-resolution microdisplays, and it also can be configured to measure thin-film thickness and source intensity. It can image in the UV, visible and near-IR regions.

The attribute of visual experience that can be described as having quantitatively specifiable dimensions of hue, saturation, and brightness or lightness. The visual experience, not including aspects of extent (e.g., size, shape, texture, etc.) and duration (e.g., movement, flicker, etc.).
The methods used to measure color and to define the results of the measurements.
Flux per unit solid angle.
A transmissive, reflective or emissive high-resolution display that typically measures 1 cm diagonally, and whose use requires magnifying optics to project a highly magnified image on a surface for the image to be observed by the viewer.
A specialized spectrophotometer for use through a microscope on very small areas of an object.
Contraction of "picture element." A small element of a scene, often the smallest resolvable area, in which an average brightness value is determined and used to represent that portion of the scene. Pixels are arranged in a rectangular array to form a complete image.
1. In optics, the ability of a lens system to reproduce the points, lines and surfaces in an object as separate entities in the image. 2. The minimum adjustment increment effectively achievable by a positioning mechanism. 3. In image processing, the accuracy with which brightness, spatial parameters and frame rate are divided into discrete levels.
thin film
A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
