Sep 2008
Verity Instruments Inc.Request Info
CARROLLTON, Texas, Sept. 11, 2008 – Verity Instruments Inc. has released the SD1024FH super high performance spectrograph for semiconductor process control applications.

The spectrograph optimizes signal to noise performance via increased optical throughput, a data acquisition scheme, signal processing and system noise control. The 200 to 800 nm spectral range employs a 1024-element, scientific-grade thermoelectrically cooled CCD sensor designed specifically for challenging endpoint applications.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
An optical instrument for forming the spectrum of a light source and recording it on a film. The dispersing medium may be a prism or a diffraction grating. A concave grating requires no other means to form a sharp image of the slit on the film, but a plane grating or a prism requires auxiliary lenses or concave mirrors to act as image-forming means in addition to the dispersing element. Refracting prisms can be used only in parallel light, so a collimating lens is required before the prism and...
