The PARISS® Micro-Spectrophotometer Prisms Delivers Up to 90% Efficiency Over the Entire Operating Wavelength Range To Deliver More Sensitivity Than Most Diffraction Grating Based Spectrometers. • The prism spectrophotometer uses a prism with "curved" sides to make it optically “active.” The prism is actually closer to being a lens with a wedge.  An associated focusing mirror combines with the curved prism to deliver point- to-point imaging. • The reason the spectrophotometer prism has curved sides is to reduce, or eliminate, aberrations that can degrade spatial and spectral resolution. • All "points" on the entrance slit are imaged as points, at each wavelength, on the detector. Be sure to view the animation. • The prism spectrophotometer mounts as an accessory to most upright, inverted and stereo microscopes PARISS prism spectrophotometer schematic PARISS prism spectrophotmeter properties • Spectral range: 365 - 920 nm simultaneously • Spectral resolution ~1 nm at 436 nm • % Reflection • % Transmission • Absorption (Optical Density) • Color Coordinates (CIE) • Fluorescence, Luminescence • Build spectral libraries Copyright © LightForm Inc, 2011 View the presentation to learn more about the PARISS spectrophotometer
