- Description
- Microspectrophotometer specifications We are seeking a microspectrophotometer that we will use in a research project to identify pigments, fillers and binders in paint sampled from paintings and other works of art. The samples will be in the form of scrapings (transmitted light) and cross sections (reflected light) that will be examined using a microscope equipped with a spectrophotometer, By measuring the ultraviolet-visible-near infrared spectra (transmitted, reflected and fluorescence) of standards and unknowns we aim to create a database that can be used to identify materials in samples from works of art. We need the following specifications to do this: 1. A microspectrophotometer (ms) capable of measuring reflectance spectra from 200 nm to 850 nm. 2. An ms capable of measurement of transmitted light spectra from 200 nm to 850 nm. 3. Ability to acquire fluorescence spectra at five excitation wavelengths including the typical values of 254 nm, 365 nm, 405 nm, 436 nm, 546nm. The ability to change these is an advantage. 4. The entire accessible spectral range, 200-850 nm, should be able to be examined without changing optical components. 5. A high sensitivity detector is required, a Peltier or thermoelectrically cooled detector is required. 6. Transmission, reflectance and fluorescence spectra from areas as small as 4 x 4 microns should be obtainable. 7. The ability to locate the sample under examination using eyepieces is required since the fluorescence may be very weak and our samples are complicated. 8. True digital imaging is required with still and video image collection possible; the size at least 1.3 megapixels, 9. The ms should be controlled by software that has routines that can acquire and analyze spectral data. Software routines must be available for a) optimizing the system b) checking calibration, c) providing for optical alignment. For analyzing spectra, software should have cursor, zoom, autoscaling, peak marking/labeling. There should be output to printer or file of a) view through microscope, b) site of analysis and c) spectra from the site of analysis. 10. The computer provided for running the instrument should have 2.4GHz Pentium 4 processor or better, video card with minimum 32 Mbytes RAM, minimum 512 MB RAM, Windows 2000, compatibility with Gallery systems (ability to be networked), USB and firewire ports, high speed RW CD and DVD drive (40x), 18? flat panel monitor, minimum 80 GB 7200 rpm hard drive. 11. Very stable regulated power supplies for the lamps (should have > +/- 0.05% regulation and > +/- 0.05% current ripple) 12. Two days of onsite training and follow-up technical support via telephone. The NGA intends to contract for this annual requirement with the following firm, who has appears to meet all specifications needed. Craic Technologies2400 North Lincoln Avenue, Altadena, Ca.91001
