About this file

Written by GovTribe AI ·

This document contains specifications for a handheld near infrared spectrometer and details of a related federal contract opportunity. The specifications outline key parameters for the spectrometer including illumination sources using two integrated vacuum tungsten lamps with a bulb life of over 40,000 hours. The spectrometer is to have a sample working distance of 0-15mm from the window with an optimal distance of 3mm. It should contain a 128 pixel InGaAs photodiode array with a pixel size and pitch of 30um x 250um/50um. The wavelength range is specified as 950-1650nm or 10,526-6060cm-1 with a pixel-to-pixel interval of 6.2nm over that range. The spectral bandwidth is also specified. The related federal contract opportunity is a solicitation from the Department of Agriculture Agricultural Research Service seeking quotes for a handheld NIR spectrometer or equal product to the brand specified in the specifications. The solicitation number is 12905B23Q0237 and is open to vendors in Albany, California.
