MicroLAB - Model 141 - Visual Spectrophotometer for Emission and Absorption Spectra Analysis

The Model 141 Visual Spectrometer by MicroLAB Inc. is a pivotal component within a modular spectrometer system, designed for the precise analysis of visible region emission and absorption spectra. This instrument integrates a sample holder and an adjustable slit assembly, offering three laser-cut slit widths—760, 380, and 125 microns—that influence the spectral resolution and light throughput. With a full width half maximum resolution of 6 nm at its narrowest slit, this spectrometer ensures consistent accuracy across the spectrum. Components like a collimating lens and diffraction grating strategically placed from the slit facilitate the creation of detailed spectra. It supports various methods for viewing or recording the spectra, including direct observation, video camera usage, or cell-phone camera integration. The Model 141 enables extensive experimentation, such as examination of line and band spectra, wavelength calibration, and determination of spectral profiles, supporting a broad scope of spectrophotometry applications.
