# 508 Coal Microscope Spectrometer > The 508PV™ microscope spectrophotometer is designed to add spectroscopy, color imaging, and vitrinite reflectance capabilities to your optical microscope. Source: https://www.microspectra.com/product-service/365-508-coal-microscope-spectrometer/ ## Vitrinite Reflectance Measurements with Spectroscopy & Imaging The 508PV™ microscope spectrophotometer is designed to add spectroscopy, color imaging, and vitrinite reflectance capabilities to your optical microscope. It can also be used to upgrade an older microspectrometer with cutting edge optics, electronics and software. The 508PV™ attaches to an open photoport and enables you to collect transmission, reflectance, polarization or even fluorescence and luminescence spectra of microscopic samples. Featuring LightBlades™ spectrophotometer technology from CRAIC, the 508PV™ spectrophotometer has a usable spectral range from the ultraviolet to the near infrared. With the 508PV™, you can acquire high quality spectra of even sub-micron samples rapidly, non-destructively and with ease. The 508PV™ microscope spectrophotometer is ideal for diverse applications such as colorimetry of pixels on flat panel displays, reflectometry of vitrinite coal and source rock, or thin film thickness measurements of optics and semiconductors. The 508PV™ is also a cost effective way to upgrade older microspectrometers to the latest hardware and software. ## Features ![508 PV on Microscope](https://www.microspectra.com/wp-content/uploads/2026/08/508_transparentscopeR.png) ### Key Features* Add the 508PV™ to any microscope or probe station for spectroscopy, colorimetry and micro spot film thickness. - Featuring [LightBlades](https://www.microspectra.com/product-service/236-lightblades/)™ spectrophotometers designed specifically for microspectroscopy - User selected spectral range from deep UV to NIR - 250 to 2100 nm available spectral range - Permanently calibrated, variable measurement areas even below a micron - Thermoelectric cooling available to improve signal-to-noise ratios and long term stability. - Incorporates high resolution, color digital imaging…up to 6 megapixels available - Featured with [Lambdafire™](https://www.microspectra.com/products/craic-software/lambdafire-spectroscopy-software/) spectroscopy and imaging control and analysis software.
