The attached file contains the transmission spectrum for the Vernier Emissions Fiber (VSP-EM-FIBER). The transmission spectrum is fairly flat across all wavelengths measured by the Vernier Emissions Spectrometer (VSP-EM) and is comparable to the transmission spectrum for the Vernier UV-VIS Spectrometer Optical Fiber (VSP-UV-FIBER, discontinued).
