Did you know that fused‑silica transmission gratings can be used for UV-VIS spectroscopy? In many applications, only the UV-region is of interest and typically instruments are designed with reflective blazed or holographic gratings. However, our transmission gratings - etched directly into fused silica - can often outperform all other types of gratings. This plot shows how our 2421 lpmm fused‑silica transmission grating delivers higher diffraction efficiency across the entire UV-region compared to commonly used reflective blazed and holographic gratings. This performance is achieved through a precisely engineered tooth profile and the near‑100% transmission of the thin fused‑silica substrate. Find out about the advantages

Why does throughput matter in the design and performance of spectrometers? Understanding throughput is key to improving how effectively a spectrometer collects and transmits light, which directly affects its sensitivity and accuracy. In this white paper, we break down fundamental concepts like étendue and explain how the efficiency of optical components such as gratings, lenses, mirrors, and detectors plays a vital role in the overall system’s performance. If you want to gain deeper insight and enhance your designs, this white paper is for you. It covers the definition and importance of throughput, shows how each component influences it, and offers
