These spectrometers work across a broad spectral range (UV-VIS – NIR – SWIR) and are designed to maximize the probe light throughput in HELIOS and EOS spectrometers. They consist of an imaging spectrograph and a high-speed multichannel detector. The spectrograph utilizes a high-efficiency, ion-etched, aberration-corrected holographic grating. After an optical fiber, light travels directly to the grating. The grating simultaneously disperses and refocuses light onto the sensor without the use of any additional mirrors, lenses, etc. The height of the projected spectral image remains virtually the same as the diameter of the input optical fiber, ensuring minimal losses at the sensor. The multichannel detectors have 0.5 mm tall pixels, which are optimal for spectrometry.
