This spectrometer is designed for low light applications that require high spectral acquisition rates. The spectrometer consists of an imaging spectrograph and a high speed multichannel detector. The spectrograph utilizes a high-efficiency, ion-etched, aberration corrected holographic grating. The spectrograph design is optimized for maximum light throughput. 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. This way the light spectrum can be focused on the sensor with minimal losses.
