The optical resolution and sensitivity are two important parameters when performing spectroscopic measurements that can be improved by changing an optical element at the entrance of the spectrometer. This optical element, which is called slit, acts as the entrance aperture and regulates the width of the light beam entering the spectrometer optical bench.

Currently, every series of Sarspec’s spectrometers offer every user the possibility of adding filters at the entrance of the spectrometer, after the slit.

The spectrometers manufactured by Sarspec are high-quality systems with an aluminum alloy optical bench that has been thoroughly optimized for each optical element.

The diffraction grating is the main element in the optical system of a spectrometer that separates incident polychromatic radiation (white light) into monochromatic radiation (light of one color). It consists of a series of parallel grooves, equally spaced and formed in a reflective coating deposited onto a glass substrate.

The collecting lens is a cylindrical lens fixed in front of the detector for focusing the entire height of the monochromatic light onto the shorter detector pixels.
