The flame spectrometer is designed for rapid determination of a wide range of concentrations (up to 8 orders of magnitude) of sodium, lithium, potassium, calcium, barium, caesium, rubidium in technological solutions. The excitation of atoms occurs in an air-acetylene flame. The device consists of a three-slit burner with flame control, a pneumatic sprayer, a spray chamber, an optical radiation input system into the "Hummingbird-2" spectrometer and an automatic air and acetylene supply system, with the possibility to control and adjust gas flow. The use of a three-slit burner provides increased flame temperature over the central slit of the burner due to the external flame layers. This makes it possible to determine low concentrations of calcium and barium. At the same time, it remains the possibility to determine impurities in highly concentrated solutions without clogging the burner slots. The lighting system of the spectrometer is mirror-lens, thanks to this, radiation collected from both sides of the burner is introduced into the polychromator.

The "10GBASE-SR SFP+ Module" optical modules are capable of operating at a data transfer rate of up to 10 Gbit/s and are used in fiber-optic communication systems. They have a form factor similar to the previous SFP standard, namely, they have much smaller dimensions compared to other 10G transceivers. They can be installed on network equipment with a large number of ports.
