The principle of operation of the device The principle of operation of the irradiator is based on the conversion of DC electrical energy into a normalized flow of ultraviolet radiation in the optical wavelength range of 350 ... 400 nm with a maximum at a wavelength of 365 nm. Design features and advantages The irradiator is a lantern consisting of an ultraviolet diode placed behind the focusing system, connected to a DC voltage converter, which supports the optimal mode of starting and functioning of the LED. Structurally, the irradiator is made in a lightweight duralumin housing, in the front of which there is a focusing system with an ultraviolet LED. The housing is equipped with a carrying strap. There is also a power on/off button on the case. As the power source of the irradiator, a lithium-ion battery of type 18650 with a nominal voltage of 3.7 V or 3 AA batteries with a voltage of 1.5V. are used. An ultraviolet LED is used as a source of ultraviolet (UV) radiation. The use of an LED distinguishes the UFO-3-20F irradiator from similar devices using UV lamps, it provides: high reliability and durability; variable diameter of the UV radiation zone; low current consumption and long continuous operation time; instant readiness for the first and subsequent turn-on; low weight, compact; high radiation intensity; stability of the characteristics of the irradiator, both during operation and throughout its entire life; wide operating temperature range. Scope of application The UV-3-20F irradiator (lantern) is used for ultraviolet irradiation of the surface of various parts, assemblies and mechanisms during flaw detection by fluorescent methods of non-destructive testing at machine-building enterprises, chemical and petrochemical industries, railway, automobile, water and aviation transport, during the laying and operation of pipelines, in construction, agriculture. The device can be used to check the quality of welds and internal surfaces of closed tanks. The luminescent method makes it possible to ensure high brightness and contrast of the indicator pattern, and, consequently, high sensitivity, especially on parts and products with a dark surface.

The lowest cost and most compact version of the LumoTrace® Optical Imaging System manufactured by Abisens LLC for sensitive bioluminescence detection. The compactness and low price of the LumoTrace®Lite imaging system are due to the fact that it allows only bioluminescence to be recorded (older models, in addition to bioluminescence, allow fluorescence to be recorded, and are also modular, which provides them with the opportunity to upgrade). Despite its compactness and relatively low price, this model is equipped with a new highly sensitive digital camera HICMOS manufactured by Abisens LLC, which allows recording ultra-small amounts of phosphor both in laboratory animals in vivo and in vitro experiments. The device is an indispensable tool for conducting preclinical studies on the way to the introduction of advanced drugs, in the implementation of non-invasive monitoring of the development of socially significant diseases, monitoring the effectiveness of immuno- and gene therapy,
