Developments
- Non-contact spectral ratio pyrometer DPR-1.
It is used for contactless temperature measurement, temperature pattern visualization and storage. DPR-1 is fast, highly precise and operationally flexible. It performs a radiance measurement in two spectral zones of a heated object, then evaluates the object temperature from the radiance ratio adjusted to the temperature of the external environment. Computation and data handling is performed by the microprocessor.
- Pyroelectric devices for laser technology.
I. Pyroelectric power meter VP1.
Pyroelectric power meter VP1 measures the mean power in the range from 2mW to 2000 mW of a coherent and noncoherent electromagnetic radiation (wavelength range is 0.25µm – 14µm).
II. Pyroelectric transmission-type receiver.
Pyroelectric transmission-type receiver is a portable system designed to operate as detector and laser window.
- Laser complex for distance measurement.
The complex employs an original method of distance measurement using the frequency modulated radiation of fiber laser with frequency-shifted feedback. It is compact, consistent in operation and noise-resistant.
- Frequency-stabilized He-Ne laser.
Laser frequency is stabilized by the resonant saturated absorbtion of molecular iodine. High frequency laser pumping is used to decrease fourfould the amplitude noise level comparing with conventional DC feed circuits. Relative frequency instability is decreased to 5x10-13 (averaging time 100s).
- Ultrafine polarizers made of liotropic chromonic liquid crystals.
They are fabricated of ultrafine (thickness is less that 1 µm) dye films deposited on the liotropic chromonic liquid crystal substrates. Polarizer transmittance is balanced in a wavelength range of 450 – 800 nm.
- Sensory spectrometric analyzer of water quality AQUA-TEST SP.
It is designed to obtain the water quality information using the fotometric method in field environment. Used with the portable laboratory AQUA-TEST 2000, it can measure mass concentrations of 30 substances with accuracy 1–5%.
- A device for distant on-the-fly measuring of box temperature in the railway rolling stock.
It is designed as a part of automated remote control system (ARCS) for railway rolling stock. It employs twospectral infrared radiometer, which has a vibration-resistant sensor system.
The device is placed in a floor camera fastened to the rail. It includes optomechanical detector and microprocessor automated control system, which are managed by a ARCS computer.
- A novel plasma technique to coat anilox rolls.
Anilox rolls are the key elements of the aniline ink distribution system used in the printing process for processing of paper and textile materials.
Based on the recent developments in plasma science, a novel plasma-based functional coating laboratory facility for the ion-plasma-treatment of anilox rolls includes equipment for pre-heating, ion cleaning and magnetron sputtering. It is particularly suitable for the high quality depositing of metallic and ceramic coating onto the cylindrical outer surface of anilox rolls.
- Electric power-saving device.
It is used to operate lighting systems consisting of fluorescent lamps and other light sources. The device registers infrared heat radiation to determine whether a human is near. Once a human enters a lighting area, the lights are turned on. And vice versa, it turns off the lighting system if there are no human in the lighting area. The device can also be programmed to respond to the changes in the level of ambient illumination.
- Passive laser shutters (PLS).
PLS are designed to control the Q-factor and synchronize modes of solid-state lasers, as well as to provide optical insulation between laser amplifier stages. PLS can regulate pulse duration and pulse power without using electrical signals. PLS are constructed by sandwiching a dyed polymer matrix between the two substrates, which allows the fabrication of PLS of different sizes.
- Iodine absorbing cells for laser metrology and spectroscopy.
They are important elements of high-stable laser systems engaged in the research experiments in metrology and spectroscopy. The fabricating and quality controlling processes of iodine absorbing cells meet all the requirements of International Committee for Weights and Measures.
- Universal Temperature Regulation Cryogenic System “UTRECS” for microoptical measurements.
They are used together with optical microscopes for microoptical measurements in a range of temperature between 5 K and 1000 K.
- Laser-water jet cutting head.
It is developed for making holes and cutting of silicon wayfers and other materials.
The cutting process is performed in water. Apart from the low pressure water, high pressure water microjet is supplied to the cutting point, providing effective cooling and removal of ablation products. The laser beam passes through the low pressure water cell and is focused on the workpiece in the center of high pressure water microjet (up to 200 Bar).
- Laser-induced plasma complex for micromachining of transparent materials.
It is designed for precise micromachining, for example microlabeling, of transparent materials. Cheap and reliable neodymium laser of wavelength 1.06 µm or 0.53 µm induces intermediate plasma phase which imparts energy into material.
- Photoacoustical microscope.
Photoacoustical microscope is designed for nondestructive quality control of microwelded interconnections in silicon chips.
- Laser complex for micromachining of opaque materials "MICROSTAMP".
It is designed for micromachining of metal, ceramics and superhard materials. The technological process includes depositing of the polymer mask on a sample. Then laser radiation evaporates the mask.
- Laser complex for machining of nonmetallic materials.
It used for cutting and etching of plastic, glass, and wooden plates of thickness up to 10 mm. The complex is compact and cost-efficient.
- DC glow-discharge plasma sterilizer for medical equipment.
The sterilizer generates dense and highly uniform plasma which is particularly suitable for fast and efficient sterilization of medical instruments, especially those with canals and deep holes. Sterilization process includes the two repetitive treatment stages. During the “steam” stage chemical steam is injected into the vacuum-processed camera with medical instruments. Highly efficient penetration of steam into packets and hard-to-reach places is performed by a dedicated injection/evaporation system. After the “steam” stage the camera is vacuumized again, which is followed by glow-discharge plasma treatment stage.
- Holographic optical elements.
A new highly efficient technology for volume holographic grating recording in a wavelength range 350-670 nm allows to fabricate optical elements, which are used as polarization elements, interference filters, controlled beam splitters, dispersion laser elements, and diffraction elements for spectral devices.
