To achieve the maximum sensitivity during measurements, a special prefix is used to the FT-801 Fourier spectrometer, which is an optical unit with a built-in highly sensitive MST detector cooled with liquid nitrogen. The set-top box is installed in the cuvette compartment of the spectrometer and connected to the corresponding external electrical port, the detector is turned on programmatically. In this case, the sensitivity of the method increases many times (up to 20) – depending on the type of standard uncooled detector in the spectrometer). The speed of recording spectra is also increasing. The operating time after filling the cryostat (200 ml capacity) with liquid nitrogen is at least 6 hours. Increasing the sensitivity of the spectrometer using a prefix with an MST detector may be required for many applications: in fiber spectroscopy, when recording emission spectra of low-power emitters, in trace gas analysis with high spectral resolution, when determining the presence of impurities in samples in ultra-low concentrations, when using multi-pass gas cuvettes, etc. In the picture: on the left in the cuvette compartment there is a capler with fiber from Art photonics GmbH, Berlin, Germany, on the right there is a prefix with an MST detector. Technical specifications The recommended number of scans when registering spectra is 16 Spectrum registration time at 50 scans (resolution 4 cm-1), sec 20 Cryostat capacity, 200 ml Working time after filling the cryostat, 6 hours Overall dimensions, mm 225×175×75 Weight, kg 1.45

The 3KN-2,5 intake valve includes a nut, the filter is installed in the housing between the two rings. The opening of the inlet valve 3KN-2,5 is carried out when the electromagnet coil is de-energized and the armature returns to its original position under the mechanical pressure of the spring. The closure of the 3KN-2,5 intake valve occurs when an electric voltage of a certain power is applied to the terminals of the coil. The anchor is involved in the shoe, ensuring the closure of the ductal canal.

The speed of the pneumatic cylinder in particular and the operation of the shutter as a whole are regulated by rotating the pneumatic throttle head, if the pneumatic throttle heads are fully tightened, then the speed of opening and closing the shutter will be maximum. The solenoid, powered by a connector, serves as a distributor control device and is applicable in standard production conditions where the relative humidity of the air is not higher than 75%.

It is the holder with spring clip for working viscometers of types VPJ 1, VPJ 2, VPJ 4, residence permit, Cannon Fenske Routine, Cannon FenskeOpaque, Ubbelohde, BS/IP/RF.

It is designed for measurement by the method of disturbed total internal reflection with simultaneous visualization of a micro-object on an integrated and external monitor, as well as by the method of mirror-diffuse reflection with an angle of incidence of 45o at the upper location of the sample. The prefix in the mode of a single NIP is used to register absorption spectra: liquids of any degree of viscosity (solutions, suspensions, oils, etc.), including those with high chemical activity; solid objects of arbitrary shape, including samples with very high hardness (any polymers, fragments of paint coatings, etc.); powdery substances, including powders with very high hardness (drugs, pharmaceuticals, explosives, inorganic compounds); samples in the form of thin tapes; samples in the form of fibers. The maximum hardness and chemical resistance of the diamond significantly expand the possibilities of the method; there is no need for periodic replacement of the crystal. The set-top box allows you to register spectra without time–consuming sample preparation, and the presence of a visual inspection system of the studied surface with a high-quality video camera and a built-in high-definition mini-monitor increases efficiency when working with small samples - fragments of thin fibers, microparticles, etc. The built-in monitor has the functions of digital 10X zoom, inverting, etc. The image can be simultaneously displayed on the computer screen (using a USB interface) and then saved as a file. The removable flange provides a quick and convenient sample change and cleaning of the crystal surface. The design with a diamond element protruding above the base plane of the NPVO allows you to study samples with sufficiently large overall dimensions. The high quality and repeatability of the results is achieved due to the absence of the influence of the thickness of the substance layer on the shape of the spectrum and the intensity of the absorption bands. The sample retains its original physicochemical properties and, if necessary, can be further investigated by other methods. The universal attachment clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements. For convenience when working with liquid and paste-like samples, as well as in the ZDO mode, it is possible to rotate the clamping console by 180o. The console is equipped with two replaceable tips – with a spherical working part and with a flat hinged head. The high hardness of the diamond allows the use of large clamping forces, which is the determining factor for obtaining high-quality spectra. A replacement table is used to register the specular and diffuse reflection spectra. The sample is located on the subject plane of the investigated surface downwards. The method is used to determine the spectral characteristics of optical parts, thin tapes on the surface, crystals, and other large solid objects of arbitrary shape and size.
