Abstract
The utility model provides a single beam ultraviolet-visible spectrophotometer, which comprises a base frame (1), an external cover cap (2), a monochromator (3) with a cover arranged on the base frame (1), a radiator (6), a light house assembly (5), a power transformer (10), a receiver (16) and an optical filter box (18). The single beam ultraviolet-visible pectrophotometer is characterized in that the optical filter box (18) is arranged inside the cover of the monochromator (2). As the filter disk of the traditional spectrophotometer arranged at the light inlet position of the light house is moved into the cover of the monochromator, not only the defects that the optical filters of the similar traditional spectrophotometers are easy to be polluted, deliquated and funked are effectively eliminated, but also the parasitic light is treated more effectively in the interference detection results because of the improvement in the designed position. In this way, the single beam ultraviolet-visible spectrophotometer can improve the test effect of monochromatic light.
Description
Technical field
The utility model relates to a kind of spectrophotometer, especially a kind of single beam ultraviolet-visible spectrophotometer; Belong to the optical instrument class.
Background technology
In traditional photometer design, usually filter disc is contained in the lamp house that advances optical position of lamp house, and the area of the optical filter that is adopted is also bigger.The photometer of this traditional design very easily is subjected to the pollution of environment because optical filter is directly exposed design in the lamp house of instrument, especially in the temperature environment of lamp house and the influence of humid air, is subjected to deliquescence and causes optical filter to go mouldy.Finally not only influence photometric detection effect, and will shorten the serviceable life of instrument.
Therefore, the structural defect that how existing single speed ultraviolet-visible photometer is existed carries out necessary improvement and innovation, has both made optical filter avoid the pollution and the damage of environment, also can press the serviceable life of long whole instrument simultaneously.
The utility model content
The purpose of the present utility model: be intended to propose a kind of novel single beam ultraviolet-visible spectrophotometer, both made optical filter avoid the pollution and the damage of environment, also can press the serviceable life of long whole instrument simultaneously.
This single beam ultraviolet-visible spectrophotometer; Comprise base 1, outside housing cover 2 and be arranged on band cover monochromator 3, heating radiator 6, lamp room component 5, power transformer 10, receiver 16 and optical filter box 19 on the base 1, it is characterized in that: described optical filter box 19 is located in the cover body 21 of monochromator 3.
Described optical filter box 19 is made up of the five tablet filter 19-1～19-5 and the anti-dazzling screen 19-6 that are located on the filter disc dish 19-7 at least, and forms the rotatable filter assembly by the CD-ROM drive motor 19-9 that is connected with filter disc dish 19-7.
The specification of described each optical filter is 26mm * 5mm * 2.5mm.
This single beam ultraviolet-visible spectrophotometer according to above technical scheme formation; Because traditional spectrophotometer is located at the filter disc that lamp house advances on the optical position to move in the monochromator cover body, really because the improvement on this design attitude, optical filter vulnerable to pollution, deliquescence and the mouldy drawback of not only effectively having avoided traditional spectrophotometer of the same type to exist, and more effective to the processing of the veiling glare of interference detection results, play and improve the ideal role that monochromatic light detects effect.
