Definitions

  • the invention relates to a microscope.
  • the technical problem on which the invention is based consists in specifying a microscope which is easy to transport and which can be subjected to rough handling and changing climatic conditions with dust and moisture loads when the place of use changes and which does not have the disadvantages described.
  • the microscope according to the invention is characterized in that the microscope has at least two chambers and that mechanical, optical and electronic components and assemblies are arranged in the different chambers. This makes it possible to design the chambers with different tightnesses.
  • the chamber with the mechanical components can have a low tightness with respect to moisture and a medium tightness with respect to dust, while a chamber with optical components has a high degree of tightness overall.
  • the at least two chambers are designed to be separated from one another by walls and / or seals. This has the The advantage that the chambers can have different levels of tightness.
  • the at least two chambers are sealed with different sealing devices to the outside and / or from one another.
  • the sealing measure necessary for the tightness required in each case can be provided.
  • the mechanical and optical and electronic components and assemblies are grouped together and arranged in one chamber each, which is designed to be adapted to the required tightness requirement in each case.
  • the chamber with the electronic components and assemblies requires a high degree of impermeability to moisture with low requirements regarding impermeability to dust.
  • the chamber with the mechanical components and assemblies preferably has the lowest degree of tightness and the chamber with the optical components and assemblies has the highest degree of tightness with respect to moisture and dust.
  • the mechanical components are accordingly preferably formed from a non-rusting material.
  • the electronic components are advantageously arranged in a chamber in a foot of the microscope, since in the An accumulator or a battery is also advantageously arranged on the foot and the paths for current-carrying lines are thus short.
  • the optical components are preferably arranged in a chamber in an upper part of the microscope, since the objectives, eyepieces and other optical elements are arranged above the object table. Incident light is also housed in this chamber.
  • a battery or accumulator compartment is provided in the housing.
  • the battery or accumulator compartment is closed with a lid.
  • the cover is advantageously fixed to the housing with safety screws. The safety screws can only be opened with special tools, so that unauthorized stealing of the batteries or accumulators is very difficult.
  • the invention consists in combining all electronic components into an assembly and, as shown in FIG. 1, placing them in an electronics chamber in the device base.
  • Mechanical parts including moving parts, are placed in the lower part of the housing in the mechanical chamber 2.
  • Optical components are housed in the upper part of the housing, the optics chamber 3. This creates a multi-chamber system.
  • the electronic components, the mechanical components and the optical components are each arranged in a separate chamber 1, 2, 3 and these chambers 1, 2, 3 are sealed from one another and from the outside.
  • the electronics chamber 1 contains an opening at the bottom, suitable for a cover 5 for changing the batteries or accumulators (not shown).
  • the seal is made with a flat seal 6, for example made of silicone.
  • a closed membrane 7, for example made of silicone, is located upwards towards the housing.
  • a stable wall 19 can also be used in place of the membrane.
  • the mechanical chamber 2 contains movable mechanical parts, some of which protrude outwards, such as cylinder pins 8 and a rotary axis 9 with a rotary knob 10 for adjusting the height of a worktop 11.
  • the cylinder pins are surrounded by guides with wipers 12, which prevent the ingress of foreign matter .
  • wipers 12 In the case of the axis of rotation, there is a requirement that it must be easy to move. Close-fitting seals, such as O-rings, for example made of rubber, could generate too much sliding friction, which would interfere with the operation of the height adjustment.
  • static friction causes a backward torque after turning the axis, whereby a microscopic object once brought into focus would slide out of the focal plane again after releasing the rotary knob.
  • a sliding bush 13 is used to support the axis of rotation, which is not designed as a high-density component.
  • the degree of protection of the mechanical chamber 2 is therefore relatively low, which is not a problem when using rustproof materials because of the lower sealing requirements of the mechanical system (see table above).
  • the optics chamber 3 is separated from the mechanics chamber 2 by a closed wall 19 at the bottom.
  • a glass window 17 In the direction of the objectives 16 there is a glass window 17 which is held in place with a sealing adhesive.
  • the objectives 16 themselves are manufactured in the standard version and do not contain any further protection. They are therefore to be regarded as wearing parts.
  • the degree of protection of the optics chamber 3 is at least IP64.
  • a condenser 4 is also to be regarded as an optics chamber and is correspondingly sealed.
  • a cover (not shown) screwed to the side of the housing 18 either contains a round cord running around the edge or accommodates an inserted flat seal.
  • the seal 7 and in the wall 19 there are holes for the passage of electrical lines.
  • the holes are sealed with a commercially available sealing cable gland or simply with an elastic adhesive. The elasticity of the adhesive allows pressure equalization between the chambers of the sealing system.
  • FIG. 2 shows the housing 18, which has an opening 22 that can be closed with a cover 20.
  • the lid 20 is fixed to the housing 18 with safety screws 21.
  • the safety screws 21 are designed in such a way that they can only be opened with special keys or screwdrivers, such as the screw 21 shown in FIG. 2a, which has an inner star 23.
  • a battery compartment 24 is arranged, in which batteries or accumulators 25 are arranged.
  • the batteries 25 must be replaced with new batteries after approximately 500 to 1000 charges.
  • a fuse 26 is also occasionally to be replaced by a replacement fuse 27. So that the batteries or accumulators 25 cannot be stolen by unauthorized persons, the cover 20 is designed to be lockable, specifically with the aid of the safety screws 21.
  • the use of the safety screws 21 has the advantage that dust and moisture are prevented from entering the microscope .
