          Optical platform manufacturer 's optical platform comprehensive introduction

          The optical platform, also known as optical breadboard, optical desktop, scientific desktop, experimental platform, for the level, stable table, the general platform need to be isolated and other measures to ensure that it is not subject to external factors, so that scientific experiments are normal. Optical platform to pursue the level of the first processing when the entire table is extremely flat. After the table placed with four Unicom on the airbag to ensure the level of the table. The table is covered with a square thread of engineering holes, with these holes and the corresponding screws can be fixed optical components. In this way, when you complete the construction of optical equipment, the system will not be subject to external disturbance and change. Even if you press the table, it will automatically return to the level because of the airbag.

          Types of

          The optical platform is functionally fixed and adjustable; passive or active.

          application

          Optical platform is widely used in optical, electronics, precision machinery manufacturing, metallurgy, aerospace, aviation, navigation, precision chemical and non-destructive testing and other fields, as well as other machinery industry precision test equipment, equipment, vibration isolation of the key device.

          The main components of the standard optical platform include: 1, the roof; 2, the bottom plate; 3, side finishing face; 4, side panels; 5, honeycomb core; 6, sealed cup.

          Steel structure

          High-quality platforms and breadboards should have a steel structure, including 5 mm thick roof and floor, and 0.25 mm thick machined welded steel honeycomb core. The honeycomb core is made with an accurate lamination tool to ensure its geometric spacing by welding the flat washer. The honeycomb core structure in the platform and breadboard extends from the top plate to the bottom plate with no transition layer in the middle, resulting in a stronger, more thermally stable platform product.

          Thermal stability

          The key to thermal stability lies in the axial direction of the symmetrical, uniform steel structure. The extensibility and shrinkage of steel components during heat exchange are similar and can maintain good flatness during temperature changes. The steel honeycomb core structure extends from the top plate to the bottom plate, with no plastic or aluminum leakage management structure in the middle, so that the overall rigidity of the platform is not reduced or a higher coefficient of thermal expansion is introduced. We use steel side panels, not wood, which eliminates the environmental instability caused by humidity.

          Precision Machining

          Automated processing

          Automated processing system platform and breadboard special is the use of automatic track mechanical matte surface processing, than the old platform products more smooth and smooth. With improved surface finish of these platforms, the surface flatness is ± 0.1 mm (± 0.004 in.) In 1 square meter (11 square feet), providing a contact surface for the mounting parts without the need for abrasive To polish.

          Large radius angle

          Platform and breadboard design can also use large radius fillet, which can reduce the sharp edges in the laboratory, improve safety.

          Main accessories

          Support frame

          The optical platform includes rigid, non-vibration-proof support frame, passive vibration-proof support frame, active automatic leveling support frame.

          Other Accessories

          Optical platform Other accessories include shelves, mounts, table shelves, vibration isolation accessories, optical platform accessories with adjustable struts, adjustable optical climbing mounts, earthquake suppression, optical breadboard hoods, shading materials, magnetic Flakes and so on.

          Production significance

          Scientific experiments in today's scientific community require more sophisticated calculations and measurements, so a device that is relatively isolated from the external environment and interference is important for measuring the results of the experiment. The optical platform capable of fixing various optical elements and microscope imaging devices has also become an essential product in scientific research experiments. One of the main goals of the optical platform is to eliminate the relative displacement between any two or more components on the platform.

          Test Methods

          Damping

          The most important characteristic of an optical platform or breadboard is its resonant frequency. The resonant frequency and amplitude are negatively correlated, so the resonant frequency should be increased as much as possible to minimize vibration intensity. The platform and breadboard will vibrate within a specific frequency range. In order to improve performance, the damping effect of each size platform and breadboard needs to be optimized.

          Platform damping requires a variety of tests to optimize the thickness / area ratio. A larger area of the platform (at least 10 feet or 3 meters long) has a standard thickness of 12.2 in. (310 mm), which improves stability. For smaller areas of the platform, the thickness can be 8.3 inches (210 mm) or 12.2 inches (310 mm), can also be customized larger size.

          Compliance

          The most widely used vibration response transfer function for optical platforms is compliance. In the case of constant (static) force, the compliance can be defined as the ratio of linear or angular misalignment to the applied external force. In the case of dynamic change forces (vibrations), the compliance can be defined as the ratio of the amplitude of the stimulus (angle or linear misalignment) to the amplitude of the vibrational force. Any deflection of the platform can be manifested by the relative position change of the components mounted on the surface of the platform. Thus, by definition, the smaller the compliance value, the closer the optical platform is to the primary goal of the design: to minimize deflection. Compliance is frequency dependent, and its unit of measure is the amount of misalignment (m / Newton) without unit force.

          Measurement methods

          Apply a measured external force to the surface of the platform or breadmaker using a pulse hammer and apply a sensor to the surface of the platform or breadboard to measure the synthetic vibration.

          The signal from the detector is read by the analyzer and used to generate the frequency response spectrum (ie, the compliance curve). During the development of the optical platform, the compliance curves at many points on the surface of the platform are recorded; however, the compliance at the four corners of the platform is often the largest. So the company issued the compliance curve and data are measured through the flat sensor in the four corners of the measured, so that the most unfathomable data results.

          Single test data

          The product is subject to independent testing and is accompanied by a separate test data report and compliance curve. In this way, more data can be provided than industry standards that use a single size compliance curve to represent all product characteristics. The compliance curves and data are measured by the flat sensor at four corners of the table, thus indicating the most unfounded data results.
