What are the advantages of optical lens in medical and aerospace fields?
Optical lenses have many advantages in medical and aerospace fields, as follows:
Medical field:
Diagnostic aspects:
Improve imaging clarity: Optical lenses are widely used in medical equipment such as microscopes and endoscopes. For example, in a microscope, a high-quality lens can magnify tiny biological samples and reduce the scattering and distortion of light, so that doctors can observe the morphology and structure of cells and the details of diseased tissues more clearly, which is helpful for accurate diagnosis of diseases, such as observation of pathological sections and morphological analysis of cells. In endoscopy, the lens system can clearly transmit the images of the internal cavities and organs of the human body, which is convenient for doctors to make diagnosis, such as gastrointestinal endoscopy and bronchoscopy.
Enlarge the observation field of vision: Specially designed optical lenses, such as wide-angle lenses, can enlarge the doctor's observation field, so that the doctor can observe the lesion site and its surrounding tissues more comprehensively. For some parts that are difficult to observe directly, such as the bend of the intestine and the deep part of the sinus, it can provide better observation effect and improve the accuracy of diagnosis.
Treatment:
Precision laser therapy: In laser therapy surgery, the optical lens can accurately control the focusing degree and propagation direction of the laser beam. For example, in the laser myopia correction surgery of ophthalmology, the laser is accurately focused on the cornea through a specific lens, and the cornea is accurately cut, so as to change the curvature of the cornea and achieve the purpose of correcting myopia. In the laser treatment of dermatology, such as tattoo removal and spot treatment, the optical lens can ensure that the laser energy acts on the lesion accurately and reduce the damage to the surrounding normal tissues.
Auxiliary minimally invasive surgery: Minimally invasive surgery requires high accuracy and visualization of surgical instruments, and optical lenses play a key role in minimally invasive surgical instruments. For example, in laparoscopic surgery, through the optical lens system at the front end of the laparoscope, doctors can clearly observe the organs and tissue structures in the abdominal cavity in vitro, and use surgical instruments to perform accurate operations, thus reducing the size of the surgical incision and reducing the trauma and postoperative recovery time of patients.
Space field:
Space observation:
Enhance image resolution: Optical lens is one of the core components in observation equipment such as space telescope. High-quality optical lenses can gather more light, improve the resolution of the telescope, and enable scientists to observe the details of distant stars, galaxies and other celestial bodies more clearly. For example, the Hubble Space Telescope, which uses advanced optical lens system, enables human beings to observe the extremely distant and weak celestial signals in the universe, providing a lot of valuable information for astronomical research.
Adapt to harsh environment: The space environment is complex and harsh, with extreme temperature changes and radiation. Optical lenses need to have good stability and radiation resistance to ensure normal operation in space environment. For example, by using special materials and coating technology, the lens can maintain good optical performance in high radiation environment, and the optical performance will not be degraded due to the influence of radiation.
Spacecraft navigation and communication:
Accurate light control: in the navigation system of spacecraft, optical lens can be used to control the propagation direction and focusing degree of light. For example, in star sensors and other equipment, the light of stars is focused on the detector through optical lens, thus determining the attitude and position of spacecraft. In communication system, optical lens can be used to realize the coupling and transmission of optical signals, and improve the efficiency and stability of communication.
Reduce weight and volume: For spacecraft, the control of weight and volume is very important. By optimizing the design and using light materials, optical lenses can reduce their own weight and volume on the premise of ensuring optical performance, thus reducing the overall weight of spacecraft and reducing launch costs and energy consumption. For example, using new optical plastics materials or lightweight glass materials to manufacture optical lenses can effectively reduce the weight.
