In what fields do we usually use optical glass lenses?


Optical glass lenses are widely used, mainly including the following aspects:

Optical instrument field:

Microscope: The microscope consists of an objective lens and an eyepiece with a set of lenses at each end. The objective lens is close to the observed object, making the image of the object within the focus of the eyepiece, and then magnifying it into a virtual image by the eyepiece. The high precision and high light transmittance of optical glass lens can ensure that the images observed by microscope are clear and accurate, which is very important for the observation and research of tiny objects such as cells, microorganisms and tissue slices.

Telescope: Optical glass lens is the core component of both astronomical telescope and ordinary binoculars. For astronomical observation, high-quality lenses are needed to collect and focus the faint light emitted by distant celestial bodies so that observers can see clear images of celestial bodies; In daily life, people use binoculars for outdoor observation, bird watching, performances and other activities, and the performance of optical glass lens directly affects the observation effect.

Projector: The projector works by using the principle that the convex lens can enlarge and invert the real image. The optical glass lens can focus and adjust the light emitted by the light source, so that the projected image is clear and uniform in brightness. Projectors are widely used in education, business meetings, home theaters and other scenes.

Camera lens: whether it is a traditional film camera or a modern digital camera, optical glass lens is the key factor to determine the imaging quality. Different types of camera lenses, such as wide-angle lens, telephoto lens and macro lens, all need to use high-quality optical glass lenses to achieve different shooting effects.

Medical field:

Ophthalmic instruments: Optical glass lenses are used to focus light and enlarge images in ophthalmological examination and diagnosis equipment, such as optometry, slit lamp and ophthalmoscope, so as to help doctors accurately observe the eye structure and pathological changes of patients. For example, the lens in the optometry instrument can focus the light on the patient's retina, and determine the patient's vision problem by measuring the refraction of the light.

Medical laser equipment: In the laser treatment equipment, the optical glass lens is used to focus the laser beam so that it can accurately act on the diseased tissues, such as laser freckle removal and laser myopia correction surgery. High-quality lens can ensure the energy concentration and stability of laser beam, and improve the therapeutic effect and safety.

Security monitoring field: In the monitoring camera, optical glass lens can improve the clarity and resolution of the image, making the monitoring picture clearer and richer in details. Especially in some places with high monitoring requirements, such as banks, airports, shopping malls, etc., high-quality optical glass lenses are needed to ensure the monitoring effect.

Optical communication field: In optical fiber communication system, optical glass lens is used to couple optical fiber with light source, detector and other devices, and effectively transmit and receive optical signals. For example, in the optical module, the lens can focus the light emitted by the laser into the optical fiber to realize high-speed and stable optical communication.

Aerospace field: In aerospace equipment such as airplanes and satellites, optical glass lenses are used in navigation systems, observation equipment and remote sensing instruments. For example, optical remote sensing instruments on satellites need to use high-quality lenses to collect information on the earth's surface and provide data support for weather forecasting, resource exploration and environmental monitoring.

Scientific research field: In the scientific research of physics, chemistry and biology, optical glass lenses are widely used in various experimental equipment and instruments. For example, in physical experiments, lenses can be used to focus laser light and generate parallel beams. In chemical experiments, lenses can be used to observe microscopic phenomena in chemical reactions; In biological experiments, lenses can be used to observe cell structure, microbial activities and so on.

Lighting field: In some special lighting equipment, such as car headlights, stage lighting, etc., optical glass lenses can be used to control the propagation direction and intensity of light and achieve specific lighting effects. For example, the lens in the car headlights can focus the light emitted by the light bulb into parallel beams, thus improving the brightness and range of illumination.
