Laser Collimation and Focusing Systems: Fundamental to applications such as laser processing, holographic projection, and interferometry.
Galilean Beam Expander: Combined with plano-concave lenses.
Imaging and Optical Systems
Imaging, Beam Expanding, or Beam Shrinking: Used for relaying images and changing the cross-sectional size of the beam (magnification or reduction), widely used in various precision optical instruments.
Projection and Illumination Systems
Collecting light from a light source and focusing or uniformly projecting it onto a target area, improving light energy utilization efficiency and illumination uniformity.
Classic Historical Applications
Galilean Telescope: As an objective lens, it focuses light from distant objects to form an intermediate image. A core component of the first refracting telescope used for astronomical observation.
Specialty Materials Applications
Infrared Optics and Excimer Lasers: Utilizing the ultra-wide transmittance and high laser damage threshold of calcium fluoride (CaF₂) from ultraviolet to infrared (180-8000nm), it is used in high-power laser systems and infrared imaging. Suitable for cutting-edge applications with special requirements for wavelength and power.
