Spherical lens features

As the name suggests, the short-wave pass filter is a cut-off filter that allows the light in the short-wave direction to pass through and the long-wave direction. It is completely different from the traditional optical glass method. When the incident angle changes (from 0 degrees to a large angle), the cut-off wavelength will move to the short-wave direction. This function can be used in system fine-tuning and can Get the wavelength you need.

Application

Application range: Glass lenses have a wide distribution of refractive index and dispersion, and have good adaptability to temperature and environment. They are widely used in high-end optical lenses, such as digital cameras, security, automotive, optical communications, laser projection, medical, unmanned machine, AR, etc.
