• Aspherical Lenses

  by benao ptics Fri at 2:18 AM
  Aspherical lenses do not have a simple spherical surface; instead, they have a rotationally symmetric, smooth, and continuous aspheric surface that conforms to a specific expression. This design allows light to travel through the lens in a more ideal path, thereby reducing aberrations and improving ...

• Anti-Reflection Coating (AR)

  by benao ptics Fri at 2:17 AM
  The anti-reflective coatings (also known as AR coatings) is to reduce or eliminate the reflection of light on optical surfaces such as lenses, prisms, and mirrors. This increases the amount of light transmitted through these elements and reduces or eliminates stray light in the system. AR coatings a...
