CAY033 In Stock

The CAY033 by ThorLabs is a cutting-edge plastic aspheric lens that utilizes advanced molding technology to deliver high-performance all-plastic optics. Designed by Philips for high-volume applications at an affordable price, the CAY033 is the ideal choice for low-power applications that require lightweight and reliable optical components.

One of the standout features of the CAY033 is its innovative design that eliminates spherical aberration on the lens surface. This allows for the spot size and collimation of a monochromatic beam of light to approach the diffraction limit, ensuring superior optical performance. In laser diode systems, correcting for aberration can be challenging due to the high divergence angle of the beam. Traditional spherical lenses introduce spherical aberration when refracting light at large angles, necessitating the use of multiple elements for collimation. However, the CAY033 overcomes this limitation by collimating without introducing spherical aberration, making it a highly efficient and reliable choice for laser diode systems.

When coupling the CAY033 into fiber, achieving a near-diffraction-limited spot size is often essential. Traditional spherical elements are often limited by spherical aberration, which prevents achieving a small spot size at the diffraction limit. However, the CAY033's diffraction-limiting design minimizes spherical aberration, allowing the focal spot size to approach the diffraction limit for precise and high-quality optical performance. The CAY033 is made from high-quality acrylic material, ensuring durability and reliability in various applications. It operates at a wavelength of 785 nm, making it suitable for a wide range of applications. With an effective focal length of 3.32 mm, it offers versatility in focusing and collimating light in different optical setups.
