Precision 2.9mm plastic aspheric lens with 2.9mm BFL, made of PMMA. Supports 450–980nm wavelength range for compact optical systems and laser collimation.
CL1P-D29F29
Description
The CL1P-D29F29 Plastic Aspheric Lens is a compact, high-precision optical lens engineered for collimation and beam shaping in the 450–980nm spectral range. With a 2.9mm outer diameter, 1.55mm height, and a back focal length (BFL) of 2.9mm, it’s well-suited for integration into small and lightweight optical systems.
This lens is made from PMMA (Polymethyl Methacrylate) — commonly known as acrylic — which offers excellent optical clarity, durability, and cost efficiency. Its aspheric surface reduces spherical aberration for improved beam quality and focusing performance, making it ideal for use with laser diodes, photodetectors, and miniaturized optical assemblies.
Key Features:
- Size: 2.9mm diameter × 1.55mm height
- Back focal length (BFL): 2.90mm
- Material: Optical-grade PMMA (acrylic)
- Aspheric surface for reduced aberration
- Wide spectral compatibility: 450–980nm
- Lightweight and affordable design
