Short-Wavelength Near-Infrared Cylindrical Achromatic Lens GL33-025-050-NIRx
Achromatic lenses minimize or eliminate chromatic aberration and also help minimize spherical aberration. They suit applications such as inspection and spectroscopy and form smaller spots than singlets. * For the 25.4mm cemented cylindrical lens, the stated diameter is that of the assembled lens mounting ring. ** If needed, refer to the catalog's OB optical bridge system to select the corresponding mounting ring.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
