Shanghai Optics Collimating Lenses

The collimating lens is typically made up of an aluminum housing with one or more lens elements and is designed to have the required focal length, diameter and mount. The main purpose of a collimating lens is to collect the light from a light source and produce parallel light beam with the required spatial resolution. A collimating lens can be attached directly to the measurement device or testing instrument. Collimating lenses can slide relative to lens fixture for adjusting the focus position. We provide many different types of standard collimating lenses. Our standard collimating lenses including aspheric and achromatic lenses can be used for many different light sources such as highly divergent laser diodes. Our standard collimating lenses can convert divergent laser beams to well-collimated laser beams that enter beam expanders for interferometry, laser material processing and laser scanning applications. For reducing the lead time, you can build your own beam expanders to meet application requirements by selecting different sets of our standard collimating or focusing lenses. Using our standard collimating / focusing lenses, the beam expander can be designed to have magnification up to 10 times for the wavelength of 405nm, 543nm, 633nm, 780nm, 1064nm, 1310nm, 1550nm and 2000nm. We also provide custom collimating lenses for projecting a source at infinity for infinite conjugate testing of optical systems. The collimating lenses can consist of several optical elements. The selection of optical materials and optical configuration depends on the entrance pupil diameter, wavelength, focal length, and field of view of the optical system under test.
