Lens selection starts from system geometry
Focal length, diameter, working distance, and sensor size usually narrow the lens options before coating is considered.

How to Choose
Select lens type by optical function: plano-convex for focusing/collimation, biconvex for imaging, biconcave for beam expansion, and achromatic lenses when chromatic correction is needed. Confirm focal length, diameter, material, coating, and working distance.

Related Engineering Notes
Coating and wavelength range
Choose coating around the actual operating band. A lens optimized for visible light may not be suitable for NIR or UV work.
Prototype before locking the design
For custom optical systems, validate imaging or collimation performance in the real mechanical layout before scaling production.
FAQ
Which lens type should I choose?
Use the optical function first: focus, collimate, expand, image, or reduce chromatic error. Then choose geometry and focal length.
Are coatings available for lenses?
Yes. Anti-reflection coatings can be specified for visible, NIR, laser, or custom wavelength ranges.
Can lens dimensions be customized?
Yes. Diameter, thickness, material, coating, and focal length options can be discussed for OEM needs.
