Frequently Asked Questions
Optical Lens FAQs
What is an optical lens?
An optical lens is a shaped transparent component that refracts light to focus, collimate, expand or form an image.
How do I choose the right lens material?
Selection depends on wavelength, refractive index, dispersion, thermal environment, laser power, weight, durability and coating requirements.
What coatings are available for lenses?
Options include single-band and broadband AR, laser-line AR, reflective, beamsplitter, filter and protective coatings.
Can you manufacture custom lenses?
Yes. We manufacture custom diameters, radii, thicknesses, edge geometries and coatings from prototype through repeat production.
What tolerances can be achieved?
Tolerances depend on material, aperture, curvature, thickness and inspection requirements. Send your drawing for an engineering review.

Engineering Recommendation
Specify the Lens for the Optical Function — Not the Highest Number
Lens performance depends on the complete optical system. Radius, center thickness, material, surface quality, centration and coating should be balanced around wavelength, aperture and imaging requirements.
Start with Optical Function
Define focal length, working distance, aperture and wavelength before tightening manufacturing tolerances.
Choose Material by Spectrum
Use transmission range, refractive index, thermal behavior and durability to select the substrate.
Control What Affects Imaging
Radius accuracy, centration and transmitted wavefront can matter more than unnecessarily tight cosmetic specifications.
Match Coating to the Source
Specify AR, BBAR or laser-line coatings around the actual operating wavelength and angle of incidence.
Practical specification: tighter tolerances can increase cost quickly. COE can review the drawing and identify where precision adds optical value.

Five Lens Specifications Worth Reviewing Carefully
Radius Tolerance
Specify radius accuracy according to focal and imaging sensitivity.
Center Thickness
Thickness affects geometry, mechanical integration and optical path length.
Centration
Control decenter and wedge where optical-axis alignment is critical.
Surface Quality
Choose cosmetic requirements appropriate to scattering and laser sensitivity.
Coating Band
Define wavelength range and angle of incidence rather than requesting a generic AR coating.
