Infrared (IR) Aspheric Lenses
A single-element aspheric lens shape used across infrared imaging and sensing systems.
Share requirements, quantities and a drawing if available. Specifications and supply terms require confirmation.
Overview
An aspheric lens has a surface profile that departs from a simple sphere, which lets a single element correct aberrations that would otherwise need multiple spherical lenses — a real, well-documented reason aspheric lenses are used in compact IR imaging systems (e. g. thermal-camera modules), where reducing element count and weight matters. This hub page links to the material-specific pages: Germanium Aspheric Lenses and Chalcogenide Aspheric Lenses. Procurement review should center on using an aspheric prescription to reduce element count or aberration in an infrared assembly.
Key Selection Points
- Single-element aspheric design can replace multiple spherical elements in a compact IR module
- Available in more than one IR material (germanium, chalcogenide glass) depending on the application
- Used in thermal-imaging and IR sensing systems where size/weight matters

Lens Geometry & Selection Guide
This module explains how lens geometry changes the selection path and the information required from the optical design. For Infrared (IR) Aspheric Lenses, the module focuses on using an aspheric prescription to reduce element count or aberration in an infrared assembly.
- Show surface orientation, optical axis and conjugate or beam condition in the drawing.
- Include focal length, prescription and aberration targets with the enquiry for feasibility review.
- State tolerance and manufacturable-range requirements on the drawing for review.
- Product-specific review: connect infrared band and material with effective focal requirement and document the trade-off against a spherical infrared lens.

Frequently Asked Questions
What is an aspheric lens and why use one for IR imaging?
An aspheric lens has a non-spherical surface profile that can correct optical aberrations with a single element, which is one reason it is used in compact IR imaging modules where reducing the number of elements and overall weight matters.
Which material should I choose — germanium or chalcogenide?
Both are used for IR aspheric lenses; see the Germanium Aspheric Lenses and Chalcogenide Aspheric Lenses pages for material-specific detail, or tell us your wavelength band and application and we will help you choose.
Which specification should be fixed first for Infrared (IR) Aspheric Lenses?
Begin with infrared band and material. It determines how aspheric prescription and orientation and effective focal requirement should be evaluated before the mechanical details are finalized.
When is Infrared (IR) Aspheric Lenses a better fit than a spherical infrared lens?
Choose between them by testing the requirement for using an aspheric prescription to reduce element count or aberration in an infrared assembly. If that requirement is absent, the comparison product may provide a simpler procurement path.
What should an RFQ for Infrared (IR) Aspheric Lenses include?
Provide the optical prescription or sag table rather than only a focal-length request. Also include quantity, drawing revision and the required acceptance evidence. Final availability is confirmed during quotation.
